ZIP archive of BIOS or firmware labelled only fx706hma, about 7.1 MB. The name appears to be a model code but carries no brand, board number, revision or version, so verify everything before use. Open the archive and check whether it holds a raw SPI dump for a programmer or an executable update. A raw image is written with a CH341A or similar tool after reading and saving the original chip, and its size must match the flash capacity, otherwise it will not fit or will boot incorrectly.
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 @efibios. Enginerys does not host this file.
