Firmware for the Quanta U52 motherboard DA0U52MB6E0 at revision E, labelled U52-E, in a 2.14 MB rar. Quanta board codes follow the DA0xxxMBxxx pattern, with the project name in the middle characters. The image is meant for writing to the SPI flash with a programmer when the board has a corrupted BIOS. Save a copy of the original chip contents first. Check that the revision on the PCB is E and that the file size matches the 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.
