BIOS image for the Gigabyte GA-770T-USB3 desktop motherboard, revision 1.0, packed in a RAR archive of about 2.14 MB. The name indicates a 1MB firmware dump, matching the capacity of the board's SPI flash chip. Technicians use such a file to recover a board that fails to POST after a corrupted update by writing it with an external programmer such as a CH341A. Confirm the revision printed on the PCB matches, read and save the original chip contents first, and check the image size equals the chip capacity before writing.
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.

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 →
