Tested BIOS archive for the Dell Inspiron 1564 and 1464, Quanta board DA0UM3MB8E0 revision E, marked OK. Quanta uses the DA0 prefix scheme, so the code and revision on the PCB should match before flashing. The dump is used to recover a dead or looping board by writing the SPI chip with an external programmer. Extract the 1.70 MB RAR, save the original chip contents first, and make sure the image size fits the installed flash.
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 @generalbios. Enginerys does not host this file.
