Firmware for the Casper C810 notebook on board 08N1-18Y4Y00, revision 2.2, compressed into a 4.12 MB 7z archive. The name identifies the board number but not the ODM, so rely on the marking printed on the PCB to confirm compatibility. The dump is intended for programming the BIOS flash chip directly with an SPI programmer to recover a dead or bricked machine. Save a backup of the original chip before writing, and verify that the image size corresponds to 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 @biosfiles. Enginerys does not host this file.
