RAR package of BIOS firmware for the Acer Aspire E1-572G built on Compal board V5WE2, numbered LA-9531P. The LA-xxxxP format is Compal numbering, Compal being the ODM that manufactured this mainboard for Acer. The 1.65 MB archive should be opened with WinRAR or 7-Zip and its image checked against the SPI chip size before use. Make sure the PCB label carries LA-9531P, read and store the original chip contents, and verify after programming with a hardware flasher.
