Firmware archive tagged with board number LA-E791P and marked OK, which suggests a working dump, catalogued under the Apple brand. The LA-xxxxP pattern is Compal's motherboard numbering, so verify carefully that the board in hand really carries this number, since the brand tag and the Compal scheme are an unusual pairing. The 5.24 MB RAR should be unpacked and checked for the actual image before use. Read and save the original chip contents first, and confirm the image size fits the flash chip before programming it.
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 @BiosSchematicWorld. Enginerys does not host this file.
