First off, I finally got Xfree up and running.  Thanks to all that
helped.

Now, I was only able to get it working using my Diamond SpeedStar 24's
(rather slow) clock frequency of 28 MHz.  If I try to set up Xconfig
using the faster rate of 65 MHz (which clock.exe tells me my card
can do), X starts chugging, clears the screen, appears to change
monitor frequencies a few times, and then just goes blank.  It
hangs, and I have to ctrl-alt-del.  I'm using an Xconfig configuration
that should work for my monitor and card.

Here is a listing of my equipment:

Diamond SpeedStar 24 1MB (clocks according to clock.exe: 25.2 27.9 60.8 65.0)
ViewSonic 5E monitor (hor: 31-60 kHz, ver: 50-90 Hz)
Microsoft compatible serial mouse
486/33 motherboard w/8meg ram

Please note that I have gotten X running using the 28MHz clock
setting, but that only allows me to use modes on the order of
640x480.

One thing I've noted is that in order to get the SpeedStar to
use the 65MHz rate, I have to boot to DOS the first time I turn
on my computer, run its VMODE configuration program, and then
boot 386BSD without turning the computer off.  Otherwise the
card will only use the 25 and 28 MHz speeds.

I'd appreciate responses from anyone else with Diamond Speedstar 24's
that have gotten 1024x768 modes working.  (Or from anyone else who
has an idea what's going on :-).
