I've just replaced my old media keyboard with a standard Microsoft wired 600 USB one. It works fine once Windows (XP home edition) is fired up, but not while the computer is booting up. I've tried advice given elsewhere to uninstall the driver and get it reloaded while starting up; the new driver duly arrived, but it hasn't solved the problem. Do I need to do something to the BIOS, and if so _a_ what, and _b_ given that hitting a function button during the boot sequence how do I get at BIOS? Or what else do I do?
