I have a home built PC with megatrend Motherboard using Abit i added dual core intel pentium so can i run 64 bit versions on it, also i have tried in vain to find out what clone the motherboard is, so does it matter what version key i use, as i have had enough of paying out hundreds on xp flavours from 98SE to XP home and professional. While i am asking, i tried to locate windows xp pid checker but most places have removed it for one reason or another, yet there is one for 7 which i am using now and the Dell key along with slui is working fine.
Use any XP x64 key, preferable one by M$ from the stickies (ofcourse with slp string & oembios set for your box) sebus
