Firmware package for the HP 15-ba102ur laptop on Compal board CDL51, number LA-D712P. At 14.9 MB the RAR archive is larger than a single flash image, so it may contain several files, such as multiple dumps or tools; review the contents before use. Compal numbering in the LA-xxxxP form is printed on the PCB and identifies the exact design. Technicians use such files to restore a board with corrupted BIOS by programming the SPI chip externally. Match the board number, back up the original chip and confirm the image size equals 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 @biosarchive. Enginerys does not host this file.
