BIOS dump for the Lenovo ThinkPad E40 on board DAGC5BMB8C0, revision C, packed as a 653 KB 7z archive. The name also notes the 8L board marking and a Winbond W25Q16V flash chip, a 16 Mbit (2 MB) SPI part. DA-prefixed numbers like this follow the Quanta ODM scheme. Such a dump is written with an SPI programmer to revive a board with corrupted firmware. Read and keep the original chip contents first, since they hold serial and system data, and confirm the PCB number and revision match.
