I've just flashed the BIOS for the second time, in this new build, and thought I needed to share what I've learned all in one place. I know I would've appreciated this collection myself, and probably will again next time around. For background, I'm running the GA-880GA-UD3H (v2.1) motherboard, but it seems these may be fairly generic instructions?
- Download the updated BIOS file directly from Gigabyte, and save it to your disk. It will (probably) be an EXE file.
- Execute the BIOS download, to extract its contents to a sensibly named folder on a FAT32 formatted USB flash drive. There will (probably) be several files, and the revised BIOS is in the one with an extension matching the revision number. eg, 88GAUD32.F7 for rev F7
- Reboot, and enter the BIOS setup by pressing the Del key during POST.
- With your digital camera, take a picture of every screen that's even remotely modified!
- Enter the Q-Flash utility (from within the BIOS setup) by pressing F8.
- Follow pretty dirt-standard prompts to update the BIOS from disk, and browse to the source file.
- Hold your breath, and pray you don't lose power for the next 30-60 seconds or so.
- Reboot when prompted, and re-enter the BIOS setup using the Del key during POST.
- Use the F9 key to confirm the new BIOS revision took effect.
- Choose the option to "Load Optimized Defaults", because everything has now been erased.
- Referring to your camera, reset all the BIOS settings to what they were. Don't panic when your RAID array(s) appear to have been wiped. After setting the controller(s) back to RAID mode, they will be recognized on the next boot.
- Save and reboot again. You may want to re-enter BIOS a time or two, to insure your settings all "took."
- Let the OS load and make sure things seem to be as they should be.
- If you have a USB keyboard, shutdown the system and hook-up a PS/2 keyboard. Seriously. The next step may very likely be impossible otherwise.
- Restart the system, and press Alt-F12 during the POST to initiate a prompt to copy the main BIOS over the backup BIOS. (This step appears to be undocumented, other than here in this forum!) Say yes, then wait until prompted to reboot again.
- Re-enter BIOS setup, and use F9 to confirm the main and backup BIOS revisions match.
- Press F11 to save a copy of your current BIOS settings from CMOS. Optionally, save a copy to HDD as well.
- Breathe again. You're done!
My thanks to
absic and
Dark Mantis for helping me through this the first time. Many of the hints above originated with them. It was my need to go searching for them again, and so soon no less, that prompted me to write all this up in a single post.
Question: Had I saved my CMOS to HDD (or flash) the first time around, would have have saved me from having to reset all the settings manually? If so, that'd be an important edit for this thread!
