@MeatWar
Thanks for the answer, do you have a guide on how to remove said strings?
I've been searching in the forums and it seems that some people got to install it by removing the NTFS or TcgPlatformSetupPolicy modules, do you know if these are really safe to remove?

@Fernando
Thanks for the answer, can I post the request in the Bios Modding Request section or should I keep it in the post you linked earlier?

I cannot confirm or deny the results of removing the mentioned modules, from a bios.
On the other hand...it is confirmed that removing the DpcDxe to Udp6Dxe if you don't use UEFI network boot, can be another solution.

Open ur ROM in AMIBCP 4.5, select tab "Bios Strings", press [Remove Strings], dialog box select the language to remove, press [Ok], repeat for all the rest except EN. Save & Exit.
CAREFULL, i did not tested this mod and flashing in ur mboard model. I just tested this method in order to successfully have space in the volume and checked the correct insertion of the NVMe module.
This operation is ONLY ur RISK to take as all mod bios, it can break ur motherboard normal operation.
Make backups of the current spi in the system (Should have the same bios version ur trying to mod) and insure that u can recovery from failures with a SPI programmer or other successfully
reported methods, since ur motherboard does not have Asus Bios Flash Back.
U seem to have no experience in this area of mod... i do not recommend u proceed if u dont know about recovery issues/methods.

@MeatWar
Doesnt "ASUS CrashFree BIOS 3 utility" restore your BIOS when it gets corrupted? Or it requieres the BIOS to be completely functional?
I will follow your advise and I will wait, I may post a request to see if someone had modded this same BIOS before and see if I can get some help.

Hi guys,
I have successfully (I think) modded the BIOS for my ASRock Z87 Pro4 with the UEFITool, flashed it and installed Windows 10 on the NVMe (the only hard drive installed) where it saw the drive right away.
However, the drive does not show up anywhere in the BIOS and so it is not available during the boot process. I have tried different CSM settings to no avail. :(

I would really appreciate some help!
Thanks in advance!

@Markstar

Its normal not to see the physical drive in bios but after the OS had been correctly installed in UEFI mode on the NVMe drive, it has to have a boot entry in bios volumes,
if not the the boot fails because u didn't did the correct OS install or u have a bad bios mod (may not has the OS setup found the destination drive)
The correct settings for a correct OS install is in the guide.

Thank you very much for support @Fernando
I need your help

Asus Z77-A my motherboard 0805 BIOS version CPU i7 3770
I did what was explained in the first message correctly, and I have NvmExpressDxe_4 added to the BIOS.
(I can write with programmer/ not problem flash BIOS 25q64fv)
My PCIe adapter and SANDISK 128SDNEP from out of use after replacement MacbookAir
converted m2 connector mode
windows 10 USB UEFI mode created wth Rufus (UEFI mode partition table GPT)
I saw the thought and format but restart did not go into sandisk boot mode either
Only can be rebooted with usb stick
in my bios settings: Secure Boot disable - Fast Boot disable - option to load UEFI modules - boot off the USB Flash Drive with the WIN Image in UEFI mode.
You can't see a Disk Drive named "PATA" or "PATA SS" within the BIOS.

again me @fernando
I succeeded my request
saw in a different forum address(I could not give an address because I do not know whether sharing is allowed or not )
a different way locate the module CSMCORE
SAMSUNG_M2_DXE.ffs, Nvme.ffs, NvmeSmm.ffs, NVMEINT13.ffs modules (I don't know which one is good for me )
UEFI now has boot capability for NVMe

@MeatWar
Thank you for your reply!
Hmm, I did everything in the guide (check PAD-file positions, etc.) and before the flash, the Windows install would not even recognize the NVMe drive, so there already was a positive effect. I wonder what else I could have missed. I can't try again tonight (mother's day and all), but will as soon as possible.

Any tips about what I could have missed? The only thing I can see is maybe indeed the UEFI: I thought the board supports it (it even has a UEFI guide on the first page), but I don't see an UEFI option that relates to storage (only IDE/AHCI/RAID). However, I can boot USB sticks in UEFI mode (and do, e.g. for Ubuntu from USB).

@pchosm: - I removed the modules Meatwar mentioned without any problems. I use a wifi USB dongle and still use my onboard lan as a passthrough for the wifi.
Mine is the H77 chipset.

We didn't sit behind you....
What about attaching the original and your modded BIOS as *.ZIP or *.RAR archives?

@Fernando: Thanks again for your reply!

How did you flash it?

So are you able to boot from NVME on this motherboard?

Hello,

Sorry if this has already been answered, I searched the threat but could not find anything.

Is there any way to know if the needed nvme modules are already installed in the bios? If so, how?

Thanks!
