Abstract
A portable computer system wherein the printer port can be used, at the user's option, not only for connection to a printer, but also for connection to an external floppy disk drive. If the BIOS determines that there is an external floppy drive attached, the BIOS disables the normal operation of the parallel port in order to allow the external floppy to operate.
