BIOS archive for Acer Aspire 4745 and 4820T laptops on the Quanta DA0ZQ1MB8D0 board, revision D. Quanta uses the DA0xxxMBxx0 numbering, with ZQ1 naming the project. The 3.41 MB RAR should contain a flash image for writing with an SPI programmer to recover a board that powers on without display or after a bad update. Check that the PCB marking and revision D match, read and keep the original chip contents, and make sure the image size equals the capacity of the installed flash chip.
