i had problems installing the avga card,
my MB has onboard gfx, ati unfortunately, but it was no hassle to use the ati driver removal utility listed on the ultimarc site in the instructions of the avga card.
it took 3 or 4 tries before i got it to load the drivers fully, then i found a problem that when ever i tried changing resolutions...or colour depth or anything really, my monitor would shut off complaining of 'input not supported'
i was using an analouge tft monitor, plugged into the dvi output of the card with an adaptor (which is how your supposed to do it)
i eventually found that this was an issue, and there is a driver specificaly for that problem... but it's for when your using an analouge lcd monitor only, no digital one and no arcade monitor connected,
that wasnt what i wanted, i was using the lcd monitor to set the system up on my desk, before i put it in the cab, but also when it's in the cab, the arcade monitor vga out will be feeding the arcade monitor, and the dvi out will be feeding the active marquee screen, which may well be an analouge monitor as i'm getting the cheapest 24 inch widescreen monitor i can find.
anyway, i tried the other driver offered on the 'hidden' drivers download page on the ultimarc site, and all was well,
tho i havent tried it on the arcade monitor yet,
for those wondering,
http://www.ultimarc.com/avgadrivers.html is the drivers page on the ultimarc site.
i have notices the CCC dosent work, i'm running sp3, so i guess that's why, but i think i can live without it, as i'm not using rotation or owt.
