[Request] NVMe Boot Support for GA-990FXA-UD3 R5

I really could use some help on modifying my bios to support Windows 10 boot capability off new NMVe drive. I have no experience at this. Thanks! Link to bios - GA-990FXA-UD3 R5 (rev. 1.0) Support | Motherboard - GIGABYTE U.S.A.

Follow the guide and you can share your mod file for further analysis, before flashing.

I gave it a go! I followed the guide and it looks like I was able to mod my bios. How do I upload or share for review? As a new user I get blocked for an upload. Thks!

I just got notified that I have more privileges!

modbiosf2.rar (2.8 MB)

Seems correctly done, no missing/added pad files in to the insertion volume.
You can use the standard 5 DXE, besides the small variant also does the job.
Use QFlash in bios, do not flash on OS environment.
Report back for future user guidance if you keep the shared file linked, good luck.

I did the QFlash and I now have a new drive in the boot list. I tried cloning to the NVMe drive from my current boot SSD Windows 10 drive but the the NVMe drive will not boot after cloning. Am I missing something?

Oh yes you are… the reading of the guide further more, setting the system as PURE UEFI environment and performing a new OS installation (Step 4), as cloning is never advised for NVMe system migration.

Cloning is keeping all OS previous junk and not achieving the best new NVMe performance migration of the new PCIe booting interface.

You are right! I stopped reading! It would probably be wiser to do a clean install to start off fresh and get rid of the junk. I’ll give it a shot and let you know the results! Thks.

Success! I gave it a shot and was able to get Windows 10 on my new NVMe drive. It’s taking a bunch of time to load on my applications that I use and get them set up the way I like. So thanks for the help and guiding hand and the guide itself!

I’ve got another issue that maybe someone could point me in the right direction to help solve. I have a Gigabyte GA-990FXA-UD3 Rev 5 motherboard and AMD processor. At startup, the computer often fails to start and does not enter the bios and then into Windows 10 like normal. It hangs with no beep. I sometimes have to start and power off the computer multiples times to get the computer going. Can anyone point me in the right direction to solve this? Thanks!

After the NVMe mod bios flashed (the one linked by you, above), not with the original bios i presume?

EDIT: And it was also like that, using old OS disk and no PCIe M.2 adapter/NVMe disk? What GPU you’re using or does it happen with other model/card and /or Legacy/UEFI…You know where i’m going with this right… the UEFI initialization is hardware component dependent, cpu, memory, and device initialization. this before next phase, the EFI System Partition and Boot Management, so…
In this point we are not pointing any issue with the used Small variant of the DXE/bios mod file used itself.

I have the same start up behavior with the new NVMe drive with the modified bios as well as before with the unmodified bios of the old SSD drive.

I suspect my graphics card might be the culprit, so I just bought another card off eBay to try out. It took 4 tries to get my computer to boot this morning. It’s making me nervous! I’m all backed up but afraid that one time it’s not going to start at all. The NVMe is working great!

It’s not the graphics card. Same result with a different card.

Motherboard issue maybe then…

I think you may be right. Time to upgrade pretty soon I think.
