Dell BIOS dump labelled UC5 with an ME++ tag, associated with Compal board LA-G891P. The ME++ marker usually indicates an image whose Management Engine region has been reset or prepared for reuse on another unit, though the archive content should be verified. Compal uses the LA-xxxxP numbering for its laptop boards. Before programming the SPI flash, dump and keep the original chip, compare the image size with the chip capacity and confirm the board number on the PCB matches.
