BIOS image for an Acer laptop on Quanta board DAZAARMB6E0, revision E, taken from a W25Q64 flash chip, in a RAR archive of 10 MB. The W25Q64 is a Winbond 64 Mbit (8 MB) SPI device, so the extracted image should be exactly 8 MB to fit. Quanta DA-numbers carry the board revision in the trailing characters. Technicians write this with a CH341A or similar programmer to repair no-boot or no-display faults caused by corrupted firmware. Save the original chip first and confirm the revision E marking on the PCB.
