So I've done all the normal steps, SP2 disc, install on boot camp partition, yada-yada. XP installs fine then boots but when it comes time to do XP's setup (the blue screen and set of dialogs establishing language and stuff after the install) after it says "installing devices" my keyboard and trackpad stop working and the mouse disappers making it so I can't continue through the dialogs and finish installing XP. What gives?
