Firmware package for the ASUS P8Q67-M D0 motherboard, a 5.43 MB RAR archive; the BR suffix is not explained in the name and should not be assumed to mean a specific region or version. Inside you should expect a BIOS image intended for programming the board's SPI flash chip. It is useful when the board no longer posts because of damaged firmware. Before writing with an external programmer, dump and keep the existing chip contents, check that the file size equals the chip capacity and confirm the board model printed on the PCB.
