> Hi, I'm having problems in an old PC with 2 S3 video devices. > (s3 Virge/DX and a s3 Trio 368) This is from rusty memory, those cards are way over 10 years old, but I'm recalling that there were HARDWARE design problems that prevented two of those cards from coexisting in the same system, there were VGA static resource mappings for memory and IO ports that couldn't be completely disabled. rather than waste hours on ancient junk that didn't work right when new, get some cheap generic ATI cards, even old ATI Rage cards will work way better than thoe S3 things ever did. There's a very good reason S3 is long out of business, they designed junk.
