Same thing with bios mod P9X79_4701
Hello All,
It’s my first post in this very interesting forum.
I went through the subject but many links no longer work.
Is there already a modified bios version for simple “P9X79” in 4801 version that supports ALSO the bifurcation of the white slot (PCIE X8) in X4/x4. I would like to use it with an ASUS hyper M2 card that has 2 M2 slot. I found a 4701 version but prefer the 4801.
Thanks in advance.
Hello, I am trying to get NVME Support working on my P9x79 Mobo version 4801. I have been following the thread here [Request] Asus P9x79 BIOS with NVMe support
but I’m out of my depth on this when I get to this part:
NVMe functionality via ------> NVMe mod to run UEFI NVMe SSDs using module >> NvmExpressDxe_4.ffs dated 04/18/2018 inserted after CSMCORE for this Aptio IV UEFI/BIOS
I have found a copy of the NvmExpressDxe_4.ffs file but I’m not sure where to go from here…
Here is the screenshots from UEFI BIOS Updater (v.180.15):

Welcome to the Win-Raid Forum!
For interested users like you I have written >this< detailed step-by-step Guide.
Good luck!
Thanks @Fernando. I have followed the steps of inserting the NVMe module (NvmExpressDxe_5.ffs) using the MMTool (AMI Aptio UEFI MMTool v5.0.0.7) and saved the result in a new folder (P9X79-ASUS-4801-Mod.ROM.fd).
This is where I’m tripping up… " Don’t forget to re-insert the original capsule and to save the modded BIOS as *.CAP file according to >this< guide written by MeatWar."
I have looked at that thread by MeatWar and cannot understand what I need to do. Is it as simple as renaming the file ‘P9X79-ASUS-4801-Mod.ROM.fd’ to ‘P9X79-ASUS-4801-Mod.CAP’?
The guidance was for him only due to his actions, not general rule.
CAP files are the ones accepted and used with the ASUS USB BFB feature, no other files will be correctly identified and accepted by this Asus feature.
The mod can be directly from the ASUS cap files, that user option (Optional) was to work on the Intel image outside the capsulated Asus file, his choice only, cause boards with USB BFF can be mod and flash like so (Still CAPsulated), no need to extract with UEFI tool.
You have a mboard with USB BFB feature, so use it.
EDIT: You’re lost because you followed a user thread instead and not the dedicated NVMe mod guide on this forum.
@MeatWar - This is the first time I’ve done this hence a bit lost. The reason I was looking at that thread is because the instructions stated:
I’m not sure how to ‘re-insert the original capsule and to save the modded BIOS as *.CAP file’.
I was following this thread [HowTo] Get full NVMe Support for all Systems with an AMI UEFI BIOS
I don’t know or understand the process of re-inserting the original cap which is the next step I need to complete in the guide above as it states:
“Don’t forget to re-insert the original capsule and to save the modded BIOS as *.CAP file according to [>this< ] guide written by MeatWar.”
If anyone can give clarity on what to do here I’d be grateful. Thanks.
@drjarmin
Just to make it clear:
Your quoted text is not and was never part of my Guide about how to get full NVMe support (=start post of >this< thread)!
Question:
Did you remove the capsule header of the BIOS at all? Note: This procedure is only required for ASUS mainboards, which don’t offer the USB Flashback feature!
If you followed my guide and inserted the NVMe module into the original (untouched) BIOS *.CAP file, you can simply rename and save the modded file named “P9X79-ASUS-4801-Mod.ROM.fd” as “‘P9X79-ASUS-4801-Mod.CAP” file, but don’t forget to rename it by using the ASUSRenamer tool before you are going to flash it.
If you are unsure, please attach your modded BIOS or give me a link.
Hi Fernando, thank you for looking into this. Yes, I am sure I’m following your guide. Under Step 1 - Preparation, the third bullet is:
*Only for ASUS BIOSes with the suffix .CAP
My motherboard is an ASUS P9x79 and the latest version of the BIOS file from Asus is called “P9X79-ASUS-4801.CAP” which has the suffix .CAP so I followed the steps outlined in that section using the UEFITool as outlined in the guide.
Is this step unnecessary? I’ve zipped the modified BIOS file and attached as you recommended.
Thanks again, I’m new to this and still learning so apologies if I’m overlooking something obvious.

@Fernando I’ve followed your steps and ignored the 'Extract the body of the original *.CAP BIOS". After I inserted the module, I got a message “Saving secure capsule as unsigned” in the MMTool (v5.0.0.7). Is that an issue? I’ve attached a screenshot and a copy of the resulting BIOS file.
Thanks

Thank you! I’ll try this BIOS, appreciate you sharing it.
I followed this video for my ASUS P9x79 and it worked for NVMe and rebar:
video guid x79 ASUS then MSI
Make sure to run rebarstate and set “32” for unlimited. Also flash from rear panel with PC off and hold down button for 5 sec. Here is my bios file

I have been using the bios Asus Bios P9X79-4701-Mod-NVME-SA-Switch. I have a date of 1-19-19. It works great, I have no performance issues. Other than, I need to keep the surge setting disabled. And, that may be my power source because I have a good power supply.
My question is: Is there a PCIe bios setting keeping my drives from going into sleep mode? I never messed with the PCIe settings.
PCIe settings like ASPM would only have impact on disks connected to a PCIe card storage controller, in this motherboard, other than this edit your power plans in Windows regarding disks.
Some hdd’s power management can also be changed/balanced with some disks utils.
Well, Auto ASPM did nothing. I am using Intel 760p drives with the 760p Solid State Drive Client PCIe drivers. The white paper states it supports both levels of PM. I tested other drivers as well.
I came here because this is the P9x79/ NVMe place where I received the bios
Why didn’t you mention this initially… what i wrote are for standard HDD disks on internal SATA chipset of the motherboard.
Modern SSDs and NVMe disks are often managed by their internal controller and driver if specific OEM model is used/required, not using MS OOB standart drivers.
ASPM is very often disable by default in bios, cause they cant deal with all kind of hw devices, brands and models around in the market.
So its you choice to engage them and see how the system/power management reactes, some do not even boot when some ASPM seetings are modified or some power managment apps stop responding…resuming enabling ASPM in certain systems configurations can be very unstable, specially desktop user builds.
The ASPM setting do nothing on my system that I can find. I tested all of them for several days each. Same with the ErP Ready setting - nothing. I have both hardware switches off. And, I don’t have Asus utilities loaded on my system. I found them buggy.
My PCIe NVMe drives work at full NVMe 3.0 x4 speeds but no power management in Win 7 or 10
