Because I didn't have any documentation that told me that wasn't the right card to use?
Anyway, I was able to install it (using the 864141b5.zip driver) by installing as VGA and then doing setup after that to set it to S3 at 64K colors. It refused to install as S3 directly.
This still gives me problems, however:
1) Dosbox won't scale the screen. In particular, if I select a 64K color mode or a 32K color mode, and run Dosbox in fullscreen, it gives me a tiny 640x480 section in the middle of the 1280x1024 monitor. The Windows splash screen will properly scale (by a factor of 2). Dos games will also properly scale. Windows will scale *if* I choose VGA or 256 color S3, but it won't scale if I choose 64K color S3. It looks strange when I start Windows because the splash screen comes up, properly scaled, and then Windows itself comes up without scaling. I'm wondering if this has anything to do with Windows at all--does Dosbox scale with 64K color mode at all?
Relevant Dosbox settings are:
fulldouble=true
fullresolution=1280x1024
windowresolution=640x480
output=overlay
...
machine=svga_s3
...
aspect=true
scaler=normal2x
2) Playing Daedalus Encounter requites Quicktime. It comes with Quicktime 2.01. Quicktime 2.01 looks like it's installing, then tells me that isnatllation is incomplete and I should delete any files that were copied. Checking windows\system shows me that even though it gave me a progress bar showing that files were copied, no files were actually copied.
I see that someone else was able to install this under No sound with Daedalus encounter and am wondering what I did differently.
I finally managed to install it by getting a newer version (2.12)--for some reason it gave me problems once, but when I started from scratch I was able to get it to work with the game.
3) I now get the same problem described in the earlier message: errors about mmSound.
