BIOS and embedded controller firmware for the HP ProBook 455 G9 on Quanta board DA0X9SMB8D0 revision D, in a RAR archive of about 25 MB. Quanta uses this DA-prefixed board numbering. Program the system BIOS into the SPI flash and the EC image into its own chip or region, using a hardware programmer. Read and archive the original contents of every chip first. Confirm the board number and revision D on the PCB, and check each chip capacity against its file before writing.

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 →
