Snooper(TM), the System Checker
Copyright 1992, 1994 John Vias

SNOOPER'S REVISION HISTORY

VERSION DATE REVISIONS
3.30* 3/19/94 We have a new address! Please update your records
accordingly. Existing telephone numbers have not
changed, but we have added a dedicated fax line so you
can fax in your order. Our new address and fax line
are:

VIAS AND ASSOCIATES
75 SW 75 ST D5
GAINESVILLE FL 32607-1603

ORDERS: (800) 332-8234 (same as before)
FAX: (904) 332-4951

3.29 3/94 Added the feature you've asked for the most:
Auto-Logging! This command line option
(/A[B/D/E/L/N/O/S]) causes Snooper to log whatever
screens you want, automatically, with no user
intervention. This is perfect for gathering hardware
inventory for an entire network through a login script.
See SNOOPER.DOC for full details about how to use this
powerful feature.
3.28 3/94 Improved modem detection, making it faster and more
reliable.
3.27 2/94 Changed command line switches for increased similarity
with other programs and increased intelligibility. We
held off doing this so you wouldn't have to change
batch files and such, but we thought it was more
important to make this change now and make it easier on
everyone in the long run. If you have a batch file that
calls Snooper, and it used to run fine and now does
funny stuff, you probably need to update the command
line switches as follows. Snooper's help screen
reflects the new switches.

Old switch New switch
/BW /Mono
/Non-interactive /Batch
/MathChipSkip /NDPSkip
3.26 2/94 Added PCI bus detection and the ability to detect and
report both PCI and EISA in the same system.
3.25 2/94 Fixed a bug that improperly implemented file sharing on
networks.
3.24 2/94 In the CMOS screen, when you select a hard drive type,
Snooper will now better report user-defined and invalid
types. You can cycle through 255 types.
3.23 1/94 Removed "Hexium" detection, which returned false
positives on a few machines.
3.22 1/94 Added another command line switch, "/I[DESkip]" and an
associated config file option. This switch bypasses IDE
drive model checking, which a few machines aren't
compatible with.
Added another command line switch "/O[therIRQ]" and
config file option. This switch forces Snooper to use
an alternative IRQ testing routine. It is more
compatible with some systems but tends to be less
accurate, so if the default one works, use it.
3.21 1/94 Fixed a bug in the editor that caused lines containing
tildes ("~") in AUTOEXEC.BAT, CONFIG.SYS, and
SNOOPER.LOG files to display incorrectly. Fixed another
bug that made the cursor disappear after the user
viewed the editor's help screen. Fixed another that
caused the editor's cursor to disappear if you enter
the editor again after saving a file.
3.20 1/94 Fixed Advanced Power Management (APM) detection.
3.19 1/94 Fixed a bug that prevented a few correct license
numbers from being entered. Sorry!
3.18 1/94 Fixed a bug that prevented the automatic use of
monochrome colors on monochrome video cards (MDA,
Hercules, mono VGA).
3.17 1/94 Both MS- and PC-DOS version 3.30 report they are
PC-DOS, so Snooper now reports 3.30 as "MS/PC-DOS
3.30." Also, Snooper will now report PC-DOS 6.10 as
such, even though that version reports itself as 6.00.
3.16 1/94 In reporting fax/modems on the Diagnostics screen,
Snooper will now only report classes over one. So if
you used to see "0,1,2" you will now see "1,2" (the "0"
only means "data modem" anyway, so it's implied).
3.15 1/94 Snooper will no longer automatically insert default
values in the CMOS (memory, date, etc.) if it finds
invalid values or an incorrect checksum. Doing so had
caused problems on a few machines that don't calculate
the CMOS checksum in the standard way.
3.14 1/94 Fixed a bug with the Benchmark screen that caused the
Video benchmark to be reported on the wrong scale if
you returned to the screen after running the benchmark.
For example, it would report 46 on a 100 cps scale
instead of 46K on a 100 K cps scale.
3.13 1/94 If a VESA driver reports the VGA card has 768K, Snooper
will report it as 1M, to avoid confusion.
3.12 1/94 Fixed a bug in the editor that turned the cursor off on
EGA systems. The cursor now stays on.
3.11 1/94 Added more computer types, including a couple Compaqs
and the IBM Thinkpad 750 laptop.
3.10* 11/17/93 Added Netware revision on network screen. It appears as
a letter after the version. Also on the Network screen,
fixed MLID version bug that would cause version 2.01 to
appear as 2.1.
3.09 11/93 Added Current Directory report to Snooper's disk
information.
3.08 11/93 Snooper will now accept long forms for its command line
parameters and switches, making Snooper batch files
self-documenting. It still accepts the single-letter
abbreviations. Because of this change, you may no
longer join command line switches. For example,
"snooper -bq" is no longer acceptable; you would need
to use "snooper -b q." See the manual and Snooper's
first help screen for more details.
3.07 11/93 Fixed the problem that caused Micro Channel systems to
lock up in the Diagnostics screen.
3.06 11/93 In the IDE Model report, if the drive is a Conner
Peripherals, Snooper now removes the word "Peripherals"
so the model name itself is visible in the report.
3.05 11/93 Fixed Pentium detection (it was reporting "Hexium").
Adjusted the Clock Speed report to better differentiate
between 60- and 66-MHz Pentiums (Pentia?). For CPUs
with integrated math coprocessors (i.e., the 486 and
Pentium), Snooper now reports "internal" instead of
"built in" for the NDP report.
3.04 10/93 Added detection of 400 more MicroChannel cards,
bringing the total to over 1,100.
3.03 10/93 On the Diagnostics screen, in the IRQ and DMA lists,
Snooper no longer reports "Reserved" for resources not
assigned to a hardware device. If the resource doesn't
appear to be reserved, Snooper reports "Available." If
the resource has been reserved, Snooper reports "In
use." Also, DMA channel four is no longer detected
because it is used internally and isn't available for
installable devices.
3.02 10/93 Removed CMOS checksum on the Main screen's Extended
Memory report. The CMOS screen will tell you if there
is an error.
3.01 10/93 Added differentiation of DOS versions 4.00 and 4.01.
3.00 10/93 Added detection of Plug-'n'-Play capability to the BIOS
report. This specification allows P-n-P ISA cards to be
automatically configured through software, like MCA and
EISA cards are now.
2.99 10/93 Snooper will now report if the computer has both
MicroChannel and ISA buses.
2.98 10/93 Added detection of several more computer types,
bringing the total to over 110.
2.96 10/93 Added detection of several disk caches to the main
screen. See the manual for details. Had to condense the
Keyboard report slightly, with no loss of info.
2.86 10/93 Oops! For some reason we thought floppy drives used DMA
channel three, when actually they use channel two.
Snooper's display has been updated to reflect this
revelation.
2.85 10/93 Added detection of XGA amd XGA-2 video to Video report.
This will work on MicroChannel bus systems.
2.80 10/93 After exiting the built-in editor, Snooper will prompt
the user to reboot only if changes were made and the
file was successfully saved. Snooper will wait for a
keypress if there was an error saving the file.
Otherwise, Snooper will immediately return you to the
Main Screen. If you choose to reboot, Snooper will
pause in case write-delayed caching is enabled, to
ensure the file is actually written to the disk.
2.78 9/93 Fixed an apparently long-standing bug that prevented
Snooper from recognizing some older IBM models and
others by name.
2.76 9/93 Snooper should less often report gibberish in the "IDE
model" report.
2.75 9/93 Defined default scales for the graphs on the Benchmark
screen, according to CPU type. So, for example, the
default scales for a 486 machine would be higher than
one for a 386. Now, when a machine is so fast it makes
the graph change color, it means the machine is fast
for its class.
2.70 9/93 Added reboot function to allow the user to reboot from
within Snooper after changing the CMOS or CONFIG.SYS or
AUTOEXEC.BAT.
2.68 9/93 Improved Snooper's disk benchmark, adding sequential
reads to the random ones and computing a weighted
score.
2.66 9/93 Snooper should be able to report more information about
a second hard drive, if there is one.
2.65 9/93 Added detection of DOS 6's DoubleSpace drive
compression, reported on the Disk Status line.
2.64 9/93 Added detection of Advanced Power Management (APM) and
its version. It's reported after the computer type.
2.63 9/93 Added detection of the Communicating Applications
Specification (CAS) and FaxBIOS, and their versions.
They are reported on the Diagnostics screen under the
COM port information.
2.62 8/93 Improved VESA video memory detection under VESA 1.0.
Snooper can now report half-megabyte values (e.g.,
1.5M, 2.5M). You may have a bit more memory than
Snooper reports. For example, you may have 2M when
Snooper reports 1.5M. Under newer versions of the VESA
spec, Snooper should always report video memory
accurately.
2.61 8/93 Snooper will now retore the cursor upon exit, and set
ERRORLEVEL to at least 32, if a runtime error occurs
(but that *never* happens!).
2.60 8/93 Added one to the Cylinders report for hard drives. This
should now match what the CMOS reports.
2.59 8/93 Improved error-reporting while trying to save a .CFG
file in Setup screen. Snooper will now report if the
disk is full, an existing .CFG file is read-only, etc.
2.58 8/93 The benchmark graphs now change color if they change
scale, so you can see at a distance that the scale is
not the default. Also, the benchmark graphs are
retained when you return to the main screen and then go
back to the Benchmark screen.
2.57 8/93 Added detection of fax modems, and the classes they
support, on the Diagnostics screen. The new report,
"fax class," will display for example, "0,1" if your
fax modem supports classes zero and one.
2.52 8/93 Removed detection and supression of "fake" Novell
parallel ports on Diagnostics screen. Now you can see
the port status that other programs see, even if these
ports aren't physically present. Also, Snooper now only
looks for three LPT ports, not four.
2.51 8/93 Removed detection of Ballpoint mice because there were
too many false positives.
2.50 8/93 Added beeps to alert you to error conditions (e.g.
invalid drive). This should be helpful especially to
visually-impaired users. When you hear a beep, look at
the message line in the lower right corner to see what
the beep was for. The beeps can be toggled on and off
via the Setup screen.
2.48 8/93 Added Benchmark screen, accessible with (hey,
was already being used!), performs CPU, video,
and hard disk benchmarks.
2.38 8/93 Added Adaptec SCSI host adapter identification. It is
reported on the same line as IDE model would be.
2.37 8/93 Changed the log filename from SNOOPER to SNOOPLOG to
make it consistent with the SNOOPCFG variable (see
below).
2.36 8/93 You can now define a SNOOPCFG environment variable to
designate the configuration file Snooper should read
(e.g. "set snoopcfg=c:\control\johnv.cfg"). Very useful
on networks when set in a login script or in
AUTOEXEC.BAT (don't forget Alt-A will let you edit
AUTOEXEC.BAT!).
2.35 8/93 Added help line on the bottom line of each screen;
removed the much shorter help lines above the message
boxes.
2.32 8/93 Changed the keystroke used to print an invoice from
for Register to for Order, perhaps making it
clearer for some of you.
2.31 7/93 Improved Setup screen's user interface to match that of
the CMOS screen (see below).
2.30 7/93 Added field to allow or disallow CMOS editing. This
feature is for network administrators who want to
prevent knowledgable-enough-to-be-dangerous users from
changing their computers' configurations.
2.29 7/93 Added CMOS configuration viewing/editing screen. Press
from the main screen to see it. If CMOS editing
is allowed (check the Setup screen), you can use the
highlighted letters, and the arrow and Tab keys to move
from one field to another. Once you're on the field you
wish to change, press +/- or PgUp/PgDn to modify that
field. If CMOS editing is disallowed, you will only be
able to view the CMOS configuration.
2.19 7/93 Snooper now searches for ROM BIOS extensions every
256 bytes instead of every 2K, sniffing out more
adapter cards.
2.18 7/93 Snooper can now differentiate between Dell 450DEs and
466DEs. Changed the order form into an invoice. Now
business users can pay for Snooper on a purchase order
and already have an invoice to send to Accounting.
2.17 6/93 Fixed detection of 2.8M drives. It should work now.
2.16* 6/26/93 Fixed minor cosmetic bug in drive list. Also, now you
can press or when changing default
disk drive in Setup screen.
2.15* 6/18/93 Fixed minor bug that prevented you from using cursor
keys to switch from drive A: to the next drive in a
system with one floppy and a hard or network drive.
Snooper no longer displays the B: drive in its drive
list if the system has no physical B: drive.
2.14 6/93 You can now print the display to PRN with .
now logs the system files. still logs
to a file.
2.13 6/93 Added detection of DOS revision level for versions 5
and up. It appears as a letter after the DOS version.
2.12 5/93 Snooper now more-vigorously checks the IDE model for
garbage characters. This line should now be blank for
non-IDE drives.
2.11 5/93 In the editor, you can now restore a deleted line with
. To restore other deleted text (e.g. words),
continue to use .
2.10 5/93 Added network information screen, accessible via
. Currently, this screen provides info only on
Novell networks. See the manual for more details.
Removed the Western Digital network card detection
routine, as it turned out to be the responsible for
Snooper breaking the network connection. Now when you
use the Diagnostics screen on a network, you usually
stay connected.
2.09 5/93 Added detection of Pentium (tm) (and Hexium?)
processors.
2.08 5/93 If your system has more than 19 logical drives, Snooper
now displays them in two rows. Also, the end bracket
immediately follows the last drive letter.
2.07 5/93 Now you can press to indicate "Yes" to "(Y/n)?"
prompts in the editor (e.g. saving the file).
2.06 5/93 Added detection of over 700 MicroChannel adapter cards
via the new Bus Screen. Access it with . See the
manual for more details.
2.05 5/93 Improved detection of network drives. It's accurate
now, but the minimum DOS version had to be raised to
3.10. This shouldn't cause a problem for most of you.
2.04 4/93 Added detection of Toshiba DOS and Olivetti DOS.
2.03 4/93 Added detection of several more Dell computers.
2.02 4/93 Added fifty new computer types, mostly IBMs. Snooper
can now recognize over 100 computers by name.
2.01 4/93 Snooper can now distinguish between LANtastic and LAN
Manager. Added report of PC LAN and LAN Manager
versions.
2.00* 3/30/93 Improved VESA video memory detection. Snooper now
retrieves the memory amount directly from the VESA BIOS
if the VESA version is at least 1.01. Also fixed a bug
that caused the VESA version to be reported
incorrectly.
1.99 3/93 Added detection of a Logitech mouse driver's version.
Also, in the IRQ list on the Diagnostics screen, if you
have a new enough mouse driver, Snooper will report if
it's a TSR loaded in your AUTOEXEC.BAT file
("MOUSE.COM"), or a device driver loaded in your
CONFIG.SYS file ("MOUSE.SYS").
1.98 3/93 Added more rigorous testing to determine if a parallel
port really exists before testing its IRQ and status.
Rearranged Parallel Port Status reports.
1.97 3/93 Expanded configuration file with blank space so we can
add more options in the future while maintaining
backward compatibility with existing .CFG files.
1.96 3/93 Added report of parallel port IRQ. Keep in mind that
many I/O cards with parallel ports do not generate the
IRQ properly. This report uses parentheses like the COM
port IRQ (see below).
1.95 3/93 Added indication of a COM port's IRQ being enabled. If
the IRQ number does not appear in parentheses on the
Diagnostics screen, that COM port's IRQ was already
enabled before Snooper was run. If the IRQ is written
in parentheses, the IRQ is not active on that port.
Also, COM port info is centered now.
1.94 3/93 Added detection of the port address of Western Digital
and compatible network cards, displayed on the
Diagnostics screen.
1.93 3/93 Added an internal text editor for CONFIG.SYS,
AUTOEXEC.BAT, and SNOOPER.LOG files. Added
configuration option for toggling between using the
internal editor or an external one.
1.92 3/93 If you were using only a tiny percentage of a disk,
Snooper may have shown an empty bar graph, perhaps
misleading you into thinking the disk was empty. Now if
any amount of disk space is being used, Snooper shows
at least one block in the graph.
1.91 3/93 Added logging of CONFIG.SYS and AUTOEXEC.BAT files.
From Snooper's main or Diagnostics screens with
and from the command line, with the /P switch. This
feature will copy the contents of both files to the log
file. The switch can be used with or without the
logging switch, /L. It will use the log filename
specified with /L.
1.90 2/93 Changed format of configuration file. Config files made
with earlier versions will be incompatible with future
versions of Snooper, so just delete them and make new
ones.
1.89 2/93 Instead of prohibiting you from invoking Snooper's
Diagnostics screen under multitaskers and networks, now
Snooper just warns about the dangers involved and asks
if you wish to continue.
1.88 2/93 Fixed editor loading routine to correctly load a batch
file called EDIT.BAT by loading a secondary command
processor (e.g., COMMAND.COM, NDOS.COM). Snooper now
ensures the relevant files exist before invoking the
editor. Added a wait for keypress after editing before
restoring Snooper's screen.
1.87 2/93 Reassigned editing keys: loads only CONFIG.SYS,
and loads only AUTOEXEC.BAT. Using for
this feature forced us to change the (Advanced)
Diagnostics key to for Diagnostics.
1.86 2/93 Improved Setup screen's readability by aligning default
options and changing the choices from Yes/No to
Yes/Auto.
1.85 2/93 Reversed action of PgUp/PgDn, Up/Down, Left/Right in
help screens and main screen to make those keystrokes
more in line with convention. Pressing PgUp will now
move you, for example, from page three to page two of
the help screens, or from drive B: to drive C:.
1.84 2/93 Added logic to guess where a mouse is located even if
the normal detection routine doesn't find it.
1.83 2/93 Redesigned Diagnostics screen, added message area and
help line consistent with main screen.
1.82 2/93 Redesigned setup screen; added mono- and Desqview-mode,
and default disk drive as setup options.
1.81 2/93 Improved detection of COM ports, COM port IRQs, and
modems.
1.80 2/93 When the log file-viewing feature is invoked, it now
checks for the existence of a log file before loading
the editor.
1.79 2/93 Integrated SNCOLORS into SNOOPER.EXE. To change
colors, enter a license number, etc., press in
Snooper. Changes will take effect the next time you
run Snooper.
1.78 1/93 Streamlined volume label detection. Reorganized
DOS shell routines to make them more portable.
1.77 1/93 Corrected XMM detection bug present in version 1.76.

1.76 12/92 Added improved CPU speed benchmark. It should be much
more accurate now.
1.75 11/92 Added (Advanced) Diagnostics screen via . The
AD screen shows you:
* Active IRQ levels (0-15)
* Active DMA channels (0-3)
* Sound card address
* Parallel port addresses and status (busy, paper out,
I/O error, selected)
* Serial port addresses, UART (8250-16550A), FIFO
buffer status (on or off), port speed, data bits,
parity, stop bits, IRQ, and device attached (modem
and/or mouse)
1.74 10/92 Added on-line viewing and editing of SNOOPER.LOG via
external editor. To use this feature, press at
Snooper's main screen. See editor-naming requirements
below.
1.73 10/92 Added on-line editing of CONFIG.SYS and AUTOEXEC.BAT
via external editor. To use this feature, press
at Snooper's main screen. The editor must be
named EDIT.COM, EDIT.EXE, or EDIT.BAT, and it may
reside in the current directory or on the path.
"Ed-It!" version 3.0 (a public domain editor, included)
will open both files at once in separate windows.
Other editors may only open CONFIG.SYS. You can open
AUTOEXEC.BAT with their editors' Open File command.
1.72 10/92 Added on-line registration feature. Press "F1" for
help, then "R" to print an order form. You will be
asked what port to print the form to.
1.71 10/92 Snooper now shows you all valid drive letters, right
next to "Disk." The current drive letter is
highlighted and capitalized. The Volume Label report
was moved down; it's now the first disk report in the
column. Due to limited screen space, the Total
Clusters report was removed (CHKDSK can tell you if you
really need it).
1.70 10/92 Added detection of Oak VGA cards.
1.69 10/92 Improved detection of Genoa VGA cards; Snooper should
now recognize more models.
1.68 10/92 Added detection of Logitech 6.10+, Mouse Systems,
Genius 9.06, and Z-NIX 7.04d mice by name. These may
work with earlier and/or later driver versions than are
specified here. Rearranged Mouse report slightly.
1.67 10/92 Added ability to paste Snooper's display to the Windows
clipboard using Shift-Delete. The display is pasted as
text.
1.66 9/92 Snooper now gives up its timeslice under Windows, the
DOS-5 task switcher, etc., instead of constantly
updating its time display (just press the spacebar for
an update).
1.65 9/92 Added timeout for IDE model routine to avoid locking
system. Fixed bug that failed to report certain
computer types by name.
1.64 9/92 Added detection of VESA version. Fixed bug that caused
256K VESA VGAs to report 3K.
1.63 9/92 Fixed bugs that caused lockups on 286s with math chips
and possibly others (sorry about this one!).
1.62 9/92 Added Stacker detection and version to Disk Status
report.
1.61 8/92 Added report of A20 status in HMA report.
1.60 8/92 Suppressed IDE model detection under Windows 386
enhanced mode (conflicts with 32-bit hard drive
access).
1.59 7/92 Removed the necessity of having MSCDEX.EXE 2.x to
detect CD-ROM drives. Now Snooper can detect CD-ROMs
with any driver version.
1.58 5/92 Added detection of Tandy 1000s and Epsons
1.57 5/92 Added IDE Hard Drive Model report.
1.56 5/92 Added detection of DOS buffers, including look-ahead
buffers.
1.55 5/92 Added detection of DOS files.
1.54 5/92 Removed registration reminder box in lower right
corner, freeing screen space for more disk reports.
Added space for messages such as "Invalid drive,"
"Writing log file," etc.
1.53 5/92 Added detection of CMOS hard drive type.
1.52 4/92 Changed the logging keystroke to Alt-L to allow you to
access drive L: directly.
1.51 4/92 Replaced the Adlib detection routine with the official
one, probably fixing the false detection bug.
1.50* 3/30/92 If Snooper detects that a VGA adapter has more than
256K of memory, it will report it as SVGA.
1.49 3/92 May have fixed UMB report under DR-DOS 6.
1.48 3/92 Implemented two-tiered shareware registration.
1.47 2/92 Added detection of PS/2 models 35, L40, 55LS, 57, M57,
65SX, 90, and 95 and of the PS/1 model 2121.
1.46 2/92 Fixed bug that caused incorrect used Conventional
Memory report when Snooper is loaded into an UMB.
1.45 2/92 Removed detection of 80186/88 CPUs for greater
stability.
1.44 2/92 Improved disk type checking; Snooper recognizes 2.88M
floppy drives. Floppy drives with no disks in them
will now report the drive type anyway.
1.43 2/92 Added ability of sequence keys to skip invalid drive
letters. Now you can press to go from drive C: to
drive E: if you have no drive D: (you used to have to
use letter keys to access noncontiguous drives).
1.42 1/92 Added logic to detect invalid command line entries,
which cause Snooper automatically to show the invalid
characters on its syntax help screen.
1.41 1/92 Added Desqview mode switch, /D, to force Snooper to use
the BIOS when writing to the screen. Snooper normally
detects Desqview and switches to this mode
automatically but some of you may want to use it for
other environments.
1.40 1/92 Expanded Mouse report to always show serial plus the
COM port or IRQ level.
1.39 1/92 Implemented better game port detection. It should work
on AT class machines now. Also fixed minor bug that
caused the 01/10/84 IBM PC-AT not to be reported by
name.
1.38 1/92 Fixed minor bug involving incorrect IRQ levels reported
by a certain mouse driver. Fixed minor bug that caused
the mouse driver minor version to be reported
incorrectly.
1.37 1/92 Expanded single help screen to three, to show command
line syntax, keystrokes allowed in the program, and
shareware information.
1.36 1/92 Fixed math coprocessor detection lockup bug. This may
have been the lockup problem, even though we blamed the
CPU detection routines. The /C and /M switches finally
may be obsolete. (We hope, but let us know!)
Implemented improved RAM disk detection logic.
1.35 1/92 Included Sncolors, a utility to change Snoopers colors,
in shareware version.
1.34 1/92 Fixed display of percent of used disk space, which
occasionally showed two decimal places.
1.33 12/91 Reduced memory use to 85K, making Snooper easier to
shell to from another program under cramped memory
conditions (aren't they all?).
1.32 11/91 Implemented detection of Sound Blaster, Adlib, and
Roland MPU-401 sound cards.
1.31 11/91 Added shell version for Novell networks, version for
Lantastic.
1.30 11/91 Added new switch, /M, which disables NDP (Math chip)
detection. The /C compatibility switch now disables
only CPU detection and may no longer be needed. If you
are having lockup problems with Snooper, specify both
of these switches, then one at a time, until you find
the one that will avoid the lockup. Most of you
needn't worry about this at all.
1.29 10/91 Added reports of serial and parallel port addresses.
1.28 10/91 Snooper will find its display (which it needs to in
order to log it) even if it has been moved via the
Relocatable Screen Interface Specification used by
Desqview, Topview, and Memory Commander.
1.27 10/91 After Snooper runs, it should now reset the cursor to
the same shape it was originally, not to a default
shape.
1.26 10/91 Rewrote CPU and NDP detection routines in BASM (TP 6's
built-in assembler), making them more stable.
1.25 10/91 Added detection of several more computers by name.
Added report of DOS-5s location, if in HMA or ROM.
1.24 10/91 Fixed Windows 386 Enhanced mode detection. Problem was
caused by the way Turbo Pascal calls interrupts (or
not).
1.23 10/91 Command line arguments may now be combined (e.g.,
snooper -bc:n is OK).
1.22 10/91 Uses BIOS screen writes if it detects DESQview and also
corrects a DESQview detection bug.
1.21 10/91 Implemented file sharing on networks. Added detection
of several Dell computers by name.
1.20 10/91 Added detection of NDOS (and its version and shell
depth), and of OS/2 1.x and 2.x.
1.19 9/91 Added report of largest UMB if EMM386.EXE is loaded and
DOS=UMB is in CONFIG.SYS.
1.18 9/91 Added detection of DOS Protected Mode Interface (DPMI),
Virtual Control Program Interface (VCPI), and ANSI
device drivers.
1.17 9/91 Rewrote screen display routine to draw screen faster.
Changed shareware offer and price.
1.16 9/91 Added detection of several VGA chipsets and, for some,
VGA memory above 256K.
1.15 9/91 Added detection of virtual 86 mode, allowing us to
remove the /3 compatibility switch (Snooper now
automatically skips 386DX/SX detection if CPU is in
virtual 86 mode, avoiding error messages and lockups).
1.14 8/91 Implemented detection of CD-ROM drives if you are
running MSCDEX.EXE 2.x or higher.
1.13 8/91 Implemented improved disk type logic (Snooper now may
recognize some RAM disks and Bernoulli drives).
1.12 8/91 Added detection of video memory installed on VESA
cards.
1.11 8/91 Added check for CMOS validity before asking it for
extended memory installed. Snooper shows a question
mark if the CMOS appears invalid but shows extended
memory reported by the CMOS anyway.
1.10 7/91 Added detection of several brands of ROM BIOS.
1.09 7/91 Employed BIOS date to help detect computer type so some
IBM pre-1987 types, some Toshibas, more Olivettis, and
a few others are identified explicitly.
1.08 7/91 Changed /C switch: /C(ompatibility mode) now disables
all CPU/NDP detection routines. If Snooper locks up
your machine, try using this switch.
1.07* 7/4/91 Added detection of VESA VGA cards and of highest drive
letter on keystroke help line (instead of static A-Z).
1.06 6/91 Added report of extended memory installed according to
CMOS; added recognition of DR DOS, the ATT 6300,
several Olivetti models, and more PS/2s. Corrected
logical bug that prevented several shells from being
reported. (Oops!)
1.05 6/91 Added detection of Weitek 1167 math chip and HMA use.
1.04 5/91 Implemented Compatibility mode to avoid lock-ups on
some PCs running under Windows 386 enhanced mode.
Added logic to detect 486SX.
1.03 5/91 Fixed EISA detection bug.
1.02 5/91 Fixed 486 detection bug and 386/486 lockups; detects
80386SX.
1.01 4/91 Expanded mouse report to show COM port number if
serial, based on default IRQs.
1.00* 3/30/91 First real shareware version. We released a
pre-release version (1.01--Hmm) to a local BBS in
February 1989.
