BIOS archive for a Lenovo machine labelled S2 2017, using Quanta board DA0PS9MB8E0 at revision E. The 7.32 MB RAR does not state its tested status, so treat it as a reference image and verify after flashing. Quanta numbers its laptop boards with the DA0 prefix followed by a project code, here PS9. Technicians typically program such an image into the SPI chip with an external programmer to fix a no-boot or corrupted firmware fault. Dump and save the original chip first and confirm the flash capacity matches the file.
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.
