BIOS or firmware dump packed in a 954 KB RAR archive and identified only by the code CP2 08219-148.4K801-011. No brand or model appears in the name, so the target device has to be confirmed by the part number on the board or chip. Such dumps are written to an SPI flash chip with a hardware programmer to restore a corrupted BIOS. Read and save the original chip contents first, and check that the image size matches the chip capacity, because a mismatched image will not fit or boot.
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.

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 →
