BIOS image for the Gigabyte GA-945GCMX-S2 motherboard, labelled as confirmed working, in a 365 KB RAR archive. The name gives no board revision, so compare it with the revision printed on your PCB and with other images for this model before flashing. The dump is typically written with an SPI or LPC-capable programmer to revive a board that powers on without POST. Save the original chip contents first, and verify the file size matches the capacity of the installed flash chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
