BIOS firmware for the Biostar X470GT8 motherboard, board version 5.x, in a 19 MB RAR archive. The X470 name points to the AMD X470 chipset for Ryzen desktop processors. Such a dump is used to recover a board after a failed update by writing the SPI flash directly with an external programmer. Confirm that the board version printed on the PCB is 5.x. Save a backup of the current chip contents, and check that the extracted image length matches the flash capacity before programming.
