BIOS firmware for the Acer A515-51G laptop on Compal board LA-E892P revision 1A, in a 4.87 MB RAR archive. The G suffix marks the model variant with discrete graphics. The Compal LA-xxxxP code and revision are silkscreened on the board and should match before flashing. Write the image to the SPI chip with a programmer such as a CH341A-class tool or similar to recover a bricked board. Back up the existing contents first, and verify that the image size fits the flash chip.
