Pegatron H36FD firmware, board revision 2.1, UMA version, packed as a 1.78 MB 7z archive. UMA means the board relies on integrated graphics without a discrete GPU, so the image should not go onto a board fitted with dedicated graphics. Pegatron is an ODM that builds boards for several laptop brands, so the model is best confirmed from the PCB marking. Open with 7-Zip, check the extracted image size against the flash chip, and keep a dump of the existing chip before programming.
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 @biosfiles. Enginerys does not host this file.
