Tested BIOS image labelled LZ-801T V1.0, intended for a 16MB flash chip, packed in a 5.61 MB rar archive. The name does not give a brand, so LZ-801T is best treated as a board identifier to compare against the PCB silkscreen. Such dumps are written to the SPI chip with a programmer to recover a board with corrupted firmware. Confirm the board marking and V1.0 revision, save the original chip contents, and check that the chip really is 16MB.

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 →
