Hi! I came about this problem some time ago - on a physical migration, P4->AMD64x2, but the hints I got was from virtual pc http://tecbites.blogspot.com/2008/02/migrating-windows-xp-from-pentium4-to.html http://blogs.msdn.com/virtual_pc_guy/archive/2005/10/24/484461.aspx http://support.microsoft.com/kb/953356/en-us (this is about sysprep, but the same situation)- Officially, of course, it is not supported by MS to migrate between intel and amd processors - or, between a current one an such an old one as a PIII ;) Don't ask me why a repair install does not automatically disable the processor and intelppm drivers ... it doesn't. Instead, they write about it that it doesn't work ...
