I currently own an Asrock 4coredual-sata2. For the record, everything works perfectly with Win98 on it (with the exception of the audio chipset - no win9x drivers AFAIK). It works fine with 2 graphic cards. Right now, Win98 uses a GeForce 6200 AGP and XP/7 a 460 GTX (for those interested, this gives surprisingly good performance in recent games, assuming the screen and thus, the resolution is not too big). Here's my problem : I tried to replace the 460 GTX with a 760 GTX. Unfortunatly, It freezes on startup (I get no POST display). It seems the 7xx serie is not compatable with the 4coredual-sata2... which means that 6xx serie is probably not either since they are based on the same chip. I'm thinking about buying a (used) Asrock 4core1333-GLAN or 4core1600-GLAN. They have P31/G31 + ICH7 chipsets and a Realtek RTL8111B/RTL8111C LAN. Does anyone have an experience with Win98 on this card ? Will it support my 760 GTX and a 5200 PCI card for Win9x ?
