TITLE: DR DOS 6 Sample Configuration Files
DOCUMENT ID#: FYI-M-1113
DATE: 07SEPT92
PRODUCT: DR DOS
PRODUCT VERSION: 6.0
SUPERSEDES:


These are some sample configuration files to help you deceide how
best to set up your system. It is not necessary for you to use them
exactly as written but they can be used to give you ideas on what
can be done with DR DOS 6.0. What your computer can actually
accomplish is dependent on the hardware of your system.

These files will setup an XT-type computer to use the following DR
DOS 6.0 features:

The DELWATCH command is a 5k TSR loaded to keep track of deleted
files. The options indicate that Drive C: will be watched and no
more than 200 deletions will be tracked.

The DISKMAP command takes a snap-shot of Drive C:'s file allocation
table. In the instance of serious disk or file corruption problems
this feature will aid in the recovery of your disk and files. This
command, however, can be executed as many times as needed during
your computing session in order to get the most recent FAT image
(via the $x variable in PROMPT, see page 294 of the DR DOS manual).

Depending on the use of this type of configuration, this PC/XT
could be used for other "light-duty" services on networks, et
cetera, and therefore, other drivers can be implemented which would
take more conventional memory such as SuperStor'ing the hard-disk
for additional document storage for a printer server. SuperStor
would take about 50K of conventional memory to run, and could have
a serious impact on the ability to run some DOS applications. The
examples for SuperStor in this document are for drives other than
C:. If C: is compressed SuperStor will create a DCONFIG.SYS file on
the uncompressed side and will place the SuperStor driver there.
Refer to Document 1200 for more information on SuperStor.

An XT-type computer, with LIM 4.0 expanded memory, will take
advantage of the following DR DOS 6.0 features:

First, the computer's expanded memory driver is loaded (named
REMM.SYS in this example). The driver supplied with your computer
will probably be named something different, however, specify the
use of this driver in the same location.

Second, the MemoryMAX driver HIDOS.SYS allows the operating system
to relocate into Upper Memory via the /B=AUTO switch. The other
switches, /CHIPSET=EMSALL or EMSUMB, allow either all the Upper
Memory (128K) to be used for the operating system's purpose (but
with no LIM support) or to allow an EMS page frame (LIM support)
and an Upper Memory Block of 64K. The EMS memory manager and
hardware must be LIM 4.0 compatible for this to properly work.

The Compressed Disk driver, SSTORDRV.SYS, could be used to access
leftover disk space on another fixed disk partition.

The DELWATCH command is a 5k TSR loaded to keep track of deleted
files. The options indicate that Drive C: will be watched and no
more than 200 deletions will be tracked or saved. The DISKMAP
command takes a snap-shot of Drive C:'s File Allocation Table and
will further increase chances of a successful file "undeletion".

This basic setup is similar to an XT with 640K RAM and additional
LIM 4.0 expanded memory.

The LIM 4.0 Expansion Board will come with a device driver which
enables it to work and function with DOS applications. The device
driver that the memory expansion board comes with could be named
REMM.SYS. Please read your documentation for your memory expansion
board for the location and name of the driver that enables that
memory. If the driver supplied with your computer is named
differently, you can still specify the use of this driver in the
same location as indicated by the REMM.SYS line above.

The MemoryMAX driver HIDOS.SYS is allowing the operating system to
relocate into Upper Memory via the /B=AUTO switch.

The other switches, /CHIPSET=EMSALL or EMSUMB allow either all the
Upper Memory to be used for the operating system's purpose or to
allow an EMS (LIM) page frame as well as an extra portion of upper
memory for the operating system to use. As stated earlier the EMS
memory manager and the LIM hardware must be LIM 4.0 to work
properly.

The DELWATCH command is a 5k TSR loaded to keep track of deleted
files. The options indicate that Drive C: will be watched and no
more than 200 deletions will be tracked (the tracked being saved in
a hidden file of the same drive). The DISKMAP command takes a
snap-shot of Drive C's File Allocation Table.

This basic setup is similar to an AT with 640K except for the
/B=FFFF option with HIDOS.SYS. An AT with 1MB ram will have 384K of
extended memory. This 384K will be addressed beginning at FFFF not
A000 (640 decimal) as would be assumed. Because the beginning
address is FFFF HIDOS.SYS can make use of the HMA to relocate DR
DOS kernel and data structures. This has the added benefit of
permiting the more efficient use of Upper Memory for TSRs. In short
up to 192K of memory can be put to use outside of conventional
memory.

286-Based Computer with Special Chipsets and Extended
Memory

SHELL=C:\COMMAND.COM C:\ /P /E:256

These files can be used if your 286/AT has been manufactured with
special memory mapping chips which offer control of certain memory
functions (page 418-423). These systems offer favorable Upper
Memory support for DR DOS's MemoryMAX software to enable and use
Upper Memory for TSR's and device drivers. Shadowing should be
enabled in the computer's CMOS to support the creation of upper
memory by DR DOS 6.0. The important line in this example is the
MemoryMAX driver HIDOS.SYS. This allows the operating system to
sense the type of chipset within the 286/AT, enable Upper Memory
and relocate the operating system files into Upper or High Memory
via the /B= switch.

The valid switch options for HIDOS.SYS /CHIPSET= are:

EMSALL
or (for 286s with LIM 4.0 compatible hardware/drivers
EMSUMB so not applicable in the above example)

NEAT (for 286s with Chips & Technologies NEAT, NEATsx,
LeAPSet, or LeAPSetsx)

SCAT (for 286s with Chips & Technologies SCAT chipset)

RAM (for permanent Upper Memory. Must be used with
the /USE option on the HIDOS.SYS driver)

NONE (for telling HIDOS.SYS not to use Shadow RAM)

AUTO (for AUTO detection of chipset installed)

DISKMAP C:
:DRDOSEND

This configuration will allow a 386 or 486 based computer to
relocate the operating system into High Memory.

IMPORTANT:
EMM386.SYS can be used on some systems but the majority of
computers will not have any extended memory, which is required by
EMM386 in order to create Upper Memory. HIDOS.SYS is used instead
because it does not create Upper Memory with the switches indicated
in the above example.

A NOTE ABOUT HOW UPPER MEMORY IS CREATED ON A 386
In the example for a 1 MB 286 it was indicated that there was a
break in RAM between A000 (640K decimal) and FFFF (1MB decimal).
The 384K above 640K actually began at FFFF and not A000. This is
not quite the case with a 386 computer. In a 1MB 386 all RAM is
contiguous from 0 - A000. However, the additional 384K is usually
reserved for use of memory mapping support chips. What EMM386.SYS
does is go through Upper Memory Addresses looking for ROMs, Shadows
or other devices. It then determines how much free unused space
exists between these used blocks of memory and remaps XMS memory to
fill these spaces. In fact, the technical definition for the Upper
Memory created by EMM386 is XMS-UMBs. This is also why a MEM /A
report will indicate a reduced amount of available XMS when using
EMM386 to create Upper Memory compared to when Upper Memory is not
created by using a /W on EMM386. The missing amount has been used
to create Upper Memory plus a small amount for overhead. Because of
this remapping of XMS memory it is not possible for EMM386.SYS to
create Upper Memory on a 1MB computer.

The SuperStor driver is useful in doubling the apparent capacity of
the disk partition to which it's applied. If this has not been
applied to your disk drive, you can elect not to use this driver
and therefore save a substantial amount of conventional memory.
Therefore, the "?" allows the driver to be loaded at will, whenever
that particular partition needs to be accessed. If the driver is
loaded, you can expect to achieve about 603K of conventional
memory. The above example is for a drive other than C:. If C: is
compressed SuperStor will create a DCONFIG.SYS file on the
uncompressed side of the drive and will place the SuperStor driver
there. Refer to Document 1200 for more information on SuperStor.

This configuration will allow a 386 or 486 based computer to
relocate the operating system into High Memory. With an average of
120K of RAM in Upper Memory, a portion of the SuperStor driver, the
IPX and possibly the NETX software will also fit into Upper Memory.

The SuperStor driver is useful in doubling the apparent capacity of
the disk partition to which it's applied. If this has not been
applied to your main disk drive, you can elect not to use this
driver and therefore save a substantial amount of conventional
memory. Therefore, the "?" allows the driver to be loaded at will,
whenever that particular partition needs to be accessed. The above
examples have been for drives other than C:. If C: is compressed
SuperStor will create a DCONFIG.SYS file on the uncompressed side
of the drive and will place the SuperStor driver there. Refer to
Document 1200.


386/486 Based Computers with greater than 1 Megabyte of
RAM running TaskMAX

CONFIG.SYS

SHELL=C:\COMMAND.COM C:\ /P /E:512

if "%delw%"=="on" DELWATCH C: /F:200
if "%tasker%"=="on" share
if "%tasker%"=="on" taskmax
DISKMAP C:
:DRDOSEND

This minimal configuration will allow a 386 or 486 based computer
to relocate the operating system into Upper Memory. Although this
is not optimal for the EMM386.SYS driver, the amount of memory
available on most 386/486 computers will allow the Upper Memory to
be addressed and used for the relocation of the operating system
files, drivers or TSR's. With an average of 120K of RAM in Upper
Memory, the operating system will be able to get SHARE into HMA,
and TaskMAX and the Netware drivers into Upper Memory. Before
Netware is loaded you should be able to have 625K available
Conventional Memory. Alternately, you can load the drivers in the
AUTOEXEC file from the command line (eg. SHARE, TASKMAX, HILOAD IPX
and HILOAD NETX).

The NETX utility found on the last DR DOS 6.0 floppy disk is
included to allow you to task-switch on the Network. This will not
allow multiple logins. However, it is designed to allow you to
execute more than one on application on the network.

DISKMAP C:
:DRDOSEND

This basic configuration allows a 386 or 486 based computer to run
WINDOWS 3.0 OR 3.1 in the "Enhanced Mode". The operating system is
being relocated to the HMA (/B=FFFF), and the information in the
video and system BIOS ROMs are being "shadowed" to faster RAM
(/R=AUTO). SuperPCKwik is going to be 2 Megabytes in size (/S:2048)
and use the Extended Memory (/EM) set aside with the EMM386.SYS
driver. It will lend approximately half of its memory for use as
XMS memory for WINDOWS. SuperPCK is using the WINDOWS compatible
portion of its driver (PCKWIN.SYS) so that WINDOWS performance is
enhanced because of better disk performance and will also enable
lending. With the EMM386.SYS driver, an average of 120K of RAM may
be available to relocate network drivers, TSRs and other drivers
into Upper Memory. This configuration has been able to provide 625K
of Conventional Memory before WINDOWS is loaded.

Note:
If the performance of Windows appears to be slow, the cache size
may be too large for the number of applications that are being run
in Windows. This will make Windows run out of XMS memory and it
will have to use swap files. Even with SuperPCK swapping to disk is
slower than running from RAM. Try reducing the size of the cache or
increasing the lending amount.

This same configuration can be used to run Windows 3.1 in Standard
Mode. For Windows 3.0 Real Mode be sure to disable Upper Memory
with the command MEMMAX -U before running Windows.

This basic configuration allows a 386 or 486 based computer to run
WINDOWS in the "Standard Mode" or "real Mode". The EMM386.SYS
driver indicates that NO LIM page-frame be established by the
driver (/F=NONE), the operating system is being relocated to the
HMA (/B=FFFF), and the information in the video and system BIOS
ROMs are being "shadowed" to faster RAM. SuperPCKwik is going to
use all of the extended memory enabled by EMM386.SYS for caching
the disk drive. Half of this amount will be "lent" to Windows.
SuperPCK is using the WINDOWS compatible portion of its driver so
that WINDOWS performance is enhanced because of better disk
performance and will also enable lending. This configuration has
been able to provide 625K of Conventional Memory before WINDOWS is
loaded.

A 2 megabyte computer is the MINIMUM system for Windows in enhanced
Mode. System performance may be greatly reduced because Windows
will need to use swap files and no cache can be used to help
accelerate disk I/O.

This configuration will allow a 386/486 with 2 Megabytes to run
Windows in Enhanced Mode. Because Windows requires a minimum of 1
Megabyte of XMS this configuration does not use the HMA. The SHELL
statement has the switch /ML to force it to Conventional Memory.
EMM386 is not used because it would reduce available XMS memory by
using it to create Upper Memory (See the note for 386/486's with
more than 1MB). HIDOS.SYS is used to create XMS memory but does not
load the kernel into Upper Memory or HMA with /B=NONE and the
statement BUFFERS (Upper) is used instead of HIBUFFERS (HMA).
Finally, because Windows needs all of the XMS memory available
SuperPCK is not used in this configuration.

******************************

MODELS OF CONFIGURATION FILES

The following configuration ideas should be considered advanced and
are for those users who are interested in a more sophisticated
organization of their configuration and autoexec files.

Only the basic ideas are outlined in each example. The rest of the
file can be filled in with your own specifications.

EXAMPLE 1 - The use of GOTO in the CONFIG file.

?"Do you want to run QEMM (y/n)? " goto QEMM
?"Do you want to run MemoryMAX (y/n)? " goto DRDOS

:QEMM
DEVICE=c:\QTR_DECK\QEMM386.SYS
DEVICE=C:\DRDOS\HIDOS.SYS /B=FFFF
(additional QEMM driver lines go here...)
goto COMMON

:DRDOS
hidos=on
DEVICE=C:\DRDOS\EMM386.SYS /F=AUTO...
...

:COMMON
files=40
hibuffers=20
...

The goto statement is used to proceed directly to a label. This
function is similar to that found in batch file processing.

EXAMPLE 2 - The use of CHAIN in the CONFIG file. This example shows
that you can "link" to other files that hold your configurations
for each system "setup". In the following CONFIG.SYS file, the two
lines direct the configuration process to the files: QCONFIG and
MCONFIG.SYS files. The appropriate FILES, BUFFERS, etc. information
is contained within those files and not the main CONFIG.SYS file.

?"Do you want to run QEMM (y/n)? " chain=QCONFIG.SYS
?"Do you want to run MemoryMAX (y/n)? " chain=MCONFIG.SYS


EXAMPLE 3 - The following CONFIG file demonstrates the use of
SWITCH/RETURN commands and use of labels. Select the option by
number and continue processing. Notice the use of the ECHO
statement for setting up the menu options.

ECHO = Choose how much Extended Memory you want to convert
ECHO = to LIM Memory for this session.
ECHO =
ECHO = 1 (or ENTER) No LIM Memory
ECHO = 2 512K of Memory
ECHO = 3 1024K of Memory
ECHO = 4 2048K of Memory
ECHO =
ECHO = Make your selection...

SWITCH NOLIM, 512K, 1024K, 2048K
GOTO DEFAULTS

:NOLIM
DEVICE=C:\DRDOS\EMM386.SYS /F=NONE /K=AUTO /B=FFFF /R=AUTO
RETURN

:512K
DEVICE=C:\DRDOS\EMM386.SYS /F=AUTO /K=512 /B=FFFF /R=AUTO
RETURN

:1024K
DEVICE=C:\DRDOS\EMM386.SYS /F=AUTO /K=1024 /B=FFFF /R=AUTO
RETURN

:2048K
DEVICE=C:\DRDOS\EMM386.SYS /F=AUTO /K=2048 /B=FFFF /R=AUTO
RETURN

:DEFAULTS
SHELL=C:\COMMAND.COM \C: /P /E:512
HIDOS=ON
HIBUFFERS=20
FILES=30
etc...


EXAMPLE 4 - The following CONFIG file section shows how
"environment variables" can be set according to the configuration
options one chooses. These variables are passed to the command
processor (COMMAND.COM) where they can be tested and processed
through the AUTOEXEC.BAT or other batch files. It is not possible
to test an environment variable in CONFIG. The CLS, CPOS, EXIT and
SET commands are featured in this example.

:DEFAULTS
SHELL=C:\COMMAND.COM \C: /P /E:512
HIDOS=ON
HIBUFFERS=20
FILES=30
etc....

ECHO = Choose which TSRs and Utilities you want loaded
ECHO = at BOOT time for this session.
ECHO =
ECHO = 1 (or ENTER) None... just continue
ECHO = 2 Mouse & Cursor Drivers
ECHO = 3 Keyboard "Speeder"
ECHO = 4 Novell Network
ECHO = 5 Done with selections
ECHO =
ECHO = Make your selection...

The accompanying AUTOEXEC below picks up the environment variables.

The AUTOEXEC.BAT file now allows testing of the environment
variables and executes commands based upon the conditionals as
illustrated below:

@ECHO OFF
:drdosbeg
VERIFY OFF
PATH C:\;C:\DRDOS;C:\BATS;C:\TOOLS;C:\WINDOWS
if "%things%"=="on" prompt $e[s$e[0;70H$e[1;36m$t$e[u$e[1;36mDR
DOS6$p$g$e[2;32m
if not "%things%"=="on" PROMPT [DR DOS] $P$G
SET TEMP=C:\TEMP
IF NOT "%TEMP%"=="" MD %TEMP% >NUL
if "%things%"=="on" HILOAD MOUSE
if "%things%"=="on" HILOAD CURSOR /s10
if "%speedkey%"=="on" c:\drdos\mode con:rate=30 delay=1
if "%network%"=="on" hiload c:\lan\ipx
if "%network%"=="on" hiload c:\lan\net3
:drdosend


OTHER EXAMPLES

Select different configuration options from the CONFIG.SYS file
using the ?

?SHELL=C:\COMMAND.COM C:\ /P /E:512
?SHELL=C:\COMMAND.COM C:\ /P /E:1024
?BREAK=OFF
?BREAK=ON
BUFFERS=20
FILES=20
?HISTORY=ON, 256, ON, OFF, OFF
?DEVICE=C:\DRDOS\ANSI.SYS

Select different AUTOEXEC.BAT's from CONFIG.SYS using the ? and the
Shell statement.

In the Shell statement the /P switch can be followed by a filename.
When present, the named file will be executed instead of
AUTOEXEC.BAT. The file needs to have a .BAT extension.

?"Default Autoexec? (y/n) "SHELL=C:\COMMAND.COM C:\ /P /E:256
?"Alternate Autoexec? (y/n) "SHELL=C:\COMMAND.COM C:\
/P:ALTERNAT.BAT /E:256
(Note: There is an 11 character limit including path for the /P:
variable.)

Select and use different configuration files from CONFIG.SYS at
bootup.

?"Do you want to run Windows? (y/n) " chain = WCONFIG.SYS
?"Do you want to use QEMM? (y/n) " chain = QCONFIG.SYS
?"Do you want to use MemoryMAX? (y/n) chain = MCONFIG.SYS
?"Do you want to use 386MAX? (y/n) chain = 386CONF.SYS

(Each line is printed on the screen and you are asked to load/run
the chained configuration file. Each configuration file is a
complete CONFIG.SYS-like file with all appropriate options.)

The idea above can be accomplished by making number-selectable
"menu" choices using SWITCH. Note how the "SET environment"
variables can be used and tested for different "autoexec.bat" files
in this example:

ECHO = 1 For Windows Configuration
ECHO = 2 For QEMM Configuration
ECHO = 3 For DR DOS' MemoryMAX Configuration
ECHO = 4 For 386MAX Configuration
ECHO = 5 For no Configuration... just exit
SWITCH win, qemm, memm, 386m, none
:none

set autoexec=norm
exit

:win
set autoexec=win
chain=wconfig.sys

:qemm
set autoexec=qemm
chain=qconfig.sys

:memm
set autoexec=memm
chain=mconfig.sys

:386m
set autoexec=386m
chain=386conf.sys

Autoexec.bat for the above

@echo off
PATH C:\DRDOS;C:\;C:\UTIL;
VERIFY OFF
PROMPT $P$G
DISKMAP C: D:
IF "%autoexec%"=="norm" goto DRDOSEXIT
SHARE /L:40
IF "%autoexec%"=="win" SUPERPCK /EM /L:2048
IF "%autoexec%"=="qemm" CALL QEMM.BAT
IF "%autoexec%"=="memm" SUPERPCK /A /L:2048
IF "%autoexec%"=="386m" CALL 386.BAT
:DRDOSEXIT

ANSI escape sequences can be used in batch file processing to
create colorful menus. Below is an example of a menu that uses the
SWITCH command and ANSI escape sequences to create a menu. ANSI.SYS
must be loaded in the CONFIG.SYS to allow for cursor positioning
and colors. The first character after the Echo statement is an
ASCII 27 or escape character. This character may be displayed
differently on some printers and monitors (in fact if you have ANSI
loaded you will never see the character when typed to the screen).
To type this character using the DR DOS Editor type CTRL-P then the
ESC key. An alternate method is to type CTRL_Q N and then type the
number 27. Within Editor the ESC character will appear as: ^[ . If
you have downloaded this document from CompuServe or the Novell
Host System the escape sequences have been left intact and you can
use the DR DOS Editor to block out the Echo statements to a file.
If ANSI is loaded then when the file is typed to the screen you
should see white letters on a magenta background.

For additional information on ANSI.SYS and escape sequences refer
to page 399 of the DR DOS Manual.
