Abstract
A computer system as provided with an internal flash ROM which includes the BIOS. In the event the flash ROM becomes corrupt, a special purpose interface allows for mode switching of a standard parallel port from a standard peripheral interface, such as a printer interface to a special purpose interface to enable the BIOS to be executed from an external ROM or another computer connected to the parallel port.
