BIOS image for the ASRock H77 Pro4 MVP desktop motherboard, built on the Intel H77 chipset, with the name stating an 8 MB flash size. It comes in an 8.52 MB RAR archive. Such a dump is written to the SPI flash chip with a programmer like the CH341A when a board is bricked by a failed update or corrupted firmware. Read and save the original chip contents before flashing, and confirm the chip is 8 MB, since an image whose size does not match the flash device will not fit or verify correctly.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
