Is there a list of config settings that OS/2 needs ? I'd like to be
able to give instructions (or an installation script) for different
setups if poss.

Well, I'm using a basic (well, almost - SVGA, but 256K, and no
blitter, etc) VGA card at the minute, although it's an Oak OTI-37C,
so I've got the UniVBE program running, meaning I can forget
supporting non-VBE cards if I have to, but how many cards are there
that have bad or no VBE support still ?
Basically, I want to know that the graphics will be as fast as
possible on a basic card like mine, and a top of the range VESA card
(at least, as much as possible without separate drivers for every
card).
There are a lot of details in the way though, like whether I
should use Mode-X with two pages (under the assumption that the VRAM
access on a good card will be fast enough), so that the card's
blitter can blit straight into the hidden page, or whether to use the
standard "chunky" (non-planar) mode, giving the processor all the work
except the final transfer to the display. I guess you can't use the
blitter for system RAM to system RAM copies can you ?
Hope someone can help...
- Lee.
