ThinkPad 13 DA0PS9MB8E0 Quanta OEM PS9

BIOS .rar 5.09 MB Shared

Firmware archive for the Lenovo ThinkPad 13, built by Quanta on board DA0PS9MB8E0 with the PS9 project code. Quanta boards carry DA0 numbers on the PCB, where the middle letters identify the project, so check this label before using the image. The 5.09 MB RAR is intended for reprogramming the SPI BIOS flash with an external programmer to recover a dead or bricked board. Back up the existing chip, since ThinkPad dumps hold machine-specific serial and UUID data, and confirm the image matches the flash size.
