BIOS image set for the Acer Aspire 5755 using the Compal LA-6901P motherboard, with the P5WE0 project code given in the name. The 1.80 MB RAR archive is meant for reflashing the SPI chip with a programmer when the laptop shows no image or fails after a bad update. LA-xxxxP numbers identify Compal designs. Compare the board label against the name, and dump the original chip before erasing it. An image that does not match the flash size will not program correctly.
