I wanted to thank the forum for the helpful tutorials, without them I wouldn’t of been able to add this new feature to my existing computers!
The modified bios for the Asus M5 A99FX Pro 2.0 Rev 1.01 that includes nvme support is included.
M5A99FX-PRO-R20-ASUS-2501.cap ← Original bios version 2501
m5a99fx-pro-r20-asus-2501_modified.cap ← Modified bios
I used the MMTool utility in order to generate a compressed DXE section of the bios so that it matches the structure of the rest of the bios guids. I flashed the bios by using the usb utility of the bios. You will need to rename the bios file to M5A99FX and put it a usb 1.1 drive formatted to fat32 with no other files in it. Then use the usb flashing button on the motherboard while the computer is powered down while the powersupply is connected to an outlet. Follow the instructions on the motherboard manual. See page 2-13 of the manual at:
I hope this helps someone outhere!

This is awesome and I can validate it works. I’m using this live right now and it was painless to setup, just do the button press bios update on the board and it will pickup the NVME.
It was such a rare sight I refused to install the OS while having my regular sata drives, I couldn’t believe it was that easy… but it was.
So I started wondering, if I were to setup a raid card with two nvme’s… would it work with this bios?
Hello! Salazc, I had strange problem with your BIOS. It’s funny, but… Old Phenom 1100t booted and worked flawlessly, but newer FX-8350 - NOT! BSODs, no NVMe drive and other bugs. Same config, same board, I swapped only CPU. Of course, I resetted BIOS to defaults, cleaned all contacts, changed SecureBoot and CSM settings… No effect… But with Phenom it works great.
So, I’ve taken 3 NVMe modules from Sabertooth 990FX 2.0 BIOS and embedded them into v.2501. Flashed BIOS via USB Flashback (mo-bo manual, page 2-13). Works flawlessly with my FX-8350.
File didn’t attached to last post. Here it is.

MV, Thanks for including the nodded BIOS for the 8350 it worked perfectly. I’ve had my Samsung 970 Pro nVME m.2 drive for a little over a month now, installed Windows 10 on it when I got it, and was about to try to lean how to mod my BIOS myself. You saved me a lot of reading forums and aggravation. Thank You!

Hi guy, i have a rocket sabrent NVME 2280 with pcie adapter, my speed on test is 1500 on read and 1000 on write, what are your tests? and what NVME do you have? thank you
So, this is going to work with an FX-8370 as well, because you kept the original 2501 code and just added known working NVMe modules you scalped from the Sabertooth BIOS?
(keeps fingers crossed…)
EDIT: Worked like a charm. Thank you MV.

Is there any way to boot from an NVMe on the A99FX? I’ve been trying to clone an old drive over to one and I can’t seem to get it to identify it as a bootable drive at all. Show’s it as a PATA drive but otherwise won’t boot from it.
Yes there is when things r done in the correct way.
Go read again, specially the point 4 of the guide: [HowTo] Get full NVMe support for all Systems with an AMI UEFI BIOS
and ull find out wot u messed up.
