I think it's worth mentioning that if you're using an USB keyboard, you may not be able to get into your BIOS. I have a friend whose computer now has two keyboards; one PS2 for getting into his BIOS and the other USB for everything else. Oddly enough, once he's accessed his BIOS with the PS2 keyboard, he can use the USB keyboard to make BIOS changes. I don't know who came up with this design but it really does defy logic.
