Hi,

I just followed these instructions for my Gigabyte Z77X-3DH motherboard, and it worked first time, I am amazed! Now have Samsung 970 NVME 1TB installed and booting :D

I just wanted to say a massive thank you for the information on here, it was very helpful.

Confirmed, works for Asus N751JK laptop, HM86 chipset.

@ViliusK:
Thanks for your feedback.
Does that mean, that you are now able to boot off your NVMe SSD? If yes, how did you flash the modded BIOS?

So far failed with Supermicro X9DRX motherboard. After BIOS mod, the system could only power up. I would get no video, no beeps, nothing...tested with only CPUs and RAM installed. I could not even accomplish the BIOS recovery hot key method by holding CTRL + HOME and powering up with a BIOS USB stick inserted.

Only way I was able to recovery the BIOS was by using logging in on another computer via IPMI (web interface) and using the BIOS update feature.

I'm curious to test if the EIFTOOL.exe changed something else in the BIOS that the MB didn't like. For example, I noticed there were entries removed named "padding" and such.

EDIT 1: As a test, I opened my unmodded BIOS with EIFTOOL.exe, and added in the module per this guide, but before saving it, set it to remove the same module, attempting to make a duplicate unmodded BIOS but saved from the EIFTool. My goal, was I wanted to see if the EIFTOOL might be doing something else to my BIOS that my MB doesn't like. Sure enough, my MB did the same thing, would not beep, no video, no nothing. I then flashed the Source BIOS and the MB is working normally. I suspect the EIFTOOL is changing something else in the BIOS file other than just adding in the module. I'm going to see if I can find a different BIOS tool and try that.

I'm wondering if my BIOS is not a true UEFI BIOS...because the only UEFI functionality comes through an EFI Shell, or there is an option under Advanced to run the PCIe slots in an "UEFI only" mode, but perhaps that is not the same as having a true UEFI BIOS.

For reference my BIOS is American Megatrends Version 2.15.1236

@jfharper - You may need to use another version of UEFITool - link me to your BIOS download and I will check it for you and let you know which version is OK.

Great thanks, man.
Here is the link:
https://www.supermicro.com/about/policie...wareItemID=3239

it should download a file called: X9DRX5_115.zip

it is for MB x9drx+-f here the link to the product page: https://www.supermicro.com/products/moth...00/x9drx_-f.cfm

My BIOS version says AMI 2.15.1236 and Aptio inside the BIOS...just checking to see if there are any incompatibilities before trying.

Cannot seem to locate the download link from AMI website

Fernando, anyway you could send me the modded BIOS? I'm having trouble finding a legitimate link to that tool. AMI, wants me to fill out a form and provide my serial number for something...maybe my MB, etc, and probably have too wait till next week or more to receive a link to the tool.

Nevemind...I think I found one that is OK, and I think I got your image...off to try it out...wish me luck. :0)

EDIT by Fernando: Unneeded fully quoted post removed (to save space within this voluminous thread)

BIOS can't be downloaded from AMI, and that version can be ignored. Only what's shown at Supermicro is actual BIOS version info.
What version of UEFITool were you using? I do not get the usual message about pad-file contents will be destroyed on edit like what you mentioned (I assumed you meant this) But I do see the same you noticed after editing, I tested 22.4, 25.0, and 25.1 and all destroy those pad-files

Best to use MMTool for this board as Fernando mentioned. I tested using 5.02.0024 and it inserted correctly and after saving the pad-files are left in place as they should be.

@jfharper:
Did you ever download the UBU Tool from the developers download page? If yes, didn't you find the Easter egg?
