Acer 4535G BIOS dump for Compal board LA-4921P, a 1.00 MB raw binary suited to an 8 Mbit SPI flash. The LA-xxxxP format is Compal's motherboard numbering, showing who manufactured the board. Check the number and revision printed on the PCB before use. Write the image with a CH341A or similar programmer to revive a board with corrupted firmware. Save the original chip contents first, then read the chip back to confirm a correct write.
