Firmware dump tagged P.DG A4010G A-000-1A1-A4 with a stated 4MB size, packed as a 3.38 MB RAR. No brand, model or board number appears in the name, so the target device has to be identified from markings on the board before it is used. The 4MB note implies a 32 Mbit SPI flash. Back up the original chip with a programmer before writing anything, and check that the extracted image is exactly the chip capacity, because a file of the wrong size 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.
