Hello everyone, I’m new to this great Win Raid forum.
Without further ado, I’ll tell you about my problem, although I’m sure it’s not a problem for you.
I have a Gigabyte motherboard, model ga-x79-up5-wifi rev 1.0.
I took the step of installing NVMe hard drives, and when it was installed, the BIOS did not recognise it so that I could install a new operating system. It is true that I can see it through my operating system (Win10) as a storage device, but I do not want it for that purpose.
The BIOS I have is f4, the latest update released for this motherboard.
My goal is to install two NVMe drives for the different operating systems I have.
I don’t know how to approach this. I would need a modified BIOS to use it for my purposes.
Can anyone help me with this process?
Thank you very much in advance.
Greetings to all and happy 2026!

Welcome to the Win-Raid Forum!
Please use the “Search” option of the Forum and enter “GA-X79S NVMe”.
Good luck!
Thank you, Fernando, for your welcome.
I have checked the forum, and the users who have posted queries have motherboard rev 1.1, which differs from mine.
How can I obtain a modified BIOS for my purposes?
Any help would be appreciated.
Best regards.
What about doing the required BIOS modification yourself? For users like you I have written an easy to understand step-by-step guide. >Here< is it.
If you are unsure whether you have done the BIOS modification correctly, please attach the original and your modded BIOS. Then someone among our experts will check it and give you a feedback.
Thank you again, Fernando, very kind of you.
Before I get into your recommendation, I’m going to tell you something that I haven’t mentioned out of prudence. First of all, I apologise.
Searching the internet for a solution to the above, I found a forum, which I no longer remember, for a f5g BIOS for the rev 1.1 motherboard.
I plucked up the courage to install it, and to my surprise, the BIOS recognised the NVMe drive. So far, so good, but over the course of a few days, I realised that the BIOS was doing strange things, such as restarting on its own, losing all the BIOS settings for a moment, until it restarted on its own and the settings returned.
Another problem was that the operating system would freeze.
Reading the link you sent me about manipulating the BIOS, I saw that you can’t have hard drives in RAID, which is how I have my operating systems set up.
I’m attaching the BIOS that I had working.
Is the PC unstable because of the RAID, or because it’s not for my motherboard revision?
Thank you.

@Trakerbam You can try this, but this one is based on F5f instead of F5g, also added Resizable Bar support: X79SUP5_NVMeRebar.rar (4.0 MB)
Hello, thank you very much Koekieezz.
I have tried this f5f version, but it works even worse than f5g. I have sporadic BIOS reboots, and the BIOS freezes.
wew, at what point it gave you reboots?
First of all, thank you very much for your help.
There are two ways in which the reboots occur.
The first is that, as I have four hard drives in RAID 0, with different operating systems plus the NVMe drive with Windows 11, when I select which drive to boot from and choose the NVMe drive, the BIOS reboots and sometimes crashes.
The second is that when I turn off the PC, I always disconnect it from the mains. When I plug it back in and turn on the PC (not always), the PC starts up and the BIOS reboots.
@Trakerbam Could you try this: X79SUP5_F5g Test.rar (3.9 MB) (this is based on Bios F5g you did share here)
I tried the test mode, and after reconfiguring the BIOS (safe mode boot, etc.), it froze, and I had to press the reset button to start it up.
After performing the manual reset, the operating system started up fine, but when I restarted it, it froze again like it did at the beginning.
Could the entire fault be due to the fact that this BIOS is for motherboard revision 1.1?
I am very grateful for all your help.
Without wishing to take advantage of your assistance, I am attaching the original BIOS for my motherboard, in case it is of any use.

I contacted Gigabyte eSupport and they gave me the F5h BIOS (dated 2026). NVME is still not supported natively, but you can try to add the NVME DXE driver to check whether the freezing issue is still there.
