Gigabyte's dual BIOS technique is simple, and the backup BIOS does not detect the BIOS in the case that the main BIOS can boot. Overwrite the main BIOS (note, overwrite, not boot from backup BIOS) from the backup BIOS only if the main BIOS fails (this failure is typically a software failure).
Method 1: Short-connect Mainbios
Note that the short line is not red, but the blue line.
The specific method is: in the case of power off, according to the Blue line shown in the figure to connect the Mainbios two feet (the actual is short 1, 8 feet), this trick is very useful and then press the chassis power on, the motherboard after a few seconds after power off automatically restart the power, At this point can be disconnected just short mainbios two feet (this step is critical), then the motherboard can be a smooth self-test boot.
You can now press end directly to enter Qflash to refresh the BIOS, or reboot again, the BIOS will prompt Mainbios checksum error and automatically restore from Backupbios.
Method 2: Press the reset key to boot
This is also the time to pay attention to releasing the Reset key. The specific method is: Disconnect the motherboard IDE and SATA data cable, unplug the motherboard battery, empty the CMOS, in the case of power off, press and hold the Reset key, press the power button to boot, the motherboard power after a few seconds will automatically power off restart, then you can release the Reset key, When the motherboard is powered on automatically, it will prompt for Mainbios checksum error and automatically restore from Backupbios.
Method 3: Press and hold the Power key in the shutdown state for more than 30 seconds the system will automatically recover
