Charles Forsyth is correct in noting that 640x480x8 doesn't work
properly. If no one else has figured out why then I'll have a look
when some more pressing matters are resolved.

The following is better, but the cursor problem has me stumped.
All the register values look correct but it's as if the cursor
were transparent. I suspect that's the case and the cursor image
is being picked up from somewhere else in memory.
03-Sep-97 cmd/aux/vga
=====================
The following change allows the ViRGE/VX cards to work at 640x480x8 and
800x600x8. Unfortunately the hardware cursor refuses to work at 640x480x8,
no idea why.

At which resolution did you test it?

>>> Diamond Stealth 3D 3400.
>>At which resolution did you test it?
640x480x1
1024x768x8
1152x900x8 (the one i'm using now)
1280x1024x8
one of the 640x480 modes did give odd results, come
to think of it; i think it was 640x480x8. i don't know that i've
got the vgadb entries for much more than 1280x1024,
and that's compact enough on a 17" monitor.
i might try 1600x1400x8 tomorrow.
i use this vgadb entry with monitor=multisync135 (it's a Viewsonic PT775, and
quite nice too).
ctlr
0xC0043="Stealth 3D 3000" # Diamond Stealth 3D 3000/3400
link=vga
hwgc=s3hwgc
ctlr=virge link=ibm8514 linear=1
you must have a version of /sys/src/9/pc/vgas3.c that does
the right thing to find the hardware cursor storage in linear mode but
i think that's part of another boddle. if you haven't got that (yet),
remove linear=1.
other lines that are used for 1152x900x8 are
include = 1152x900@70Hz # 72Hz, 67.9KHz
clock=100
shb=1184 ehb=1376 ht=1472
vrs=900 vre=902 vt=940
#hsync=- vsync=-
...
multisync135 = 1152x900x8
include=1152x900@70Hz
multisync135
alias=multisync75

jmk's aux/vga changes worked fine on Plan 9 with my new
Diamond Stealth 3D 3400.
