What about restrictions on hardware changes that WinXP Service Pack 2 imposes? I was able to boot WinXP original from startup or in VMWare until that SP2 thing crawled in; forums tell that SP2 tolerates as much as three hardware changes before stalling startup (BSOD, in fact), but VMWare implies much more than those: RAM type, brand and amount; ethernet "card", processor, disk(s), sound card, motherboard... And it simply doesn't run. »
