Official BIOS release for the ASRock 770DE3L, an AMD 770 chipset desktop motherboard, packed in a small ZIP of about 660 KB. A vendor update file like this is normally flashed through the board's own update utility. To recover a board with corrupt firmware, the binary can also be written to the flash chip with an external programmer. Some vendor images carry headers or a different size than the chip expects, so check the file before programming and save the original chip contents first.
