Abstract
A computer system includes a flash memory device for storing BIOS code. The BIOS code is stored in an unprotected area of the flash memory. A boot block, stored in a protected area of the flash memory, is used for rebooting the computer system in the event that the flash memory device becomes corrupted. During normal operation, the BIOS code is updated using a radio link. If the BIOS is corrupted while being updated, a recovery routine stored in the boot block is executed. The recovery routine permits the corrupted BIOS to be reprogrammed using a serial interface instead of the radio link.
