I'll check that out, Nick - thanks.

Thought I'd close the loop on this one. I used the command mbr2gpt in the Windows pre-installation environment to convert the disk to GPT. Booted right up off of the NVME after that. Cool !!!

Thanks! Chris

Fernando, big thanks for a great faq!
I try to do it, but I ask to verify my job please.

my first post on this forum.

i am trying to mod bios so i can boot from m2 nvme ssd (with pcie-adapter). but i am having problems. i am using MMTool v4.50. because inside UEFITOOL v0.27 i saw PAD-files

1st problem: i dont see any CSMCORE line in bios file.

2nd problem: when trying to insert FFS-file in DxeIpl line, then i get: error in inserting file (tried the normal and small FFS-files, in INSERT AS IS and INSERT COMPRESSED modes)
DxeIpl is the only entry with DXE in it.

my bios-zipfile has 2 maps. DOS and UEFI. tried both bios-image-files and get the same error.

my mainboard: supermicro X10DRH-CLN4, bios version 3.2 (latest bios) https://www.supermicro.com/en/products/motherboard/X10DRH-CLN4
bios-zip file is 9,50MB big

i am attaching 2 report files from MMTool v4.50 and 2 report files from MMTool v5.02. all these report files are made without doing any mod on bios-image-file

Hello.

I have the notebook ASUS G771JW.
I have a question about saving the source BIOS file.

What is the best way to get the source BIOS file for future modification:

1) Should I download the final version from ASUS site (in my case it will be 2.11 version which can be downloaded from here https://www.asus.com/ROG-Republic-Of-Gam...pDesk_Download/)
2) Or should I get my original 2.11 BIOS using an AFUwin64. If I get it right I can save my current version of BIOS using it.

Thanks for any help!

I have attempted to insert both types of NVMe modules in the following bios for a Gigabyte GA Z77n Wifi Bios version F3 and I get a lack of space error using the AMI UEFI tool. Can you help with this based on the comment to request help with the problem? "If there should not even be enough space for this small-sized module, I recommend to post your specific BIOS modding problem into this thread and to attach the related original BIOS as *.ZIP or *.RAR archive file (if it should be bigger sized than 6 MB, post the download link). Then we will try to help you"

I've finally made it. My SSD works as a boot device and my Win10 was cloned on my 970 Pro SSD.
Everything works, but I've made speed tests using CrystalDiskMark 7 and the results were a little bit disappointing.

Look at this:
https://yadi.sk/i/_cy4Rmyb41lZHw
Only 1 500 MB/s whereas all internet tests show not less than 3 400 MB/s. What is the problem? Why does it work not on it's full speed?

Excuse me, @Shergar ; is the original system installed on a MBR or GPT table partition? I've seen before Win10 systems installed on MBR format..., i wonder if that is your case.
Wich brand & model is your NVMe---PCIexpress adapter?

EDIT: I'm sorry, i saw that .jpg..., i think 1,5gb is the right speed for a NVMe---PCIexpress adapter, obviously the adapter wont give you the same marks as an M.2 port. Compared to a sata port you're geting more than 3 times sata speed!

@AvenocturnO:
Shergar wouldn't have been able to boot off the NVMe SSD, if it uses the MBR partition scheme.

@Fernando...can you take a look at my case with supermicro x10dhr-cln4? please ?

and my next question is: what is the reason for advice using MMTool v4.50? why not vesion 5.02 of MMTool??
i am asking this, because version 5.02 shows more entries with DXE than version 4.50.
just look at the report files of MMTool, please

EDIT 1:). i succesfully installed win 10 to m2 nvme (adata XPG SX8200 Pro 256GB). but after 1st boot i cann't boot into m2 nvme. neither is there an option in bios te recognize m2-drive...obviously bios mod needed
