First of all I would like to thank Fernando and all others for all their hardwork and many years of effort in this NME boot project
I have an Asus P8Z77VLK on bios 1402
I followed the instructions on page one of this thread and made 2 bios mods
one with the MMTool and the other with the UEFITool
I compared these 2 modde bioses with hdx and they were identical to each other

next i checked a mod bios with original bios for any "pad" file differences using UEFITool and did not seem to find any "PAD" difference either additions or deletions
It is funny a search for "pad" does not show any result in UEFITool but pad files are present

After all this I am still scared/hesitant to flash my modded bios and would like to be 100% sure nothing humanly detectable is wrong
In that regard I hope Fernando would be willing to take a look at my modded and original bios and give me an opinion
Thanks again for indulging a yet another newbie
Here is a folder containing the 2 bioses

Hi, I am on flashing BIOS back after NVMe modding for HP Compaq 8200 Elite sff. I am stuck with this. What manual/procedure I need to follow to make new BIOS sucessfull load ? I am placing two Bios BIN files. Original J01_0233 and modded one for NVMe boot adjustment. Would be great to have my modification for modded bios extra checked.

@Fernando: My sincerest apologies

There should be no password as is in the other file
I inadvertently put one on, when checking to make sure file was under 6mb
Here it is again and I made sure to check for no password.
Thanks again dfor taking the time for this
I would pm you but cant due to new status, but i have pp'ed you for you excellence in this and all matters

EDIT by Fernando: Fully quoted post replaced by directly addressing (to save space within this voluminous thread)

Thank you for checking my BIOS modding load. I am however completely lost in how to upload modded BIOS to my HP Compaq 8200 Elite sff. I tried to follow link messages with may tries with different tools however no success. I do need more helping hand.

Yes, and what is more I have two HP 800 G1 sff ones and I followed the upload description with modded BIOS. Both of HP 800 are stunting. They are jut WOW ones. They boot with NVMe without any issues.

Finaly not being able to flush back the modded BIOS I just used DUET_EDK2020_REFIND.
Procedure used:
- make USB with USBSetup following all steps except of DUET (so only CLEAN, FORMAT, BOOT and REFIND)
- use: default_selection Microsoft
in a file refind.conf (@ USB_DRIVE:\EFI\Boot)

Update BIOS with its HP latest release J01_0233.BIN using HP dedicated for HP Elite 8200 sff tool

HP 8200 boots without user action after marking USB boot option in BIOS. Than I used Mini Partition Wizard for coping partition from USB (made with DUET_EDK2020_REFIND) to HDD. Now HP 8200 starts itself without any user action. Not the very efficient way around however works.

Dear Fernando,
I have Gigabyte motherboard with H81 Chipset. Model no .H81M-DS2 ( Ver 2.0 ). I have modded bios with NVMe support , after the process it shows additional PAD file in it. Should I use this for for flashing or avoid using it ? Files have been attached for your reference.
BIOS.BIN --- Original BIOS
8JUN21.rom --- Modded BIOS with full NVME support DXE

I used UEFITool v 0.28.0. Image shows listing of PAD File entry .

Thank you in advance.

@VU2JRT

First update all in UBU, then use AMI MMtool and insert small dxe module. No more PAD file.

Hello again!

Thanks to Fernando (God bless you!), 3 years ago I modded the bios of my old Gigabyte G1.Sniper 5 motherboard to boot from SSD/PCIE using a Samsung SSD 970 Evo M.2 2TB and it's still working like a charm!

Now, I would like to know if it's possible to do the same on a ASRock Z68 Extreme7 Gen3 (preferably) or a Gigabyte G1.Sniper 3 motherboard?

Here are the BIOS files:

Kind regards,

The Asrock is here already NVMe mod: [OFFER] Modded BIOSes for all ASUS Z68+P67 MBs (NVME+microcodes)

The G1 Sniper3 u can use the small DXE module.

EDIT: Sorry, didnt notice it was the 7 GEN3, here u go, the L2.33A Beta with mcodes updated and NVMe module (Nothing more updated/other modules).
ASROCK Instant Flash from UEFI ONLY not OS environment, user OWN risk as im not responsible for any system failures due to provided files.

And here the G1 Sniper3 F8n Beta with mcodes updated and NVMe module (Nothing more updated/other modules).
GigaByte Q-Flash from UEFI ONLY not OS environment, user OWN risk as im not responsible for any system failures due to provided files.

Hi MeatWar,

Thanks for your answer!

Sorry but I cannot find a mod for my ASRock Z68 Extreme7 Gen3 in: [OFFER] Modded BIOSes for all ASUS Z68+P67 MBs (NVME+microcodes) - can I use Asus for my ASRock?

For G1 Sniper3 (and ASRock Z68 Extreme7 Gen3 as well) I want to use one of my old Samsung SSD 970 Evo M.2 2TB - Form factor M.2 (2280).

Thanks,
Ady

@Fernando Thank you for providing this informative and detailed tutorial...:)

When I opened my original bios Dump using UEFI Tool 0.28.0, it shows the below message...

parsevolume: unaligned file 17088572-377F-44EF-8F4E-B09FFF46A070


However, the error was gone when I open the modded Bios (after inserting the 'NvmExpressDxe_4.ffs' and saving it as new file).

Is it normal? MMTool Aptio does not have the option to show those messages.
