Keyboard error on boot for 2 different systems (same chipset)

[Xuttah]

I have 2 systems. One is using an Asus A7N8X Deluxe, the other is an MSI K7N2. Each time either system boots, I get a "No keyboard found or keyboard error. Press F1 to continue." Funny that I can still press F1 and continue to boot normally.

Can anyone offer a suggestion? I probably just need the latest bios, but it started happening without warning. FYI, I have a wireless keyboard (using PS2 port) on one system, and a normal PS2 keyboard on the other.

Thanks,
