BIOS image for an A58M-A desktop motherboard, version 1401, in a 4.42 MB RAR archive; BR in the name likely marks a regional or source tag, though its meaning is not certain. The brand is not stated, but A58M-A matches the ASUS naming for this model. Images like this are flashed onto the SPI chip with a programmer to revive a board that fails to post after corruption. Confirm the exact model on the PCB, as close variants such as the USB3 version need different files, and keep a backup of the original chip.
