yet another vga bore

yet another vga bore

[rog]

unfortunately i do not have a manual for my video card,
as i've been putting a PC together on the (very) cheap.

unsurprisingly it doesn't want to work in anything other
than 640x480x[18] (when entered in vgadb as a vanilla mach32 card).

i was wondering if anyone had succeeded with a similar card.

controller is a mach32; clock generator type appears to be
ics2494am (is this the same as ics2494a ?), and i'm not
sure about the RAMDAC. (there's a TI chip labeled 'TLC34077 -110TN'
which is the only large chip besides the mach32, but i'm not
good at spotting RAMDACs by eye)

it's possible that it's a 'Graphics Wonder' (from checking
out the ATI home page), but i'm not sure.

the output from aux/vga looks like :
...

i guess it serves me right for buying second-hand hardware.

any help much appreciated.

  thanks,
