- David,

- Sorry to be the bearer of bad news, but it appears that these drivers
- will only run properly on boards with 1024K (1 meg) of memory. If you want
- call it a *bug* in the drivers, I won't argue.
-
- Even after you upgrade to 1024K things won't be right until you edit
- SVGADATA.PMI by hand (see my posting from last Friday). Personally, I think
- that having SVGA.EXE generate register settings on the fly by reading the board
- (this is what it appears to do -- I have no specific knowledge of this)
- is more trouble than it's worth. It's too easy to end up with sub-optimal
- register values and it's difficult to customize your setup for specific
- monitors. It would seem more reliable to have SVGA.EXE identify the
- board type and configuration and then query the user for things like
- the desired refresh rate and set the appropriate values from an internal
- table.
