Hey all, I tried this board with Win2000 and Win98se.
Neither o/s would recognize bios irq assignments.
Also, with USB 1 & 2 disingaged from the Bios, both 98 and 2000 insisted on loading the USB drivers...
Plug and Play was set to "no," and 2000 was installed as "Standard PC."
Verdict: the board was returned and an Asus P4PE purchased, which works flawlessly except for LAN difficulties (need it to update the o/s).
