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 dete
