Well, it keeps you from reusing the media on a machine
that it's licensed for, but what I'm trying to do is
setup my XP on my laptop in a QEMU session. I've looked
through the batch files, and it uses a partition quest
binary to do the actual restore, as long as it passes
the bios id check.

Yeah, I've already had another HP laptop disk crash.

Nope. Just the bios id.

Possibly. But it would be interesting to try to install
it *if* I could set the bios ID on the command line

well, again, I'm not terribly thrilled about Microsoft,
but I would like see if it's possible. If M$ did something
else to prevent it from running, then that I can't do
anything about. It is pretty fragile. When I tried to
remove the hibernate partition, XP stopped booting.

The bios id is part of the directory struture that HP

I suppose I could remaster the CD's to use QEMU/Bochs's
bios signature, but it'd be easier if I didn't have to

That may be worth pursuing, just so I can have a
recovery disk in case things really go boom

I have a copy of XPHome, but I would like to see if I can
get all the extras that are on the the rescue disks. I
can reinstall them from there, on to the XPHome, but
that's a lot extra work.
