Method and apparatus for updating a program

摘要

BIOS updating is performed after saving an old BIOS to a spare storage area (91b). A current version BIOS stored in a first bank of a flash ROM (52) is moved to a second bank of the flash ROM, and a new BIOS supplied from a home server to a network interface card is stored in the first bank to complete BIOS updating. If the new BIOS does not run well, the old BIOS in the second bank of the flash ROM is moved to the first bank through a RAM to be reinstalled.
