Firmware dump for the HP 440 G2 laptop on a Compal LA-B181P board, labelled M73 and described as a full DMI image, so system identification data should be present. The ZIP is about 4.71 MB. LA-xxxxP is the Compal numbering style, and the board code on the PCB must match. Back up the existing SPI chip with a programmer before writing, and compare the image size to the chip capacity. Because DMI data from another unit is included, serial and model fields may need editing afterwards.
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.
