i can't speak for XP personally but i just
installed linux alongside w2k
 on my latitude C400 with no problems. I used ntfsresize to resize
 the partition.  No non-free software needed :)
 The ntfsresize page claims it works with XP.

thats great, thanks heaps...
i wish i didnt have to run Borg Edition at all... if i had my own way
it'd be software libre all the way on my machine, but for work its a
necessary evil...
will check it out, thanx heaps :)
