BIOS dump for a DNS laptop on the UW3 platform, board DA0UW3MB6D0 at revision D, with the name stating a 1 MB image. DA0...MB.. codes follow Quanta's numbering, so the ODM is Quanta rather than DNS. The 772 KB RAR should unpack to a binary sized for a 1 MB (8 Mbit) SPI flash, typical of EC or older BIOS chips on such boards. Write it with an external programmer such as a CH341A, but first read and save the original contents, and confirm the image size matches the chip capacity before flashing.
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.
