BIOS dump for a Dell Precision M4800 on Compal board LA-9772P, with the Management Engine region cleared, giving a clean ME so the Intel engine initialises fresh after flashing. The 4 MB size suggests a full image for one SPI chip. Compal's LA-xxxxP pattern identifies the board maker. Technicians program it with a CH341A or similar to fix boot problems tied to a damaged ME. Read and keep the original chip first, since it holds the service tag, and verify the chip capacity matches.
