  • Information processing system, information processing device, BIOS updating method for information processing device, and BIOS updating program for information processing device
    Patent number: 11314665
    Abstract: An information processing device includes: a BIOS flash ROM that is connected to a shared memory having an alternative BIOS written therein and being accessible using a MMIO, and that stores a currently used BIOS; a processor that can execute the currently used BIOS immediately after resetting; and a retaining means for retaining a setting indicating whether updating of the currently used BIOS is possible. The BIOS includes: a procedure for executing determination as to whether updating is possible after initialization necessary for executing the determination; a procedure for executing initialization necessary for updating the currently used BIOS to the alternative BIOS read from the shared memory, if updating is possible; a procedure for executing updating if updating is possible; a procedure for executing initialization necessary for operating the information processing device if updating is impossible; and a procedure for calling a boot loader if updating is impossible.
