@Fernando:
Thanks for your reply! Once I noticed the POST freeze, I removed the SATA3 PCIe Add-On card, like it was before, and it still gives this freeze at the end of the POST. It should work, because it worked before. My question is why can't I get it to boot the NMVe properly anymore? Nothing's changed of the hardware. I don't know what to do. ASUS won't update the board anymore since it's too old. Is it possible to somehow obtain a pre-made BIOS with the NMVe module inserted? Maybe I've done something wrong inserting the .ffs module?

Here the latest BIOS for my system: v2104
Thanks very much in advance for any help! :)

Wot was the controller brand/id on that SATA card? U do know that u have a Marvell SATA onboard controller...

Here is the latest bios v2104 again with the NVMe dxe driver module and all other updates available. We can try another 3 different mods besides this one
Try it and report it back, ONLY USB Asus BFB.

I have an ASUS ROG G751JT laptop.
I attempted to mod the rom file to get my bios to support NVMe, and everything seemed to be fine and work exactly as the instructions stated, but the only difference is when comparing the modded file to the source, it appears to have added one pad-file.
Per the instructions, is says not to use this modded bios if that is the case.

What should be the next step in this? can the extra pad-file be manually removed without an issue?
New to doing this.

Thanks!

Hello Fernando, hello everyone!

I have an ASUS Transformer 3 Pro T303UA laptop.

I'm trying to modify the rom file to get my BIOS to support NVMe SSDs, but unlike the BIOS of ASUS ROG G751JT or ROG G771JW laptops which have already done succesfully before in this thread, there is no such a module named "CSMCORE" and the only module I found with the letters "DXE" within its name was "Dxelpl". I tried to insert "NvmExpressDxe_4.ffs" and "NvmExpressDxe_Small.ffs" using MMTool 4.50.0.23 but both of them failed with a message "Error in inserting file"!

Could you please look at it for me?

Thanks a lot!

@Fernando: Thank you Fernando! That's weird, because according to ASUS's introduction of T303UA, both SATA3 and PCIE SSDs can be used, inside my T303UA was a 256GB SanDisk X400 OEM SSD(SATA3) installed, I replaced it with a WD BLUE SN550 NVMe SSD, but it't won't show in the BIOS at all, the same thing happend to a 970 EVO Plus NVMe SSD, that leads me here.

Can the AMI NVMe DXE Driver inside the original BIOS be replaced with the "NvmExpressDxe_4.ffs"?
If yes, I guess just Right-click onto the File GUID: 634E8DB5-C432-43BE-A653-9CA2922CC458 as you already marked for me, and choose the option "Replace as is..."?
Please correct me!

Thanks for your help!

@Fernando:
I did restore my old setup (removed the new SATA3 expansion card) like it was before. And still I get this freeze at the end of the POST. That's why I replied here, because I don't know why it suddenly doesn't want to boot anymore, despite the exact same configuration. The hardware is 100% identical as it was in a working state. Is there a chance my M.2 SSD is not functioning properly??

With stock 2104 BIOS it won't boot of this M.2 SSD, but when loading a Rescue WinPE BootDisk from USB it does see the M.2 drive. It's my BIOS that won't start booting (POST freeze) when the .ffs module is inserted. Is there a way to fix this?

Hi BIOS Modding Gods,
I tried to use the tools myself but when I opened the file using the uefi tool it shows me image sections with invalid DOS signatures. I could not open it using mmtool as it says its not an aptivo rom.
After I used uefitool and inserted the nvme dxe driver, it erased the pad-file right after it. Instructions said not to try to flash and to post on forum so here I am.

Can someone please help me mod the bios so I can boot to nvme?
Link to official MSI bios: https: // download.msi.com/bos_exe/mb/7850v18.zip
If not too troublesome, can you tell me what I did wrong with the tool? Or how it could be fixed? Is it just extracting the pad-file and putting it in behind the dxe file again?

Thanks!

UPDATE: Nevermind. I used the wrong MMtool version. It looks like this should be correct now.

Thank!!, Flashing success on P8H77-V, altho idk if the nvme will work cus I dont have that rn
Edit: here is the mod nvme bios (DONT USE EZFLASH, use ASUS EZ Update (AI Suite II)

Hey all, just thought I'd report back that this is now up and working on the Supermicro X10DRH-iT board with Debian 10. For further hardware I used multiple Supermicro AOC-SLG3-2M2 2 slot nvme adapters. I also have six SATA drives installed, (non-raid) that didn't interfere with anything.

With the mod installed, it's possible to use the create new boot device functionality in the bios and direct it to the UEFI boot file on the nvme drive. I set that as the primary boot device and all is working, though I did have to disable the UEFI shell as boot device to stop me constantly getting kicked into the UEFI shell at boot.

Note that I didn't attempt to install to the nvme drive, I created a debian installation on a test rig and then transplanted the drive.

Anyway, thanks for all the help, great mod! I'm now off to reconfigure my infiniband on the new install.
