A method for updating the contents of a BIOS ROM includes disconnecting a host system from the BIOS ROM, transferring data from a service processor to the BIOS ROM, and updating the contents of the BIOS ROM using the transferred data. A BIOS update system for a computer system, includes a BIOS ROM containing BIOS instructions, a service processor that contains update data for the contents of the BIOS ROM, an LPC bus that transfers the update data from the service processor to the BIOS ROM, and quick switches that disconnect a host system from the LPC bus.
