Known problems and workarounds.
* A good starting place for troubleshooting is to make a plain DOS bootable
floppy (format a: /u /s), and boot with this. If VPIC now works OK, then one
of your TSR's (mouse, print screen, memory manager, etc) is probably inter-
fering. Rem out all the TSR's in autoexec.bat and config.sys, and then start
puting them back (remove the rem's) one at a time until you find the culprit.
Your video board may also have a VESA TSR you have to run (to enable VESA
info) before running VPIC. If this is the case, you probably want to run this
program in AUTOEXEC.BAT.
* For OS/2 users, set your DOS session to 'Full Screen' and all video
selections to ON except for 'fastpaste'.
* VESA boards. If you have a board which support VESA, but doesn't seem to
work correctly (all modes not there) it may be your memory manager which
is confusing VESA. Make a system floppy as above and boot from the floppy in
drive A and then try to run VPIC. If it now works correctly, it's probably
your memory manager. You should exclude the regions from B000-BFFF (if you
run windows) and C000-CFFF (video BIOS). You may also have to disable
Stealth mode if you are using it. Some cards didn't implement VESA correctly
(older S3 cards and others don't return the correct info when interrogated),
so for these you can configure with the VESA config file, and do 'vpic /v'.
See below about S3 and Tseng VESA implementation.
* Trident TVGA 8900c VESA says it can do 640x480 and 800x600 in 64K colors
without a Sierra DAC. Use Alt C from menu and select 1 (256 colors) for
proper Targa viewing. Also, you can configure with the TRID8900 config file
and do 'vpic /v' from DOS to ignore VESA.
* Older S3 boards (Orchid Fahrenheit 1280 and Diamond Stealth) return wrong
bytes/line and mode attributes. Use 'vpic /v' to call VPIC.
* All ATI boards: ATI will not enable the 800x600 mode unless you pick a
monitor in their SETUP program that is capable of doing the 800x600 mode.
I had to use a custom configuratoin to get the 800x600 mode to work.
* ATI Ultra/8514: You have to run ATI's HDILOAD TSR program to enable the
8514A interface once before running VPIC.
* ATI Ultra Pro supports VESA in all but the hi_color modes. Since ATI doesn't
support them thru VESA, VPIC doesn't support them.
* The Diamond Viper comes with a TSR program (vprmode) which makes the board
emulate VESA, and must be run before running VPIC. Run 'vprmode vesa' either
in your AUTOEXEC.BAT file, or before running VPIC. The Viper also does not
make a vertical sync (per the IBM spec), so 'animate' while viewing doesn't
work.
* The IBM ThinkPad 700c has a VESA.COM TSR program you must run once to enable
VESA before running VPIC.
* The Matrox boards come with a TSR program called MGAVESA.COM which makes the
Matrox look like a VESA board. You should run this before running VPIC.
* The Tseng VESA 1.2 seems to have a problem reading data from the screen.
Configure for the TS4000 (comes this way), TS4000HI or the GENO7900 if you
have hi-color, and do 'vpic /v' to make VPIC not use VESA. Symptoms are
smearing of the mouse and pictures convert wrong.
* Newer S3 boards say they are VESA ver 1.2, but are really VESA ver 1.1.
S3 is correcting for new BIOS (4-93). Workaround: Use S3NEW.CFG and edit to
conform to the modes your card will do. Then, configure VPIC with the S3
config file and do 'vpic /v'. This applies to the following (and probably
more) cards:
