BIOS package for the Gigabyte B450 Gaming X desktop motherboard, revision 1.x, sized at 16 MB. The B450 chipset places it on AMD Socket AM4. The RAR should contain an image suited to the board's SPI flash, usable for recovery with an external programmer when the normal update method fails. Confirm the board revision on the PCB and the chip capacity before writing, and read the existing contents first, since the original holds the network MAC address and other board data.
