Dell Vostro A860 BIOS image for Quanta board DA0VM9MB6B0 at revision D, compressed into a 554 KB rar file. The DA0 prefix identifies Quanta as the ODM that designed the motherboard for Dell. Such a dump is used to revive a board with corrupted firmware by writing the SPI flash directly with a hardware programmer. Check that the silkscreen reads 6B0 and rev D, as the related 6A0 board differs, read the original chip as a backup and confirm the file size matches the flash capacity.
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.
