I just bought an OEM copy of XP Professional w/SP2 to install on a standard config mac pro. I partioned the drive on my 2nd internal HD. After Boot Camp Assistant reboots the computer...when the Windows installation reaches the point of "Press Enter to Continue Windows Installation" my Apple USB keyboard doesn't seem to work and I can't press Enter to get it to continue. I've tried plugging it in the different USB ports on the computer, but it still doesn't work. Anyone have any ideas on how to fix this? Thanks!!
