- I am upgrading a program that uses CGA 320x200 4 color graphics mode. I do not
- want to add true EGA or VGA graphics because of the dated and chaotic
- programming environment :-). I just want to save users from the standard
- CGA pink/cyan/white palette (the other standard CGA palette doesn't work on
- many SVGA cards).
-
- Is it legal to change the CGA 4-color graphics mode palette using the EGA
- setpalette BIOS function? That is, will it work with most VGA compatible
- cards? I have already checked Trident 8900 and ET4000 based SVGA cards, and
- they seem to work fine. The result is actually suprisingly good, using a
- red monochrome palette of black, dark red, light red and white, and other
- monochrome palettes.

- If you post a reply, please send me a copy by email or I might miss it.
