BIOS archive whose name only gives UH61AT EVO, apparently a desktop board model, with no brand, version or chip details stated. The 2.11 MB RAR presumably contains a flash image for recovering a board with corrupted firmware. Such dumps are normally written to the SPI chip with an external programmer when the system fails to POST. Since identification is limited, compare the board markings carefully, read and save the original chip first, and confirm the image size matches the flash capacity before writing.
