Rev 1.0 package for the Compal LA-E791P board used in the HP 15-bs526ur laptop, holding a BIOS dump and the matching EC firmware in a 5.42 MB RAR archive. Compal designs carrying LA- numbers often use separate firmware for different board revisions, and a sibling Rev 2.0 set exists, so the marking on the board must say Rev 1.0 before use. Typical uses are reviving a board after a failed update or fixing embedded controller faults. Save the original flash contents before writing with a programmer.
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 →
