BIOS dump for the Acer eMachines G620, built on the Quanta ZY5 platform with board number DAZY5DMB6CO. The image is a raw 1.00 MB binary intended to be written directly to the SPI flash chip with a hardware programmer such as a CH341A. The DA-prefixed numbering identifies Quanta as the board maker, so the same number silkscreened on the PCB should be confirmed first. Read and save the original chip contents before erasing, and check that the chip capacity matches the 1 MB image before programming.
