#NVME BOOT UEFITOOL MOD#
Our discussion was not necessarily about “how to flash a mod BIOS” as I see it, but more about “how to make a NVME Mod BIOS for Asus” since it was not outlined clearly for that user in the guide, and discussions to sort it all out should not be split into 2-3 topics all to accomplish one task Additionally, this topic covers “Flashing of the mod BIOS” at post #1 step #3 Then save this file as USB Flashback Name - You can get this by dropping BIOS onto FD44Editor if you are not already sure of the BIOS USB Flaskback name, it’s called “Recovery Name” in - Our discussion is 100% on topic, all about creating proper NVME Mod BIOS, see step #2 in my outline (do NVME mod).

CAP at offset 800h or 1000h, depending on your BIOS starting offset after capsule ends as noted in step #3 aboveħ. Open mod bios rom/bin (body) in second tab of hex editor, select all and copyĦ. CAP in Hex editor and go to offset 800h or 1000h offset depending on your original stock.CAP BIOS, this is the end of the capsule, and the start of the actual BIOSĥ. That will be your starting point of the "BIOS Image" itselfĤ. Header size is the size of the actual capsule, and this tells you the BIOS starts after this at 800 or 1000 (generally). If using regular UEFITool versions (ie 25-2x), not NE Alpha (ie 51-5x), then you need to select AMI Aptio Capsule, then look at "Header Size" as shown in the image below. This applies to AMD as well as Intel, so pay no attention that both of these happen to be Intel BIOS For Intel it will show “Intel Image” for AMD it will show “UEFI Image”ģa.
#NVME BOOT UEFITOOL HOW TO#
The offset which body of BIOS starts depends on your particular Asus BIOS and how large it’s capsule is, example of how to tell and both sizes is shown below, the capsule size is usually 800h or 1000h (2KB/4KB) CAP BIOS in UEFITool, expand “AMI Aptio Capsule” and check to see what is the starting offset of the “Body” of the Capsule is, this is the actual start of the “BIOS Image” itself (Rom/Bin)

Then do NVME mod to that bin/rom (body file) per the guide at post #1 of this threadģ. Use UEFITool on the stock.CAP BIOS to extract the body > Right click AMI Aptio Capsule and choose extract body, save as bin/rom does not matter.Ģ. But, see below, I have now did just that, and added images etcġ. I gave the steps in order above, it would be same if I broke that down into numbered step-by-step instructions.
