BIOS image for board NB2766_PCB_MB_V4, also labelled A18S, at revision D and marked as fully working. The 7.16 MB RAR does not name the laptop brand, so identification relies on the board markings, which must match including the revision letter. Technicians use such a dump to restore firmware on a corrupted SPI chip with an external programmer. Back up the current chip before erasing, compare file and chip sizes, and expect that serial or system data may need re-entering after flashing.

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 →
