I've taken down the possible resolutions you can squeeze out of an S3-805
(which is an older model than the Trio32 or S3-732) which is from the
XF86Config file on a Linux computer with a multisync monitor (ADI 4GP):
# 640x400 @ 70 Hz, 31.5 kHz hsync
# 640x480 @ 60 Hz, 31.5 kHz hsync
# 800x600 @ 56 Hz, 35.15 kHz hsync
# 1024x768 @ 87 Hz interlaced, 35.5 kHz hsync
# 640x480 @ 72 Hz, 36.5 kHz hsync
# 800x600 @ 60 Hz, 37.8 kHz hsync
# 800x600 @ 72 Hz, 48.0 kHz hsync
# 1024x768 @ 60 Hz, 48.4 kHz hsync
# 1024x768 @ 70 Hz, 56.5 kHz hsync
# 1280x1024 @ 87 Hz interlaced, 51 kHz hsync
# 1024x768 @ 76 Hz, 62.5 kHz hsync
# 1280x1024 @ 74 Hz, 78.85 kHz hsync
# 1280x1024 @ 76 Hz, 81.13 kHz hsync
My experience with S3 cards is only with 805 and 764 (Trio64) but at
least as far as Windoze 95 is concerned, an S3-732 and S3-764 are the
same (same driver). The Trio64 with a PCI interface I must say is
*extremely* fast (on a Pentium-100 running XFree86/Linux the subjective
speed for single-user operation is greater than an SS20 (50MHz
SuperSparc) with a CG6). Not to mention the level of Linux support is
better -- I couldn't get the hiColor modes to work with XFree86 on the
805, but it's ok on the 764. Note these are noname clone cards, with the
generic XFree86 driver, not Diamond or Elsa or something.
