Unlocked BIOS dump for an HP x360 2-in-1 convertible built on the Compal LA-L321P motherboard, packaged as a 7.66 MB RAR. The unlock label usually means the image has a password or similar lock removed, though the name does not say which. Compal identifies boards with LA-codes followed by a letter suffix, and that code is printed on the PCB. Before programming the SPI flash with a clip and programmer, read and save the existing chip, confirm the board code, and check the dump size matches the chip capacity.
