BIOS firmware for the ASRock A75 Pro4 motherboard, an AMD A75 chipset desktop board, compressed as a RAR of about 2.81 MB. No version number or revision is given in the name, so check contents before use. Such files are used either for normal updating or for programming the SPI chip directly with an external programmer after a failed flash. Compare the board revision on the PCB, read and keep the original chip image, and confirm the file size equals the chip capacity, since an oversized image will not fit.
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.
