BIOS for the Casper C600 notebook built on Quanta board DA0LG9MB6E0, here labelled revision 3, in a 4.7 MB ZIP. The DA0 prefix identifies Quanta numbering, and Quanta manufactures this board for Casper. The image is intended for writing to the SPI flash chip with an external programmer. Because another dump for the same board carries a different revision marking, compare the revision on your PCB carefully, save the original chip contents, and make sure the image size matches the 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 @biosfiles. Enginerys does not host this file.
