Snooper(TM), the System Checker
Copyright 1992, 1993 John Vias
SNOOPER'S REVISION HISTORY
VERSION DATE REVISIONS
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 Advanced 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 I 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
Advanced 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 Advanced
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 Advanced Diagnostics screens with
<Alt-P> 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 the user from invoking Snooper's
Advanced Diagnostics screen under multitaskers and
networks, now Snooper just warns about the dangers
involved and asks if the user wishes 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: <Alt-C> loads only CONFIG.SYS,
and <Alt-A> loads only AUTOEXEC.BAT. Using <Alt-A> for
this feature forced me to change the Advanced Diagnostics
key to <Alt-D> 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 Advanced 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 <Alt-S> 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 <Alt-A>. 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 <Alt-V> 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 <Alt-E> 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. Users 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. I moved the volume label report down; it's
now the first disk report in the column. Due to limited
screen space, I was forced to remove the total clusters
report (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 to the user 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 users 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 <Up> 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 users 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 I was blaming
the CPU detection routines. The /C and /M switches
finally may be obsolete. (I hope, but let me 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 users 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 me 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 user is 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. I released a pre-release
version (1.01--Hmm) to a local BBS in February 1989.
*Denotes publicly-released version
