There are several alternatives for this:
- The Q-Flash Utility (embedded in the BIOS),
- The @BIOS Windows utility
- The FLASHSPI.EXE MS-DOS utility (included with the BIOS update)
As I don't use DOS or Windows, I always use the Q-Flash Utility.
Once I unpacked the BIOS, I copy it over to a USB stick (USB flash drive or DiskOnKey).
Reboot, and enter Q-Flash (hitting the End key in the welcome screen, or F8 in the BIOS)
The Q-Flash main screen appears:
Now we insert the USB stick, and select "Update BIOS from Drive"
Edit: Based on comments from some readers, it seems not all USB sticks are recognized at this point. So, if yours is not, you might need to reboot with the USB stick plugged-in.
Selecting it allows me to navigate down to where I put the BIOS in the USB stick.
That's it, after a confirmation message, the BIOS is updated, and my PC reboots.
NOTE: It's very important, and many users forget to do that, to reset your BIOS settings to the "Optimized Defaults".
This guarantees that there are no left-overs in the configuration from a previous BIOS version.
Now, we can move on to Configuring the BIOS Settings
