Download onto a floppy, a bootdisk from bootdisk.com , and use it to fdisk and
format the system. This way you can put whatever you want on it. Do this *only*
if don't have an entry of XPee in the 'add/remove' list. If you see XPee there,
then you can uninstall it from there, and should be back to whatever OS you
had/used before you got screwed with XPee.
If you do not like it - even after switching to classic view, then the
only way to remove an operating system is to format the disk as part of
installing a different one.
