Skip the floppy, and buy a flash card reader that fits into the 5 1/4" slot instead, and make sure it's able to read the various types af flashcard. Throw in a USB flashcard keyring and you/they'll never look back.

I'm a big supporter of skipping floppies too, however have you ever tried to load XP onto a SATA raid? Funny thing about that, XP has NO options to load 3rd party drivers from anything other then floppy. So your thinking just get a USB floppy, and maybe theres a way around it but even after disabling floppy in bios it still comes up as b: not a: which has to be used by XP.... theres no way around it and it's my biggest peeve with microsoft right now...
