RAR archive of 5.72 MB carrying a BIOS or firmware file under a generic name with no device, brand or board information. The contents must be identified before use; extracting it and checking image size and embedded strings in a hex editor or UEFI tool is a sensible first step. Firmware dumps are normally written to an SPI flash chip with a programmer. Always read and store the original chip contents, match the board number on the PCB, and make sure the image size equals the chip capacity.
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 @skclappybios. Enginerys does not host this file.
How to open a .rar file
Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
