Tested HP BIOS dump for Quanta board DA0WJ7MB6E0 revision E, written for a 25Q32BV flash chip, which is a 32 Mbit (4 MB) SPI part. The file comes as a RAR archive of about 3.2 MB and is marked fully working. DA0 board numbers follow the Quanta naming convention. Program the image with a CH341A or similar programmer to recover a board with corrupted firmware. Back up the original chip first, verify that the PCB revision is E, and confirm the image is exactly 4 MB to match the chip.

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 →
