I am trying to install XP Home SP3 via Boot Camp, and when Windows Setup begins my keyboard won't work. When Setup prompts me to press Enter to begin the install, nothing happens. I called Apple, and they did not know what to do other than remove and restore the partitions, unplug and re-plug the USB devices, and reset the PRAM. It's an OEM copy of Windows, so I can't call MS for help.
