Working BIOS dump packed in a RAR archive, labelled for a board marked WN2A_DB revision V10 with a date stamp of 2019-08-14. The name does not state the laptop brand or model, so identify the target by matching the WN2A_DB marking and V10 revision silkscreened on the PCB. Extract the image and write it to the SPI flash with a programmer such as a CH341A, after first reading and saving the original chip contents. Confirm the image size matches the flash capacity before writing, since a mismatched file will not fit.
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.
