Acer Aspire 4625G BIOS binary, marked with ZQ2 and 123, likely a platform code and a BIOS version number, though the name does not label them. The image is 1.00 MB, matching an 8 Mbit SPI flash. Technicians write it with a hardware programmer to recover from a corrupted or mismatched BIOS that leaves the laptop without picture. Check the motherboard platform code against the PCB markings, confirm the chip size, and dump the original chip contents before erasing so you can roll back if needed.
