Lenovo firmware package for Quanta motherboard DA0PS9MB8E0, revision E, described in the name as a working BIOS. The archive is 6.33 MB and does not name a specific laptop model, so match it by the board number printed on the PCB. Such dumps are used to recover a dead or locked board by programming the flash chip with a CH341A or similar tool. Read the original chip and keep that copy, then compare the image size with the chip capacity before writing. Revision differences can cause the board to fail to start.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
