G45M03 REV A00 U21 1MB

BIOS .rar 1002 KB Shared

Firmware dump for a G45M03 motherboard, revision A00, taken from the chip at location U21 with a stated capacity of 1 MB. The archive is about 1002 KB, consistent with a single 1 MB image. The U21 reference helps locate the flash device on the PCB before desoldering or clipping onto it. Program it with a standard SPI programmer after verifying the chip ID and capacity match, and read out and keep the existing contents first in case the replacement image does not boot.
