Working BIOS dump for the Acer 4745, Quanta board number written in the name as DAOZQ1MB8F0, packed in a RAR archive. The letter O probably stands in for the zero of the usual DA0 Quanta prefix, so read the actual PCB marking to confirm. The file is intended for restoring a corrupt SPI BIOS chip with an external programmer. No revision is stated, so compare carefully with your board. Back up the original chip first and verify the image size matches its capacity.
