Well, many BIOSes trigger an SMI# when doing inb/outb to the keyboard ports so they can emulate a PS/2 keyboard when a USB keyboard is inserted. Do you have any BIOS options related to the USB legacy compat? I know of the Nehalem systems I've seen they have a separate option for controlling port 60/64 emulation which we leave disabled by default. -- John Baldwin
