So if I buy a USB keyboard, will it work when I need to enter the BIOS, or do I need to have a PS2 keyboard?

There should be a "legacy usb" item in the BIOS - enable that and usb mice and keyboards should work.

Just to expand on this a little, a recent BIOS might simply accept USB devices. If the Legacy USB referred to by SavageKarma exists in the BIOS options, then if it isn't already set it will need to be enabled using a PS/2 (or serial) keyboard prior to using the USB.

That will also mean if the BIOS settings go back to default (eg if the backup battery goes flat), an older type keyboard will probably be needed again to re-enable Legacy USB.
