BIOS and keyboard EC firmware pack for the Acer Nitro AN515-54, platform EH5VF, built on the Compal LA-H501P motherboard. The 5.85 MB RAR should contain the main SPI BIOS image plus the separate KBEC (keyboard/embedded controller) firmware. Compal uses the LA-xxxxP pattern for its board numbers, so verify that code on the PCB silkscreen. Typical use is reflashing a dead or looping board with a CH341A-type programmer. Always dump and keep the original chip before writing anything.
