BIOS firmware archive for the EMAXX EMX-ANF82HD-PRO desktop motherboard, version 1.6 according to the name. The RAR holds a 1.10 MB package that should contain the flash image for the board's SPI BIOS chip. Technicians use such a dump to recover a board that fails to post after a corrupted update, writing it with a programmer such as a CH341A. Read and save the original chip contents first, and confirm that the image size matches the capacity of the installed flash chip before writing.
