BIOS dump for the Acer Aspire R7-572 on Compal board LA-A021P, with V5MM2 being the Compal project code shown in the name. Compal uses the LA-xxxxP pattern for boards it builds for Acer and other brands. Such a file is used to reprogram a corrupted SPI flash when the notebook fails to post or loops on power. Confirm the LA number on your PCB, back up the original chip with a programmer, and verify that the image size equals the flash capacity before writing.
