I just purchased a new ASUS A7A266 motherboard with a 1.2GHz processor. I installed it and all the components in my existing case, with a 250w power supply.
I can enter the BIOS setup using the DEL key, but once there, the keyboard does not respond, although it did at first. I have tried two different keyboards, a Microsoft natural and a generic 102 key model, both known to work on my other bench system. The keyboard connector does not seem to fit snugly so I am leaning towards a defective motherboard socket – but is there a way I can verify this?
I also found it interesting that the DEL key consistently works but I lose functionality in the BIOS, wnd the Windows 2000 boot menu, nor any other OS (Windows 98, DOS) outside of the BIOS even acknowledges my input.
