I changed the pid with no luck. Yes it is an upgrade XPHome edition but you can do a clean install by just showing it a 98, ME, 2000 cd. The install will complete by itself after I insert the win9x cd and then reinsert the unattend cd. It's not a real big deal to do that, but not as nice as just booting from 1 cd. I will check back if anyone has any other ideas.
