Combined BIOS and EC firmware archive for the Compal board LA-E811P, revision 2.0, used in the CSL50 and CSL52 projects, reported as working. Compal uses the LA-xxxxP numbering, with the four-letter codes naming the platform. The EC image controls power-on, charging and keyboard functions, so a bad EC can leave a board dead even with good BIOS. Extract the archive, identify which image goes to which chip, check sizes against chip capacity, back up the originals and confirm the revision.

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 →
