BIOS image for the ASRock A55M-HVS desktop motherboard, an AMD A55 chipset board, labelled as working. Delivered as a 5.19 MB RAR archive. When a board will not post after a failed update, the image can be written straight to the SPI flash chip with a programmer such as a CH341A. Save a backup of the current chip contents, check that the extracted image size matches the chip capacity, and confirm the model name on the board before flashing it.
