@Snow Crash - Thanks, but it's @CompScientist that made this BIOS for you guys. If you want to donate it would be to him or you can donate to the site from the bottom of the page, thanks
Yes, PCIE 2.0 is limited more than PCIE 3.0, but it depends on what slot you are using (how many lanes your slot and PCIE adapter is giving the NVME to use).
That can be limited by the slot you put it into on the board, or the adapter itself may be limited to (x1, X3, X4 etc for example). Check lane width being used by the NVME with CrystalDiskInfo

I didn't see the rar on the first post :), it is a great win this bios for Gigabyte 990FXA-UD5 rev. 3.0, I flashed with the @BIOS flash software from official web page and now the M2 to PCIe adapter works well and I was able to boot from the M2 SSD - on Windows 10 Pro.
Thank you!

would it be possible to do with the GA-990FXA-UD5 (rev 1.x)?

I'm from Brazil, I do not know how to speak English.

Hi friend can I make a request?

Would this bios update work for the 990fxa-ud5 r5 rev 1.0 motherboard? This is the R5 model number.

Thanks!

Carlos

@darkyoulan & @Salazc - No, the BIOS from this thread is for Rev 3.0 boards only (UEFI)
Rev 1.0 boards are not UEFI BIOS, so you can only use one of these "bootloader" methods

Hi everyone. I have a Gigabyte 990 FXA-UD5 Rev 3.0 motherboard and recently purchased some new hard drives, as my current drives are at maximum capacity, and I needed upgraded drives for better performance. I decided to purchase a Samsung 970 Pro NVMe M.2 SSD as one of the drives, and, at the time, was unaware of the compatibility issue with my motherboard. I performed a Google search seeking a solution and came across this forum post.

Now, after digging around a bit, here and elsewhere, I'm aware that I'm going to need an M.2 to PCIe adapter and a USB flash drive to solve my problem, but, otherwise, I'm lost on what to do from there, and have little understanding of many of the technical terms being used, here on this forum. Could anyone here provide me some assistance and either explain to me, in detail, the process of how to get my SSD up and running with my motherboard, or, link me to a step by step guide (if it exists), on how to do so, which I can easily follow? Also, regarding the file included in the first post of this thread, is it relevant to the process and necessary for me to download?

Any help from someone in the community here would be much appreciated.

Thanks in advance,

Thanks for this release, works flawless with a $5 pci-e x16 nvme adapter and a nice MP510 nvme ssd.
