Does this laptop have Firewire, but not a CD drive? If it has only a floppy, I doubt it can boot from FW. Because that object happens to be firewire, and not a whole lot of devices except macs boot from Firewire. Can't you just get a laptop drive and put in there? I can't figure out why you'd want an external drive over internal. Additionally, you can boot from the 4 floppies, then install Windows over the network.
