BIOS pack for Quanta board DA0R33MB6D0 revision D, project R33, in a 3.49 MB ZIP archive. The name says it holds a 1 MB and a 4 MB image, which usually means two flash chips on the board, so match each file to the chip it belongs to. The DA0 prefix followed by the project code is Quanta's numbering style, and Quanta is the ODM behind this board. Write the images with an SPI programmer after saving the original reads, and make sure each image size fits 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.
