BIOS and EC firmware set for the Lenovo ThinkPad 13 built on Quanta board DA0PS9MB8E0, revision E, supplied as a 5.24 MB RAR archive. Having both the main BIOS and the embedded controller firmware helps when a board fails to power on or charge because of corrupted EC code. The DA0 prefix marks Quanta's numbering, so the ODM is Quanta even though the machine carries the Lenovo brand. Back up each chip before writing, confirm the revision on the PCB is E, and check every image size against its target flash chip.
