BIOS for the ASRock H87 Pro4 desktop motherboard, revision 1.04, delivered as a 5.02 MB RAR archive. This Intel H87 board keeps firmware on an SPI flash chip that can be reprogrammed with an external programmer when the board fails to post or an update has gone wrong. Check that the extracted image matches the chip capacity, as vendor update files sometimes differ from raw dumps. Read and save the current chip contents first so the original MAC address and settings can be restored if needed.
