Firmware dump for the Acer ES1-431 family notebook fitted with the Intel Celeron N3150 processor, on board DAZ8ADMB6D0, project code Z8AD. The DA-prefixed number belongs to the Quanta numbering scheme, marking Quanta as the board maker. Inside the 3.35 MB RAR there should be a binary meant for the SPI flash memory, used to revive a unit that powers on without display or loops at startup. Confirm the PCB label reads DAZ8ADMB6D0, back up the original chip with your programmer, and verify the written data afterwards.
