Anyone have a clue on how to reinstall XP pro over XP pro SP2? Doing it conventionally, gives me an error that the version I'm trying to install is older than the one on the disk. It seems that there should be a "just do it dammit" option somewhere. Constraints: The machine has no CDrom other than USB, and no floppy. (Toshiba Libretto L1) -- Feel the power of the dark side!
