Asus p4s800 Thanks and sorry for I'm late, HDD died. Biosmod doesn't work. Flashed from DOS, BIOS works, but no SLIC info in BIOS therefore can't activate. Btw, seems useless to install Vista/7 on this MB. SiS648FX has AGP but there is no AGP drivers (built in Win or provided by manufacturer) for Vista/7. Drivers from XP doesn't work.
