BIOS dump for a Casper laptop, model HU133U at board revision 2.0, labelled as working and 100 percent tested, and packed in a 6.99 MB RAR. It is meant for reprogramming the SPI flash with an external programmer when the machine has corrupted firmware, will not power on or shows no display. Before writing, back up the existing chip, check that the board revision matches 2.0, and confirm that the image size equals the chip capacity, because a mismatched file will not fit.
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 →
