can't install drivers

I installed windows 2000 advanced server on my system

pIII 800Mhz
mb: P6S5AT

the motherboard cd does not auto detect anything
a cannot manually install drivers using the cd
i downloaded new drivers for that motherboard and could not manually install them
i even update the bios

i double checked branding on the motherboard and it is a p6s5at.

windows 2000 server is listed as a support os.

how do i install drivers????

 

yup, does not auto detect anything


1 more note, i have 2 other xp OS's installed on different partitions and they work fine with the p6s5at drivers. it must be something with win2000
