- 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:
