Subject: Need testers for FIFO patches

I have a set of patches to the 0.96 and/or 0.96a kernels which add
FIFO special files to the kernel, and 'fix' the existing pipe code to
perform the atomic writes required by POSIX. Additional changes have
been made to allow non-root users to create FIFO special files with the
mknod() call, or the program by the same name.
The modified system seems pretty stable on my machine, and I am now asking
for people willing to try my FIFOs out on their own systems. I would, of
course, prefer people who have some application for FIFOs so I can get some
feedback on the standards adhearance and general usability of my FIFOs.
Once I can find three people who have applications requiring FIFOs who can
get the applications to run w/o significant modifications, I will post
the patches and send Linus a copy for possible inclusion in the next
release.
NOTE: The FIFOs implement, to the best of my knowledge, the POSIX-required
behavior. The brain-dead O_NDELAYisms of SysV are not implemented, so
applications written for SysV which open the FIFOs with O_NDELAY will
probably not work.
The ability to open a FIFO with O_RDWR (to force read() to block when there
is no process writing the FIFO) is supported, so servers/daemons which
use a FIFO as a request queue will work.
My thanks go to Brandon Allbery and Leslie Mikesell for bringing the
atomic write requirement to my attention, and to Bruce Evans for making
the need for O_RDWR support clear to me.
Thanks also go to Jim Burns who has agreed to be my first guinea pig.

^^^^^^
Clarification:
This means the same set of patches works on either (since none of the
relevent files were changed in the transition to 0.96a)

I have solved this problem now, and thought I would post a quick
note for whoever was interested.
The problem was that I had set the environment variable LOGNAME to
my last name (furnish) rather than the name of the account I was
using (user--from the mcc interim distribution). Why did I do this?
Two reasons. First, I am using the RCS port to Linux (thanks to whoever
did it) and also CVS (compiles trivially easy if anyone cares). These
require the environment variable LOGNAME to be set. Secondly, I was
using the user account instead of anything else because the last time
I went and customized my system giving accounts to every member of my
family etc, the disk got totalled a few days later. it was my fault, but
I just never got up enough interest in heavily customizing the system
ever since. So I was using the "user" account, but assigned LOGNAME
to my own last name.
For some strange reason, this caused emacs to report "Error in init file".
This was particularly vexing since I did not _have_ an init file.
In any event, the problem is resolved, and if any one cares to use RCS and
CVS, you should be advised of this silliness.

The zeros are for drive geometry... you don't need them on a hard drive.
Leave them at zero.
Try setting the 12 to a 16. That is they type of FAT the partition has.

fdisk-0.92 (I believe included with the MCC-interim release) supports
extended partitions. I have 6 partitions on my 200MB disk:
10 MB DOS, 10MB swap, 20MB root, and 3 user partitions
(because of the 64MB partition limit). It works great.

to which I answered yes, and when i did an ls, the file was gone!!
This didn't happen under .95, .95a, .12, .95c++, but it is happening

Frequently Asked Questions About X386 (with answers)
----------------------------------------------------
1. What is X386?
X386 is the port of the X11 server to System V/386 that was
done by Thomas Roell ([email protected]).
It supports a wide variety of VGA boards.
There are 2 major versions: X386 1.1 is based on X11R4,
X386 1.2 is included in MIT's X11R5 distribution (ie. you
don't need to patch it into the MIT source anymore).
2a. Where can I get X386 1.2 (X11R5)?
The X386 1.2 sources are available at any site that distributes
the X11R5 source (too numerous to list here, but includes
export.lcs.mit.edu)
The version 1.2 binaries are available at:
ftp.physics.su.oz.au in Esix_4/x11r5/Binaries
nic.funet.fi in pub/unix/386ix/svr4/x11r5
ftp.win.tue.nl in pub/X11R5-esix
2b. Where can I get X386 1.1 (X11R4)?
X386 1.1 is available both as a binary release or as source
patches (apply patches to MIT's X11R4 source tree).
The fonts are available separately, since they are common
for all operating systems.
The official ftp site is flop.informatik.tu-muenchen.de
(131.159.8.35), /pub/i386/X11R4
808424 bytes X386.1.1b.tar.Z source patches
3566993 bytes X386core.SVR4.tar.Z binaries for SVR4
7348521 bytes X11R4core.tar.Z 1.1a binaries
395521 bytes X386.1.1b.isc.Z 1.1b server binary
3307520 bytes X11R4fonts.tar fonts
It is also available on the following machines:
- piggy.ucsb.edu (128.111.72.50), /pub/X386.
808424 bytes X386.1.1b.tar.Z source patches
3566993 bytes X386core.SVR4.tar.Z binaries for SVR4
3307520 bytes X11R4fonts.tar fonts
Please use after 6pm Pacific, as these are large files.
- ftp.win.tue.nl:/pub/X11R4_386
- NSTAR Public Access Unix 219-289-0287
{[email protected], ..!uunet!news.rn.com!larry}
3. What operating systems does it run under?
X386 will run on following Unix operating systems:
- Dell SVR4
- Interactive 386/ix, 2.0.2 or later
- ESIX
- SCO Unix (release 3.2v2.0)
- AT&T SVR4 and SVR3.2
- Microport SVR4
- MST SVR4
4. What VGA boards are supported?
ET3000 (for ex. GENOA 5300/5400)
ET4000 (Tricom, STB PWR Graph, Sigma Legend, etc.)
GVGA (Genoa 6400)
PVGA1A (Paradise VGA Professional)
WD90C00 (Paradise VGA 1024)
5. Why won't my xterm run properly?
If your kernel is not built with the consem module, you should define
CONSEM=no in you enviornment. Otherwise xterm won't run.
csh users should use 'setenv CONSEM no'
6. I can't compile X programs. Am I missing a library?
you must include the BSD (Sockets) API by including -linet in your link
list. Also, for anything that uses the /dev/ptmx 'clone' devices,
use -lpt.
SCO Unix uses -lsocket for the socket library.
In summary, add '-linet -lpt'
after the -lX11. (It won't work if it is not AFTER the -lX11)
Or use instead -linet '/usr/lib/X11/X386/etc/inetemul.o' which
includes some dummy functions, which always will return an error,
but are *very* good for linking.
7. Everything works fine if I use xinit, but I can't use xdm.
It gives me an error that it can't open the mouse.
Why would the server work fine under xinit, but not xdm?
How do I fix it? (I am using the Xque* drivers under SVR4)
This is caused by a bug with the Xque drivers in SVR4.
Dell's SVR4 has fixed this problem (which exists only
with X386 1.1, not X386 1.2).
[email protected] (David E Wexelblat) is using the following
xdm (X11R4pl18) patch successfully:

sigsetmask (0);
+ #endif
#endif
#ifdef SIGCHLD
(void) signal (SIGCHLD, SIG_DFL);
8. How do I find out what clock frequencies are on my VGA board?
X386 1.1 includes a DOS program, /usr/lib/X11/X386/etc/clock.exe, that
you can run (under DOS of course!). It will report all the clock
frequencies that it can find. You can then use this information
when setting up your Xconfig file.
X386 1.2 will automatically find this information when it boots.
David E Wexelblat ([email protected]) maintains a database of known
clock settings for VGA cards and monitor settings. This database is
available from him (for the latest copy), and is kept on
export.lcs.mit.edu in ~/contrib/X386.modeDB.Z, which is updated
occasionally. Obtain a copy of this database. It just might have the
settings you need. If you create new settings, please send them to
David for inclusion in the database.
8a. OK. I have my VGA clocks, and my monitor specifications. How do I
generate mode lines for Xconfig?
First check out the mode database described for question 8. It has lots
of monitor timings contributed by X386 users. It also has the VESA
standard definitions. If the database does not have definitions for
your monitor, try the VESA timings.
If neither of these options work, the CONFIG file with the X386 contains
a tutorial on how to come up with these timings. It may be helpful to
start with setting that almost work, and use this description to get
them right. When you do, send the information to David Wexelblat for
inclusion in the database.
9. How do I switch session under SCO? The normal sequence does not work.
Try ALT-CTL-F{n}
10. I can't get my bus mouse to work!
I had a lot of trouble too! So far, the only way I could get a
bus mouse to work (on SVR4) was to use the Xque drivers and set
up my /usr/lib/mousetab for a bus mouse 'vt00 bmse'.
(This involved re-installing the mouse driver for bus mouse)
People running ISC have reported that using an Xconfig of
'Busmouse "/dev/logi"' works too.
11. Any tips on compiling X11R5?
1. You will need lots of disk space (around 150Meg for the MIT core).
2. If using the standard C compiler, make sure that you don't have
/usr/ucb before /bin in your path.
3. Follow the advice of Steve Hite ([email protected]):
"DON'T use the C shell on Esix 4.0.3a. The X library is HUGE and
csh complains about too long of an argument list. The Korn shell
will work just dandy."
4. Look at mit/server/ddx/x386/README and follow any instructions
for your particular platform.
5. Change the line in server/Imakefile that reads:
SYSLIBS = -lm /usr/ucblib/libucb.a
to read:
SYSLIBS = -lm -lc /usr/ucblib/libucb.a
This ensures that the directory reading routines from libc.a are
used intead of the ones in libucb.a (BSD version of readdir).
You might want to extract ndbm.o, bcopy.o and bcmp.o from
libucb.a (ar x) into a private library instead (or use GNUdbm).
6. There is an unofficial bug fix for the polygon drawing routine,
it is available for ftp from:
ftp.win.tue.nl:/pub/X11R5/fixes/unofficial-X386fix
ftp.physics.su.oz.au:/Esix_4/x11r5/Unofficial_x386_fill_patch.Z
7. You may want to disable building the PEX stuff, since it
runs miserably slow on most machines.

No, this is an exception to the normal rules of permissions. Actually,
I guess it IS a normal rule, but it's not part of the basic one, 'if you
don't own it, you can't have it.'
If there is a file in a directory owned by you, you have rights to it, no
matter who owns it. I forget just to what extent the permissions are, but
you have at least the right to delete it.
Notice that you couldn't delete something in the /bin directory, for example.

I have a couple of questions for the Legal-aware out there.
I am going away from my internet access for the summer (sniff). I am taking
about 40Mb of various sources and info, however, and I will be taking a
CD-ROM of X11R5 and all the GNU sources with me, so don't anyone worry
about my boredom, I've got about 650Mb of stuff to keep me busy.
However, one of the things I'd like to do is play with merging some of the
BSD and Linux sources. Not really merging per se... I want to take some of
the working pieces of BSD and graft them into Linux.
What I'm wondering is, what are the legal ramifications if I want to give
out what I've accomplished? For example, I want to port the CD-ROM
driver to Linux. It is under the BSD Lisence.
Can I give out copies of the finished project? If it were good enough,
could Linus include it in, say, an MCC release of Linux? Would Linux
have to start displaying Regents-Of-UC-Berkeley copyright notices?
I'd like to add to Linux, but I don't want to cause the Linux lisence
to change in the process. And I don't have the knowledge to write a CD-ROM
driver myself (though a GREAT deal of it will be pretty close!)
Another idea I'd like to play with (god forbid) is installable device drivers.
I know, I know, it's almost like a DOSism compared to the UNIX way of doing
things. BUT, it's a convenient DOSism, and it could really help make
Linux configuration easier.

I've been playing around with Linux, and am about to take a dive into the
kernel in a big way. So I;ve got a few questions about where Linux is
headed, so I don't step on anyone's toes in the process (or waste my time).
Right now, Minix is _the_ filesystem for Linux. However, with VFS on the
horizon, it seems we will be able to hook in any filesystem we want.
There's full source for UFS available with 386BSD (see my other post)
and others have been working on a 'bigfs' to alleviate the minix filesystem's
most grievious problems.
However, is there any consideration being given to planning a move to a
different 'standard' filesystem for Linux? Minix is just inadequate for
many (most?) needs. For example, I'm working on a connectionist network
simulator, and it NEEDS long filenames (well, it's damn inconvenient without
them). Now, I'm trying to edit the sources, but we're talking about 7-8Mb
of code here. It's much easier to just rewrite the filesystem! Patching
the Minix fs for longer names is possible, but that's a kludge.
I digress. Well, are there any discussions? Pardon me for not searching
on my own, but I've got to leave in a week and a half, and I'm in finals
right now.

I was just logged in as a regular user, and there was a file in my home
directory that belongs to root, and I did an rm to it
rm -f test.c
and this is what I saw:
rm: remove 'test.c', overriding mode 0644?
to which I answered yes, and when i did an ls, the file was gone!!
Standard Unix semantics: If you have write access to the containing
directory, you can delete any file in the directory. BSD systems have
an enhancement where if the sticky bit is set on a directory, only the
owner of the file can delete it. This is why BSD-derived systems have
/tmp set to mode 1777.
Adding this functionality to Linux would not be difficult. A few lines
of code to fs/namei.c.
I think this is a security risk, but I am not an expert. 😉
Nope, no security risk; at least not from this behavior.

Distribution: comp.os.linux
Organization: Long polymers in double-helix formation

Lines: 51
For those of you that missed or skipped it, I found a circuit for a stereo
sound player that works off of the parallel port enclosed with an Amiga .MOD
file player for DOS. I thought that it'd be good for Linux because:
A: It's really cheap to build
B: It works on the parallel port, so we don't need to write a new kernel
driver for it.
C: It's a nifty hardware hack, to go with all of the software hacks already
in Linux.
Well, since so many people have mailed me asking for more information,
I thought I'd post the sources for the DAC chips needed for the circuit.
To get the circuit itself, you can get the file MP219B.ZIP from Simtel or
any of its mirrors in the directory msdos/sound. This is an archive
containing Modplay 2.19b, a great .MOD file player for DOS. The circuit
(actually, several circuits) are included in HARDWARE.DOC(I didn't post
this because I wasn't sure I could distribute it apart from the rest of the
archive). The one you want is the Stereo-on-1 board. As one person wrote
me, real-time applications may not run well in a multitasking environment,
but I think it'll work well for at least FM sound synthesis and single
channel samples,if not for full 4-channel stereo sound.
The chips listed for the circuit are 2 Plessey ZN428 8-bit DACs. The docs
say any D/A with input latches should work, as long as it latches the data
bus when pin 4 is low. If you want an exact match, you can order from:
JDR Microdevices
2233 Samaritan Drive
San Jose, CA, USA, 95124
(800)-538-5000 (Orders)
(800)-538-5002 (Tech support)
Theirs is a good catalog for _anyone_ to have, IMHO.
Part numbers DAC-0800($1.99 US) or DAC-0808($2.49 US) should work, with
the DAC-0808 being recommended as the closer match. You can also order
the other small components and the cables you need from them. You may
need to get some things elsewhere. If you hate soldering, you can
assemble the circuit on a solderless breadboard, price about $2 to $6
US. If it works well for me I may etch a board for it.

Unfortunately, to use it, you have to add a supplied routine to your lib
(libc, I think), and it will only work for anything compiled w/the new
routine, which lets out all the mcc-interim stuff.

In case somebody doesn't know. The official gcc ftp site for Linux is
banjo.concert.net under /pub/Linux/GCC. For now, gcc 2.11c is
officially released. There are also a few testing releases. To use the
the testing gcc, you MUST join the GCC channel.
Before you install the gcc, please read all the release notes up to
the version you are installing.

Why this system?
I noticed people were asking questions like "who was porting
SCSI driver to Linux?" or "what is going on with X?". This
system tries to make contacts easier and possibly we avoid
duplicate work.
It saves time to admin mailing lists.
Mail-Net gives for the user possibility to create his own
mailing lists (here called channels).
Linux-Activists mailing list:
The former mailing list is just one channel on the system.
The default channel is called "normal".
Send your linux-activists mail to:
[email protected]
and remember to have at your mail header or
the first line of your mail body
Mn-Key: normal
How to use mail-net software:
You send mail to the server defining what you want. Now
I do have only commands sent within mail header lines or
the first line of your mail body.
The header lines are those lines which contain fields
like "To:" or "From:".
I hope, that the admin and mail goes to the same address,
if it won't work - I have to make other e-mail address
for requests.
Commands:
MN-Admin: create channel_name
The system creates a channel for your discussion
interests, like
MN-Admin: create SCSI
would create channel SCSI (where you could speak
about SCSI w/o taking "looser mail"/"line noise").
Join is automatically done for the channel creator.
MN-Admin: delete channel_name
😉 Channel deleting is not needed now ...
MN-Admin: join channel_name
Join to some discussion channel. The channel must
exist prior joining ...
MN-Admin: leave channel_name
You leave the channel.
Like leaving the main channel i.e. Linux-Activists list
MN-Admin: leave normal
you can still use other channels ... naturally.
Admin commands can be sent to the mailing list
([email protected]) or to the
request address ([email protected]).
Mailing to the Linux Activists list
The e-mail address still is:
[email protected]
You need to have definer MN-Key: channel_name if you would
like you mail to go to some channel [, else it will go to the
default "normal" channel.] You need to have key for the
default channel too, that is:
MN-Key: normal
This filters out the multiple error messages I managed to make
having sender as the whole list (and all the mailers sent
and are sending error messages to the whole list).
Need to send mail to the SCSI channel:
MN-Key: SCSI
Notice
"X-MN-Key:" etc definers are supported, Mn-Key, and Mn-key
are valid definers.

I got the binaries for X off of banjo and installed them as per the

I'm trying to see if I can get X to work within just three megabytes

bit I'm getting more memory soon...). Six megabytes of swap space.
With the 'bootimage' boot disk provided with the X stuff, I try
startx and the server dies with "No screens found."
With the 0.96a boot disk, the server just dies and says "giving up."
If I comment out the part about the mouse in Xconfig, I can get the

For those who have no idea what this is doing in comp.os.linux, this is
one of three fidonet 'backbone' operators. The newsgroup of comp.os.linux
is being gated to the fidonet world. Something that I have been doing
for the last month and the 'backbone' is the Fidonet way of passing
newsgroups (echo's).
Fidonet is a conglomeration of over 16,000 systems world wide, it is a
store and forward type network, using ma bell as the medium for sending data.
One of the 'rules' for Fidonet to get an echo on the backbone, is that it
must have a moderator. I have assigned this position to myself;-) So if there
are any complaints from the newsgroup side, please address them to:
[email protected]
(not sure if my return address above will get to me, as
that address is for gating and testing purposes)
For those on the fidonet side, I have set-up here as a 'clone' of
tsx-11.mit.edu and banjo.concert.net. The files you see metioned will be
available here via f'req or 9600+ user D/L. 1-206-235-0189, As soon as I can

I presume you have made /dev/tty0. If you have then, your video card is
very likely not supported. I THINK the message 'No screens found' is
printed by X if it doesn't recognize your chipset.. At least this is the
message it gives when I tried it by accident on a Trident card.

I've heard that there are PC controllers that appear to dos as

will Linux treat this controller the same way. I would appreciate
recomondations if available. I've been offered the use of a Maxtor

This is the behavior that Linux follows. However, jgifford's

Q : What SCSI hosts are supported?
A : The Adaptec 1542 (The EISA bus master 17xx may work with
minor changes), Seagate ST01/ST02, (These are
repackaged Future Domain 88x series boards.
If you have an 8 bit future domain controller,
you may be able to modify the seagate driver
to detect your card to. If any one does this,
please send diffs.), and Ultrastor 14F are supported in the
stock distribution.
Also, patches are available for the WD7000 FAAST, and Future Domain
16 bit controllers.
At this point, the Adaptec 152x series, and 17xx series
DO NOT WORK.
Q : Which disks ?
A : Anything that works with your host adapter electronically, and
is new enough to support a December 1985 draft of SCSI-I.
Sysquest removable drives are known to work. However, DO NOT
remove a mounted cartridge. This will trash your filesystem.
CDROM should also work, but we don't support the High Sierra
filesystem.
Q : What about SCSI tapes ?
A : The stubs are sort of there. The detection stubs are there,
there is a raw SCSI ioctl which forms the basis for much of the
tape driver (it goes between user / kernel space, where as
the block driver code operates entirely in kernel space),
all that remains is completion of enough ioctls
to support an mt command. It's 1-2 days of coding
and debugging once someone gets around to it.
Q : How do I get SCSI information?
A : Subscribe to the SCSI channel of the linux-activists mailing list.
mail [email protected]
And put
X-MN-Admin: join SCSI
in the header.
Mailing [email protected]
will get you a list of commands.
Q : How do I partition the disk?
A : The linux partitioning programs don't work, as you might have noticed.
Partition the disk under DOS (pfdisk compiled for DOS will work),
or if you are a masochistic hacker type and familiar with your SCSI
BIOS's remapping scheme, use dd and a binary capable editor =8^)
The problem with partitioning SCSI disks and Linux is that Linux
talks directly to the SCSI interface. Each disk is viewed
as the SCSI host sees it : N blocks, numbered from 0 to N-1,
all error free. There is no portable way to get disk
geometry.
However, DOS doesn't like things like this, it demmands that
BIOS present it with a normal Cylinder / Head / Sector
coordinates. So, BIOS does, and it comes up with some fabrication
that fits what DOS wants to see. You don't want to disagree with
what BIOS thinks when you write the partition table.
Q : Where is the latest version maintained?
A : headrest.woz.colorado.edu:/pub/linux
Since SCSI made it into .96, this is mostly alpha/beta
test for new things. Right now,
an interrupt driven Seagate driver is what's there.
It works for me, but your mileage may vary.
Join the list before you grab anything.
Q : what about extended partitions?
A : not yet. Let's just say that I almost have a very
large drive up on a SCSI->SMD bridge, and
that it's a priority.
Q : I get a message saying READ CAPACITY FAILED.
What does this mean?
A : One of two things. First thing is that there is a bug in
the midlevel error handling code. When an error
condition is returned, things aren't retried. Some
SCSI disks get unhappy at the sight of the
initialization routines, and will return an
error condition for the first "real"
command that they run. INQUIRE doesn't count,
since that will allways return successfully,
irregardless of pending error conditions,
unless your drive is Kaput.
You could also have a flakey disk, but this is
unlikely.
Q : What are the major / minor numbers for SCSI drives?
A : Right now, it is theoretically possible to have
21 SCSI devices in the system. With SCSI-
MFM / ESDI / SMD bridges this can be even
more drives, as each id may have several drives on it
each set up as a LUN of that id. Needless to say,
if we have allowed for 16 partitions per SCSI drive,
we're pushing the limits on minor numbers. Therefore,
a yucky dynamic numbering scheme is used.
Block device major 8 is used for SCSI drives. I
personally like /dev/sd[n][p], where n is the drive
number, and p partition letter - but this is
entirely personal preference.
Minors are assigned in increments of 16 to SCSI disks
as they are found, scaning from host 0, ID 0 to host
n, ID 7, excluding the host ID. Most hosts
use ID 7 for themselves.
A minor where minor mod 16 = 0 is the whole drive,
where minor mod 16 is between 1 and 4, that partition,
and extended partitions are not yet implemented.
Example : I have four SCSI disks, set up as follows
Seagate ST02, ID=0
Seagate ST02, ID = 5
Ultrastor 14, ID = 0
Adaptec 1542, ID = 0
The first disk on the seagate at ID 0 will become
minors 0-15 inclusive, the second at ID5 16-31
inclusive, the disk on the Ultrastor 32-47, on the
Adaptec 48-63.
Q : I can't use more than 2 SCSI disks.
A: Change MAX_SD in sd.h, MAX_SCSI_DEVICE in scsi.h, and recompile the kernel.
Q : How do I reduce kernel bloat and eliminate the drivers I
don't want?
A : Simply #undef CONFIG_DISTRIBUTION in
include/linux/config.h, and define the
macros for the SCSI hosts you want
enabled.
Q : What about bugs?
A : It works on MY hardware. It works on Tommy Thorn's
Adaptec system, Dave Gentzel's Ultrastor, Thomas
Wuensche's WD7000, Rick Faith's Future Domain,
and quite a few other systems.
Bugs that are there will mostly be very hardware
specific, and nasty to track down. SCSI should
be basically error free - consequently, the
error code has not been heavily tested, and
there are known bugs in it.
If you have found a bug, please mail it
to the mailing list with specifics of
your hardware. Other people may have
the same problem, a solution, etc.
Chances are I will provide you with a debugging
version of the kernel, which will dump out important
SCSI information and let me see what exactly is
going on.
Q : What are the known bugs?
A : The seagate driver should fail on i486, and i486sx machines. This is because
the seagate uses memory mapped I/O, and if it gets the chance, the
i486 will go for the internal cache, bypassing the memory mapped
registers of the Seagate SCSI host.
386 cache machines will not have problems IF the Seagate's address
space (typically C8000 - CAFFFF) is marked "non cacheable."
This can be set in the XCMOS of most machines.
The error routines are imperfect, and this causes READ CAPACITY
to fail in sd_init.
Many of the drivers cannot abort a command that is in progress - if some
thing
goes haywire, all drives off that controller will hang.
Q : Why can't I swap to a SCSI disk?
Q : Why can't I mount a SCSI disk as root?
A : This was due do a race condition that has since been fixed (I think).
It only manifested itself in drivers using the command()
interface (see bellow), but this interface isn't used very much
as it was there mostly for develeopment.
Q : Why does Linux "hang" when the disk is accessed?
A : There are two possible interfaces between mid and lowlevel SCSI routines.
These are the queue_command() and command() interfaces.
The difference between the two is that queue_command()
provides a way to do generic, interrupt driven SCSI,
whereas command() is not interrupt driven.
The latest Seagate driver (in testing), WD7000 and Future Domain 16 bit
use the queue_command() interface, Adaptec has it disabled, someone shou
ld
recompile it with it enabled, and I don't know about Dave's latest Ultra
store
driver.
Q : I get SCSI timeouts.
A : If you are using the latest interrupt driven seagate driver,
you will have to jumper the card for IRQ5. The factory settings are
for MSLOSS, and have interrupts disabled. Interrupts are controlled
by the W3 (ST01) or JP3 (ST02) jumper, which should have pins FG
shorted. See your manual.
Q : What future developments are planned?
A : The following changes will occur (listed from highest to lowest priority) :
- Support for extended partitions will be added
- Support for LUN != 0 will be added
- Support for tapes will be added
And, best of all there will be a new interface to the SCSI routines that
will facilitate
scatter/gather, allow multiple outstanding commands (1 per LUN), and all
sorts of
other goodies.

I know that there are versions of fdisk that support extended partitions,
but I never saw an announcement that the kernel itself was reliable on
them. Also, the latest thing I saw from Drew was that they were not
supported for scsi. Has anything changed? What device minors do you use?
Thanx.

I just finally got around to upgrading my system.
From 0.95a to 0.96a, and GCC 1.40 (0.95a) to GCC 2.11c (0.96a).
I'm having some strange problems...
1) When first install, it would not run at all.
I tried the simple old hello.c and ld complainted about
something not being there. I check everything I could think it
might be looking for. Nothing "wrong".
Well, after a while I stumbled across the 0.96ainc.tar.Z.
I install it over the includes in /usr/include. (More history for
step 1. I had gotten 0.96inc.tar.Z and did what release 2.11a said.
I felt that the headers in 0.96a really should be in there, not 0.96.
So, I copied the headers on top of the 0.96. But that didn't fix anything)
Back to reality....
This fixed many things. One is that hello.c would compile. 🙂
But other things would not. Common errors are:
No such file or directory (coming from ld.. Like before)
Parse error in stdio.h (I was compiling reboot.c I got from here)
I looked at stdio.h and I can't see anything wrong..?? What is going on?
Enough moaning.. 🙂

Got a weird one for ya.
You start something and do a contol-c to stop it. What happens?
Sometimes nothing and all is right in the universe. Or...
I guess the moon is where it shouldn't be, but sometimes when I
start typing it won't show up on the screen til I hit return.
Why?
To fix this is usually logout and login again.. If
really tough, try to kill the base shell from another console.
(I don't have a working ps yet.. I need the system file and I
don't dare compile the kernal until I get the bugs out...)
I have not applied the patches level 1 I find after the fact..
Ideas? Linus?

This is standard unix behaviour, so long as you have write perms on the
directory itself. I would be surprised that 0.95c+ didn't do it also.
What IS a security problem is you can chown a file w/o clearing the suid
bit. Fortunately, at least, chown doesn't let an ordinary user change
ownership to root!

Indeed. Here is a snippet of code that should enable/disable ctrl-alt-del:
----------
#define __LIBRARY__
#include
#include
static _syscall3(int,reboot,int,magic,int,magigtoo,int,flag)
int main(int argc,char ** argv)
{
if (argc == 2)
if (!strcmp("on",argv[1])) {
reboot(0xfee1dead,672274793,1);
return 0;
} else if (!strcmp("off",argv[1])) {
reboot(0xfee1dead,672274793,0);
return 0;
} else if (!strcmp("now",argv[1])) {
for (argc=0 ; argc < 5 ; argc++) {
sync();
sleep(5);
}
reboot(0xfee1dead,672274793,0x01234567);
return 0;
}
fprintf(stderr,"usage: reboot [on|off|now]\n");
return 1;
}
----------
The program can only be run as root, or nothing will happen. Usage is:
reboot on - accept ctrl-alt-del (default)
reboot off - ctrl-alt-del is ignored
reboot now - reboot after syncing and waiting 25 seconds (so that you can ^C it)
And as with most code I write, none of the above has ever been tested: I
only guarantee that this is how I intended the reboot system call to
work.

It's already in there: I think 0.96 and earlier didn't handle the
rename() system call correctly (ie you could move a file even if it
wasn't yours), but 0.96a should have that fixed too. Other than that,
sticky directories have worked since 0.12, I believe.

My chipset is WD90C00 which is in the x386 FAQ.
From x386 FAQ.
4. What VGA boards are supported?
ET3000 (for ex. GENOA 5300/5400)
ET4000 (Tricom, STB PWR Graph, Sigma Legend, etc.)
GVGA (Genoa 6400)
PVGA1A (Paradise VGA Professional)
WD90C00 (Paradise VGA 1024)
Does x386 under linux supoort WD90C00 ?

Here is an emacs-lisp file that defines some of the keys on the
keyboard to do reasonable things. I got the first part of this file
from the FAQ, and added some of my own definitions, too.
If you put this in /usr/local/emacs/lisp/term as $TERM.el, where $TERM
is your console type (mine is con80x50.el), it will be automatically
loaded whenever emacs is started.
Here are the definitions:
cursor keys = standard, insert = toggle overwrite mode, delete = ^D,
home/end = standard, num_5 on keypad when not in numlock =
set-mark-command, F1 = help, F2/3/4 = cut/copy/paste, F5 =
auto-fill-mode, F6 = toggle-read-only, F7 = not-modified, F8 =
kill-buffer, F9 = switch-to-buffer, F10 = find-file, F11 =
save-buffer, F12 = save-buffers-kill-emacs
I hope you like these. There is nothing magical about my function key
bindings (though F1-4 are pretty standard); feel free to change them.

While trying to get Linux to run X I connected my old computer as a terminal
to my Linux box. However the sessions that run on this terminal have some
very weird buffering going on: I only get to execute commands when I press
return twice. Also bash doesn't get hold of the characters that I type

Anybody know if this is a bug or did I forget to do a relevant stty command?

As far as I know, when it comes to directories, the permissions are as
follows:
r - you may `read' the directory, meaning, you can do an `ls' on it and see
the files in it.
w - you can write to the directory, meaning you can create or delete files
in it. (which is what happened in this case)
x - you can `pass thru' the directory, meaning you can `cd' to it or anything
below it (providing the permissions on the object that follow allow to be
`cd'ed to.
So, in this case, though you don't own the file you own the directory where it
exists. Hence, you may decide whether the file may exist in the directory or
not. Notice, btw, that `x' is the most important bit of the three as you must
atleast have it turned on for you to BE in the directory -- after you are there
you can read (ls) or write (create/delete).
>Notice that you couldn't delete something in the /bin directory, for example.
Write, you don't own it and the write permissions for you is turned off so
you can't delete it.

Message-ID:
Date: 2 Jun 92 09:09:31 GMT
Organization: Rutgers Univ., New Brunswick, N.J.
Lines: 42
I have a 386sx with an EGA screen and no (usable) mouse. I thought
I'd see if could get MGR to work. Turns out it works fine on an EGA.
However you have to specify 640x350. I.e. run it as
mgr -S 640x350
It won't restore the registers when it exists, so you might as well
reboot when you're done. (Apparently it reads the registered at
startup and puts back the old values on exit. This works fine for a
VGA, but most of the EGA registers aren't readable.)
I had been getting really odd behavior with the pty's. I found out
why. Somehow I had gotten the definitions of the pty's and ttyp's
reversed. This caused most of the trouble. However I do still have
the problem of needing to do something odd to get bash to run in the
window. I followed somebody's suggestion and run getty on pty0 and
pty1. I still have to fix up a few things, e.g.
stty onlcr
to get output to start at the beginning of a line. But basically it
works fine. progman.mgr has an example termcap entry, which you'll
want to add to /etc/termcap, in order to allow your editors, etc., to
run.
Unfortunately I'm afraid I have to say that at the moment I prefer
using the terminal emulator built into the kernel. It's a lot faster,
and I can use color. With an EGA, really there aren't enough bits to
want more than one window on the screen. It would be sort of nice to
have a clock and a few other things, but not nice enough to give up
having a color mode line in emacs, color in my prompts, etc. Also, I
like black letters on white. While MGR has the ability to do inverse
video, it's nearly unreadable. I think it's using intense white,
whereas what you really want is normal intensity. (Unfortunately, it
may turn out that color is too slow to be useful on a 386sx.
Scrolling is already too slow even with monochrome.)
I'll be interested to follow future developments with MGR. Once
colors are working and some more of the tools are working, I'll give
it another try. It does look like it might be more appropriate than X
for small systems. In fact I've even wondered if it might make sense
to try and put it in the kernel as the normal terminal emulator.

So X is out. Vgalib gives us poor people (or students) a

double scalar;

scalar = 480 / 640;
You would expect a value between 0 and 1. You
print it.. What do I get? 0.00000

so I rebooted with the new disk, and watched as the system echo'd
"Loading........................................................"
The system then did a CR/LF and stopped. Period. KB buffer then
fills with keystrokes and beeps to get me to stop trying. Some
thoughts are that maybe bootimag.zip isn't what I need, or maybe
rawrite doesn't like creating a 360k boot disk on a 1.2 mb drive,
or maybe my system just doesn't like Linux (4mb RAM from Gateway),
or maybe I just screwed something up. ALSO, when I pkunzipped the
two files on the Epson XT I use to download stuff, all was well,
but when I pkunzipped these on the 386sx, bootimag unzipped fine
but rootimage "failed the CRC check" so I redid everything with
the same result. I use DOS 5.0 backup/restore to move files that
won't fit the Epson's 360k disks. That's likely not the problem.
NEXT, I'd like to program in a rather stripped-down Linux but am
concerned that maybe the file system, plus basic necessities, gcc
and some kind of debugger, and either vi or an anemic emacs, may
not fit my ten meg available drive partition. My fiancee and I
must use the other 30 megs of this disk for DOS stuff. IFF I do
fall in love with Linux there's a chance I'll eventually spring
for a larger drive dedicated to *x?x, but that's a long way off.
Any suggestions on how I might make best use of 10 mb and where
I might find the best compact software? I assume it's at tsx-11.

Thanks for this info. Since I hadn't gotten very far this weekend,
I just started by installing the 0.95c+ MCC-Interim stuff, and then
0.96a. Works like a charm.
For those who missed my original article, I had booted 0.96a and was
trying to run stuff from the MCC-Interim disks and getting "Memory
Fault" messages. I hadn't installed the MCC Boot disk so I didn't
have the lib92.04.06 library.
Another thing - when I load Kermit5A, and type in command, say,
"set baud 2400", only the first s shows up until I hit return. Has
anyone else seen this?
Thanks,
Brendan

480 / 640 is an integer expression since both of its operands are integers.
It yields the result 0, which is then cast to double before assignment to
`scalar'. You should have written
scalar = 480.0 / 640.0

As usual, I open my mouth before thinking. 😉
Actually, I sent the message to the wrong alias, I meant it to go to about 5
or 6 people, before sending it to the digest and making a fool out of myself.
😉
I have received many corrections both by digest and e-mail, and I must say
thanks everyone for your patience(I didn't get ONE flame out of anyone) 🙂
I had temporarily forgotten the ONE thing I learned in my UNIX class in
college before they tought me the rn command and I found that rrn worked
instead. After that, my studies were never the same. 🙁
Alright, now for the lesson I learned tonight:
LOGIN AS A GENERAL USER for day-to-day work, root can rm ANYTHING 🙁
(including /bin and /usr/bin)
Thanks {insert favorite diety here} daily for that backup diskette you haven't
gotten around to re-formatting yet.
ALWAYS keep an up-to-date backup of important stuff(I have a 20 meg partition
with .tar.Z files I am saving, haven't put on floppy yet)
If you have a buggy program(like tar and compress)and replace them with good
ones, BACK THEM UP!!
I have wiped my tar, compress, and bash(using ash, yech)(I restored everything
else)
What happened was this:
I was compiling elm, when it barfed and said :/bin/chmod no such file,
So I got the BRILLIANT(??) idea to put EVERYTHING in /bin, and make a symbolic
link to /usr/bin(I already had a few links from bin to usr/bin)
I did a mv * /bin, and poof, things are a little dead.
I managed to mount a floppy and cp it's /bin to /bin and then ln -s * /usr/bin
This weekend, I am going to back everything up to another machine's harddrive,
and re-partition and install everything.
My partitioning scheme gives win3.1 a fit.
Oh, well....

Hi there,
I saw an interesting offer for an EISA system which includes a 330 MB SCSI disk
and the Bustek EISA-SCSI controller (742). Now, that there is a Adaptec-1742
I would really like to get this one. However, this would add to the cost
of the system. Now, my question is whether these controllers are compatible.
I know that the Bustek and the Adaptec-1740 will work with OS/2 2.0. What I
don't know is will these work with Dell or Interactive UNIX and 386BSD-UNIX
and especially the Adaptec-1742 with OS/2 2.0. In other words, is it worth
the trouble and cost of changing the Bustek-742 to an Adaptec-1742 ?
Please, post or e-mail your experience. Because others may be interested in
this, perhaps posting is not a bad idea. But, if this question was asked
several times in the last weeks (which is entirely possible), just mail me
the last summary, etc.
Thanks,
Norbert.

The floppy contains a tar image, not a filesystem image. Use
tar tvf /dev/at0 to read the archive and
tar xvf /dev/at0 to expand it onto you disk.

The last time I got an address mark not found error, it was because the
image was too big to fit on the disk (because I had forgotten to
download the file in binary form so it expanded). I doubt if you could
boot off of such an image so it is probably because you are writing a
hopefully good image to too small of a disk. Are you sure you
formatted this disk as either a 1.2MB 5.25" or a 1.4MB 3.5"?

Hi,
I would like to apologize to all those MGR users that were
bothered by the MGR bug that would make the windows act erratically
and wouldn't even let BASH work. Here is a patch to fix that bug.
(It will also enable job control and command line editing on TCSH)
I will be uploading a new version of MGR to banjo this weekend.
This will include a fix for the startrek effect. (THanks
[email protected]) A fix for bash bug. And a utility to turn on
128K mode on TVGA cards. Hopefully color and better mouse support
will come in the future. If you have any patches that you would like
me to include in the next release of MGR please do so as soon as
possible.
(It is embarrasing how simple was the fix for the bash problem)

I suspected this too, so I just looked on the chip on my VGA card.
It says:
PARADISE'88
PVGA1A-JK
00-02 8905
The man page on X386 seems to imply that this card is supported.
By the way, does anyone know where you can get clock.exe without

I was doing some work trying to see if I could get Zsh 2.20 up and running
under Linux.
A few anomolies:
Why does
getpgid(void);
setpgid(void);
Zsh wants to supply one arg to getpgid, and two to setpgid.
sigblock and sigpause are not found. From the looks at signals.h, they
are not currently implemented. I would assume this means zsh is a no go?
EWOULDBLOCK is not defined in errno.h. I'm assuming this is due to the
sigblock functions.

It's frustrating. 🙁
While everything else I compile works fine, Elm refuses to function properly
for me.
It will read mail and do all the neat things it's supposed to do, but is NOT
sending mail.
I've compiled smail2.5, and if I use it locally feeding it a message on stdin,
it generates mail, and elm can read this. However, when I hit the S)end key
in Elm, I get segmentation errors.
I'm at 0.96a, and GCC2.12b. At least with 0.96a Elm reports that it got the
seg violation signal. I recall seeing that being changed in 0.96=>.
I'm at a loss at this point. Others have said they compiled with no problems,
and it is working just great except for that ONE SMALL bug.

You're getting integer division. You want floating point. Try:

I was looking at the keyboard.c code last night, and noticed a small
bug (more of an "oversight" than a "bug"): the ". Del" key on the
numpad produces a "," and not a "." in the num-lock mode on US
keyboards. I changed the appropriate line to make it produce "." on
US keyboards.
I patched this, and added a couple of other things as well:
* a new symbol, USE_ALTGR. If this is defined, the right ALT key on
extended keyboards has the ALTGR function (in other words, it does
what the code does now). If you #undef it, it causes the right
ALT key to behave exactly as the left one (let you switch VC's,
lets you use it as a meta key, lets you enter extended chars on
numpad, etc.
* a new symbol, ALLOW_KBD_RESET. If this is defined, CTRL-ALT-DEL
will reboot. If it's #undef'ed, CTRL-ALT-DEL will not reboot.
* a new symbol, SHOW_SCRLED. If this is defined, then the SCROLL
LOCK key will cause the appropriate LED to light. Since this key
doesn't actually toggle a key state (shows process info instead),
I find this annoying so I #undef this symbol. I that case, the
LED never lights.
* a new symbol, CAPS_TO_CTRL. If this is defined, then the CAPS
LOCK key behaves as another CTRL key instead of a CAPS LOCK key.
I never use CAPS LOCK, and I find its location to be more
comfortable as a CTRL key, so I #define it.
Following are the patches. I hope you like them. I make no warranty
on them whatsoever. 🙂

I started off by saying "c" in kermit.
He said "set line first". So I set line /dev/ttys1.
Next, when I tried "c", he said "can't open lock file". So I created
directories /usr/spool/{uucp,locks}.
Next, when I tried "c" he froze.
I was logged in as root on two virtual consoles, and there should have
been a getty on two more. Alt-F* worked; I was able to switch from
one screen to another. ScrollLock and Ctrl-ScrollLock worked. Nothing
else worked -- the kermit was frozen, ^C or ^Z did not affect it,
the other login session was frozen, the two gettys would not let me
login.
I waited for 30 seconds hoping update would do his stuff and did a power
out. fsck on both /dev/hda1 and /dev/hda2 does not complain, so I have
no hard disk damage?
Q1: What does one do to make kermit work right?
Q2: A good Unix should not let this happen. I'm no kernel hacker, but
what information should I pass on to the folks who are?
-ans.

I have downloaded the bootimage-0.96a and rootimage-0.95a files. I am
able to mount the filesystem on my scsi disk, but I cannot get it to
boot. I got the scsi 'fdisk' program and am able to mkfs and mount the
file system. I did a mknod /dev/sd1 b 8 17, second scsi drive, 1st
partition. The partition is less than 32 meg, as reported from fdisk.
I used the pboot.exe program to set the boot disk, too mount my hd
parition as root. I think that I have entered the hex word for pboot
wrong, what should it be?
I have also read all FAQ's, and README files.

Hi
Linux-0.96a, made from 0.96 source & the 0.96->0.96a patch, compiled with
gcc2.11c .. boots O.K. runs for ~10-12 seconds .. then the keyboard freezes.
takers ?
attempting to 'gcc -s -lm awk.a -o awk' .. get a bunch of 'undefined symbol
ref'd from text segment' for _pow, _exp, _floor, _ceil, _log, _sqrt ..
the shared libs are set up as no 387 (since I have none ;( ...)
that one is from a 2.11a shared *.a's tar .. using gcc2.11c .. most others
compile O.K. .. need awk to get rc to compile.

the adaptec 174x has a 154x emulation mode which seems quite compatible
with the various 154x drivers. if the bustek 74x is as similar to the
adaptec 174x as the bustek 54x is to the adaptec 154x, it will have this
emulation mode and you can just use it. perhaps a call to bustek is in
order?

Actually you only need to cast one of these, "480.0 / 640" would do
the trick.

Message-ID: <[email protected]>
Date: 2 Jun 92 13:03:22 GMT
Organization: SDRC, Cincinnati
Lines: 47
I just recently got X11 v1.0 up and running on my Linux 0.96a system. I was
even able to compile a game (xbattle with gcc2.11c). When I startup X
everything seems to look normal.
Now on to the problem (you knew there would be one:-). My mouse (Logitech
3-button mouse) is working but is VERY hard to control. When I try and move
the cursor around the screen it is VERY jumpy. Also if I move the mouse over
my xterm window, it appears to be sending button clicks when I am not
pushing any of the buttons. It appears to be selecting and pasting text into
my xterm window when I move the mouse over the window. If I position the
cursor in the window and do not move the mouse, I can use the xterm and no
problems exists.
I have seen some notes about trying to put the following line in the xinitrc
file but it has not worked:
stty -istrip > /dev/stty1
Has anyone else seen this before? I have read through all the mail and FAQ's
I have but cannot find a solution. I have the normal entries for my mouse
in the Xconfig file. Here it is incase you want to see it:
Logitech "/dev/ttys1"
BaudRate 1200
SampleRate 150
# Emulate3Buttons
I get the same effect if the SampleRate line is commeted.
I have seen some reference to a mouseinfo.c program. Can someone send this to
me if you think it would help?
Even with the above problems I have tried to run xbattle with success. It
makes it very difficult however when the cursor is jumping around the screen.
Thanks in advance for any help you can give me.
P.S. I found a problem in either the X11 includes or GCC includes. When
compiling xbattle, the typedef wchar_t was undefined. I found if I used
-DX_WCHAR during the compile, everything worked fine. Any ideas? Once I
have more information I will send it to X11 and GCC.

No bug. Posix requires du to report 512-byte blocks. You can make it
report 1024-byte (1k) blocks with -k. I have it aliases in my .bashrc
like this: alias du='du -k $*'.

Are you booting off of floppy or the hard disk? If you boot the
hard disk, you will need to use shoelace and laceup on the system,
and will need to install the kernel on the root partition.
8, 17 is the right number for the device.

Just how do most unixes do this? The getty_ps package seems to expect an
entry in utmp before it runs. On the other hand, the standard init (is it
simpleinit.c from poe-IGL?) doesn't touch utmp, and the agetty.c from poe
dumps a utmp entry without checking for an INIT one.
Is it also standard practice for both getty and login to stick an
entry into wtmp? I end up with LOGIN/username pairs.

We *finally* got X386 working on our paradise board with a taxan multisync
monitor. After spending all day (12+ hours) staring at video timings, we
happened to boot up into the 80-column text mode, and type 'startx'. It worked.
I can't remember reading of anyone having mentioned this before - using the
132-column modes can screw your graphics mode registers.
This wasn't just an isolated incident, it happens all the time. Booting in
low-res text is the only solution.

Paul says he doesn't support sysV type systems because he has no access to
them. Hence, zsh is very bsd. Bash is just fine for me - the globbing is
better than ksh, but not as good as zsh. 2.2 *is* much better than 2.1, tho'
- got it running on sequent dynix & sunos. Bash does have an annoying habit
of not being able to pipe output from a function. If you have
ll () { ls -alF $@; }
then ll|more doesn't work, but (ll)|more does. Other functions behave
similarly.

You're lost 🙂 Subscribe to comp.unix.bsd. Be prepared to wade thru
discussions of why is Mach not unix, why isn't a microkernel micro, how to
squeeze preformance out of serial drivers, and some stuff on BSDI's BSD/386,
which like 386BSD also descends from the Berkeley Net/2 source tree. Not a
whole lot on 386BSD right now, since there hasn't been a new release in two
months. The only relationship to linux is that both groups are liberally
'stealing' code from the other to add features & fix bugs.

My chipset is WD90C00 which is in the x386 FAQ.
From x386 FAQ.
4. What VGA boards are supported?
ET3000 (for ex. GENOA 5300/5400)
ET4000 (Tricom, STB PWR Graph, Sigma Legend, etc.)
GVGA (Genoa 6400)
PVGA1A (Paradise VGA Professional)
WD90C00 (Paradise VGA 1024)
Does x386 under linux supoort WD90C00 ?
Thanks.
Well, the problem with these WD90Cxx boards is quite trivial. X386
just follows WD's recommendations that a SVGA board using a WD chipset
is REQUIRED to have a certain id string in it's BIOS. Some vendors
decided not to do this (well, they tried to be like IBM ...). Thus
X386 will not autodetect the chipset.
But on the other hand, nothing prevents you from overriding, the
autodetect mechanism, and explicitely say:
Chipset "PVGA1" (or so)
Again this is a typical RTFM question, which IMHO just wastes network
bandwidth by beeing asked here ...

Hi,
This is more of a bug fix release of mgr. (-V/-v still
reports v0.02 but this is v0.03, I just forgot to bump the rev number)
Anyways, these are the changes from v0.02 to v0.03
Job control/pty/shell tty stuff fixes. (Bash should work now)
Star trek effect fix ([email protected])
new install script to configure mouse and default display
mode.
Turn on 128K TVGA modes utility.
Basically the most important change is the bugfix for the problem of
not being able to use bash under mgr.
Also, I no longer provide with the statically linked "mgr" executable.
You now need to have a working gcc v2.1 or better.
If you are first time MGR user simply get the file
banjo.concert.net:/pub/Linux/MGR/linuxmgr.tar.Z
It contains everything you need to have in order to run MGR. Be sure
you read the README file, since some of the questions in the install
script may seem cryptic.
If you are upgrading from v0.02 to v0.03 and still have the mgr.a and
the driver files get the file
banjo.concert.net:/pub/Linux/MGR/upgrade/upgrade-0.03.tar.Z
extract and execute the upgrade script in the same directory you have
your mgr.a file. Then execute makemgr as root to configure and
create a new mgr executable.
If you want to update your mgr source code, you need:
banjo.concert.net:/pub/Linux/MGR/upgrade/diff-0.03.Z
PS: Distributing files in .a format is great huh? That way you can
release upgrade files instead of full executables.
Please send all bug reports and fixes to me.
If you want better EGA support (i.e. restore text modes) send me
e-mail, I might write a EGA driver but will need somebody to test it.
If you have a new display driver or mouse driver for mgr, please send
it to me.

In fact, if you have execute permission on a directory you can access
files which are in it. But you can't do an ls to find out which file
you want unless you have read access. Someone here created a program
which should really have been setuid, but they couldn't be bothered to
insert the code to swap ids all the time, so they just gave execute
access (only) to the program and to the directory where it kept its
private files. So you couldn't find out the name of the file with ls,
and you couldn't find it by running strings on the person's program,
because that had no read access. It wasn't marvellous but it did seem
to work...
I wonder what happens if you try to ptrace() a binary that is
execute-only?

The code you have written is equivalent to:
scalar = (double) ( ((int) 480) / ((int) 640) );
(I have put the stupid casts of 480 and 640 to integer in to make
clear what is going on)
So you are dividing the integer 480 by the integer 640, giving the
answer 0, and then converting it to a double. What you should do is
either write:
scalar = 480.0 / 640.0;
or else put explicit casts of the integers to doubles:
scalar = ((double) 480) / ((double) 640);

The problems, I had last weekend, to create X11 applications with shared
libraries are solved.
I reinstalled the "old" GCC version 2.11c and deleted all stuff of the
GCC test versions 2.12a, 2.12b and 2.12c on my system and my first X11
test programrun immediately.
This morning I saw, that the above mentioned test versions of GCC were
removed from banjo.concert.net /pub/Linux/GCC, may be that some other
behalve me run into the same problem.

I found the problem.... 🙂
in date.c, function get_arpa_date, I believe, it is wanting to call a
function "timezone" to retrieve the local timezone. Linux's time.h file
defines timezone as an extern long or similar. Well, it seems that when
it tried to execute a function that really wasn't.... Seg error.
Can anyone enlighten me on a timezone function, or if it's in Linux, how
to get to it? For the time being I've compiled it in.

On my system, fdformat works fine on already-formatted disks, but gives
reset-floppy errors and dies on a never-formatted disk. Both 5.25" and 3.5"
disks.

That's no problem, that's absolute correct C behaviour.
What happens is:
480 is divided by 640, but since both 480 and 640 are integers, the /
is an integer division, so you get 0. Then this zero is converted to
double and this gives your 0.00000.
So you should use
scalar = 480.0 / 640.0;
That will do it.
Hope that helped you,
Michael

If X is BSD, MGR is V7. If X is the Cadillac, MGR is the VW. Building
X takes hundreds of megabytes of disk, although you can get by with
much less if you're selective and practice some tape-swapping.
(And, if you don't mind not having sources, you can have a working
basic X setup in 10Mb or so.) Building MGR only needs about 10Mb or so
for the whole thing. X has resources, and zillions of applications,
and multiple toolkits, and industry-wide battles over GUI
look-and-feel. MGR has never heard of a "resource file", comes with only
a smattering of clients, has no toolkits, and is massively ignored by the
industry titans who worry about look-and-feel. X is complex. MGR is simple.
MGR provides multiple overlapping resizeable windows, each of which
can display both text and graphics. Text can be cut and pasted between
windows. An application running in a window can control the font used
to show text, select which events it wants to hear about, iconify itself,
etc. MGR has a simple mechanism for creating and using pop-up menus.
MGR uses the same client/server arrangement used by X, but MGR
can work over any reliable byte-stream without knowing anything about
the underlying protocol. I have an MGR client on my Sun at work that
gathers NFS statistics and produces a moving strip-chart. I can run
this client while logged in from home over a 2400 baud modem, and the
graphics work fine. I currently run MGR on my 4Mb 386 under Minix, and
have enough memory for half a dozen windows. (Minix doesn't have shared
text, shared libraries, or paging, so MGR may do a little better under
Linux.) I have a Trident-based SVGA card. Text scrolling is, well, slow.
It's possible that some work on the bitblt code will help this, but I
think the real fix is to buy a better card. The X folks all seem pretty
happy with their ET4000's.
|I would LOVE to run windows under Linux if possible, but since I am

If you're not wedded to X, MGR might be a reasonable alternative.
It has all the basic stuff a window system must provide, but nothing
that's not absolutely essential. Experienced X programmers will probably
find it frustrating.
|ALSO what video cards they will run on will be VERY helpful.
I'm on shakey ground here, but I have a vague recollection that the
Minix port of MGR worked on any video card that could be made to look
like an EGA. It turns out that some VGA modes, including 800x600x16,
put the adapter in a state that looks just like a really big EGA.
Since a hardware vendor would have to go out of their way to make their
800x600x16 mode *not* look like an EGA, it's a good bet that *all*
SVGA's work essentially the same in this mode. The differences would
be in the specific values you need to stuff in the registers in order
to achieve the proper mode. One determines these values with a little
program that puts the adapter in the desired mode and then reads out
the register values. I use 800x600 for MGR under Minix, and that's
about as high as I want to go on my 14" screen.
I hope this helps!

Yes, this is basically a bug (though it's possible to read POSIX as
allowing it). Fixing it is on the to-do list for release 2.4, which
still has no scheduled release date. The problem is that input()
restores the character that was overwritten by the '\0' that terminates
yytext; why it works on the Sequent is a mystery to me.

The only magic characters inside of []'s are: '\', ']', and newline,
so '"' does not need to be escaped (though it doesn't hurt to do so).

Hi all:
I am trying to get an Esprit Systems Executive 10 terminal working on
Linux and I am having trouble getting the termcap together. Does anyone have
control code info on this beast? Or (*gasp*) a termcap entry for it???
A related question: has anyone used the %c format in termcap and gotten
it to work? I need to set the cursor position code to E^Q%p2%c%p1%c (push the
second parameter (col) and output as a char, push the first parameter and
output as a char (row)). This seems rather trivial but the cursor does not end
up in the right spot (micro-emacs scribbles on the MIDDLE of the screen 🙁 )
I can do this manually using echo commands but curses programs barf. Likewise,
termcap entries do not seem to like spaces in them, either literally or in
octal form. This terminal has LOTS of escape sequences with spaces in them. I
have some limited documentation on this beast but need a full list of codes.
Any hints/tips anyone?

omicron.cs.unc.edu:/pub/faith is Rick's preliminary Future
Domain driver, which uses the command() interface. The drawback
of this interface is that it is not interrupt driven, and
processes will not be scheduled during disk access.
I've been told that Rick is done with the interrupt driven driver
that lacks these drawbacks - when this is made available, it will
be incorporated into the SCSI package which will be fed back into
the "stock" distribution.

As far as disk size supported, the SCSI routines support SCSI disks up
to 2 terrabytes in size.
The limitations stem from the Minix filesystem, which has a 64M
limit (you can only have one filesystem per partition),
and the the fact that at this time the SCSI drivers only support the four normal
partitions.
So, until changes are made, you can only use ~256M of it under Linux.
However, I will put in support for extended partitions RSN,
and people are working on alternate file systems.

this is not true under linux. under bsd systems there are two memory
management schemes used which use the disk: swapping and paging. paging
is what linux uses: when there is no physical memory for a page, one
is evicted to the disk (our swap space) to make room. swapping is the
wholesale motion of a process to disk, and is done by the swapper process.
if your process doesn't do anything for a while the system decides its
better to hedge it bets and evict the whole thing to disk, betting on
locality of reference on a process granularity, i guess.
linux simply does paging, using as much swap as is available. if there
isn't any available, the program waits. linus, correct me if i'm wrong,
but this is what i remember when i hacked with it.

Not me. 🙁

>without a driver. *grrr*
Simple. The mouse company is lying when it says it is Microsoft compatible.
The mouse company can produce a mouse driver for DOS that will make it *look*
like a Microsoft mouse to DOS applications, but if the protocol used between
the mouse and the computer on the serial link is not the same as that used by
true-blue Microsoft mice, then it's wrong to call it Microsoft compatible IMHO.
The Linux drivers in X and MGR (among others) need to talk in the protocol
used on the serial link - Linux doesn't have the benefit of a generic device
driver interface like DOS does.
Classic case of "DOS is the only thing that matters" syndrome on the part of
the mouse manufacturers. It's almost impossible to find real information on
the protocols used. 🙁
Anyway, even though I don't have a Dexxa mouse, I'm trying to figure out the
protocol based on what Dexxa people tell me so I can include it in my mouse
library for Linux (which will eventually make it into MGR, and maybe X if
Thomas Roell includes it). I have a test program here that decodes some of
the Dexxa behaviour (mainly the buttons), and I'm looking for people to run
this and send me the output so I can stare at it and figure out the rest of
the protocol for the mouse movements. Please contact me if you want to help
out.
Any technical data on the Dexxa mouse protocol is *very* welcome.
Cheers,
Rhys.

Hello,
as I tried to compile zoo using gcc 2.11c / linux 0.96a & patch1
I got a problem which I tracked down to the following:
when adding a file to an archive zoo first creates an empty directory
entry in the archive, then compresses the file and stores it and then
fseeks back to the position of the directory entry and overwrites it.
This works fine with standard compression.
If high compression is used, the compressed file is not stored using
blocktype read/write operations, but using putc. I inserted an ftell
into the code after the following fseek, which reports the right
position. Nevertheless the following fwrite doesn't go there, but
on the next 1024 bytes boundary. No need to say that this corrupts
the archive.
If this is a bug, is it in the gcc libraries or in the kernel?
Is there any immediate fix? I would like the zoo high compression
to work reliably to use zoo for my backups.
Thanks for 'listening',
Greg

Unfortunately all my sound players and things (I wrote Modplay, and I also
use linux) need to hook the timer interrupt and they reprogram it to run
at many kHz. This isn't something thats going to work or be of use in
Linux.
I was thinking that it would be *really* easy to get a /dev/audio device
to output through sound cards that have DMA - like the Soundblaster (yuk)
and Covox Sound Master etc... I have code that will do DMA but I wouldn't
have a clue how to get a device driver working for linux... anyone interested

The docs have lots of the IBM character set in them - not something to

several hundred k of Modplay,
