I've only readed first post:
Very good you already have a script
You are great. I've tested your script in 64XP build from Lancelot. So beautiful that I'll give you
Great work. 64LiveXP works flawlessly in qemu.
My cpu = P4 3.0, qemu is no problem with 64XP but with 7 or vista or 2k8, it cant boot.
No time to look in dept of scripts, generally it's GREAT!
