See my sig.
The first time I tried to install the chipset drivers on the Abit NF7-S, I had to do it one-by-one. Since then, I found my board undervolts vcore (check with mbm5 etc). Since upping the voltage to provide the chip with standard, everytime I've reinstalled the chipset drivers it went w/o a hitch. That is, at first the install proggie for the drivers w/n work and thus had to go one at a time. Now the installer works fine and I'm very stable.
Oh, there's a patch for sound for 98se you may need.
