I have the M9034LL/A Apple Keyboard, USB from there site at http://store.apple.com/1-800-MY-APPLE/WebO...plm=M9034LL%2FA
works great in OSX. Haven't tested in WindowsXP yet but my main problem is that I do dual boot with WindowsXP and OSX and it will not let me type or anything at the Dawin Boot prompt so I cant select anything on that prompt. Anyone have any ideas? or should I just send this back and get another keyboard?

Try playing around with the USB keyboard options in your BIOS I actually have to change those everytime i switch from OSX to windows XP
