BIOS UPDATE UTILITY
The system BIOS resides on a flash ROM in the system. The flash ROM can be updated,
should it ever become necessary. This feature allows the ROM BIOS chip to be flashed with
a new BIOS code through software, rather than replacing the chip.
Performing an update is done with a flash update utility.
Use the following procedure to flash the BIOS with the utility.
