BIOS firmware for the Acer Aspire 5749 and 5349 laptops on Quanta board DA0ZRLMB6D0, packed in a 1.54 MB RAR. Quanta mainboards are identified by DA0 codes, where ZRL is the project and MB marks the motherboard. A dump like this is flashed to the SPI chip with an external programmer to revive boards with corrupted firmware. Check that the DA0 code on the PCB matches exactly, back up the original chip before writing, and ensure the image size fits the installed flash chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
