Firmware archive in RAR format, 1.46 MB, whose short name Xn0m gives no model, board number or chip details, so the device it belongs to cannot be identified from the name alone. Open the archive and inspect the contents before use: look for a readme, a BIOS or EC image and its exact size. Compare any image size with the capacity of the SPI flash on the board, since a mismatched dump will not fit. Always read and save the original chip contents with a programmer before writing anything, so the board can be restored if the file proves wrong.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
