Re:Check your BIOS (Score 1)

thats what the keyboard setting is for in the bios. (At least in my box which uses AMI Bios) There is a setting which allows you to tell the MB that its ok to boot normally if there is not keyboard. I think you can do this in AWARD. If I'm not mistaken there is a setting on which you set either IGNORE or HALT if a "Serious" error occurs. Play around, you'll find it if your BIOS is fairly recent.
