I think I have one of those. My Windows CD is referred to as a 'recovery
disk', and will only work on my machine (NEC). Once tried to do an
install with it onto another unbranded PC, but got an error message
saying that the machine was not recognised as a computer, or similar.

I've seen that with Compaq machines. What do you do if, eg you want to
extract the NTbackup tool while running normal XP, which isn't loaded
with an install? I thought you could not access this hidden partition if
at all without some specialised software, apparently. It will only
install just after POST (F10 key IIRC). Where is the special function
you mention located in CMOS?

Not quite. If it's a BIOS locked version, surely that means it wouldn't
install on another machine in the first instance, unless it included an
identical BIOS, or have I got that wrong?
