BIOS dump archive for a Lenovo M92P desktop on the IQ77T board, revision 1.0, compressed as a 5.36 MB RAR. The name ties the image to that board and revision but gives no firmware version or tested status. Desktop technicians use such images to recover a board with a corrupted BIOS by reflashing the SPI chip with a programmer like a CH341A. Before writing, dump and save the original chip, verify the board revision on the PCB and make sure the image size matches the chip capacity.

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 →
