BIOS archive for the Gigabyte GA-B250M-DS3H desktop motherboard, revision 1.0, size 5.23 MB. It can be used to reprogram the SPI flash chip with an external programmer when the board will not post or a failed update has corrupted the firmware. Gigabyte prints the revision near the PCIe slots or board edge, so confirm it reads 1.0. Back up the existing chip, which holds the MAC address and serial data, and check that the image size matches the flash capacity before writing.
