BIOS firmware set labelled DA3UP, described as data for a mini PC with an AMD Ryzen 3 PRO processor, stored in a 5.16 MB RAR archive. Beyond the platform hint, the name gives no manufacturer, board revision or BIOS version, so verify the board marking and chip type before trusting it. Images like this are written to the SPI flash with a hardware programmer to recover a unit that no longer posts. Dump and keep the existing contents first and make sure the file size equals the flash chip capacity, or it will not fit.
