Greetings I am considering converting an existing Alienware dual Opteron 250 Win/XP Pro system to Win-x64. I have 2 separate hard drives C: and D: with C: being the boot drive for Win/XP Pro. I would like to end up with a dual boot system with Win-x64 on drive D: . I tried to do my own research but havent had much luck other than finding this newsgroup. Do I need to update BIOS, disk drivers, CD/DVD drivers before I install ? Does anyone have any advice on what I should do before I convert ? Can someone point me to a link or other source of information that might help me do my own prep work ? Thanks for any help Barry C
