Firmware set for board IS7XM revision 1.0, with images labelled by the chip reference designators U4, U5 and U107. The name gives no brand or model. It is a 5.85 MB RAR archive. Locate each chip on the PCB by its U number, ideally with a boardview, and program it with the matching file using an SPI programmer. Before writing, dump every original chip, check that each image is the same size as its target chip, and confirm that the IS7XM revision printed on the board is 1.0.
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.
