@it.omri - Sorry I get buried easily here

Is that all you have, two PCIE Slots? What does not detect second card/NVME, windows or BIOS? If BIOS, does not matter, you aren't booting from that so it would not be visible to BIOS anyway, only NVME with Windows boot loader would be seen by BIOS like this.
You should see it in windows for sure, if not, confirm the card and NVME work on another system

USB 3, from what I re-read above, I think you have to send me the known USB 3 working BIOS then I redo the mod for you.

Happy to report, that all is well...

during playing around with the system i removed the battery from the MB, and used the recovery proccess for the MB, re flashed with the bios you sent me.
and now i have usb3.0 and both drives are visible:)

@it.omri - Great to hear it! So, BIOS was OK all along, and some CMOS issue needed cleared? I guess maybe best to clear CMOS after flash on some boards, and always load optimized too (always, always, always).

Hi,

So you guys say you have a working bios for this board!! Is there some way I can get hold of it too (download link or...)?

I have the same board (z68X-ud3h-b3), but rev 1.0. Windows-insatller see the disk, but not seen and bootable from bios.
Only what to use a single NMVe for booting and running Win 10.
The old Awaard-bios can see the disk, but not support boot from a GPT- formated disk (unless a pre-usb-boot). The new/latest bios don¨t show the disk.
Thought I had to go back for the Award-bios, but You seems like to have a solution fir me too.
Yaeh, this is an old board, but sufficent for a HTPC.

Regards

@Qunaki See post #10, new link added. Flash to U1n first using standard method, if you are on old award BIOS right now. If you are already on U1n, flash this BIOS via Q-flash, clear CMOS once done, enter BIOS, load optimized then save and reboot back to BIOS to make other changes you want.
Make NVME RAW drive (ie delete all partitions, do not initilize etc), then follow all steps in #4 of the "This is what you should do" section of this thread - [Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS

@Lost_N_BIOS. Must have missed that link, thanks.
I'm on U1n, so I go from there. Years since I used CMOS, but I'll follow your good/clear instructions.
I see I have to run Diskpart again and make the disk raw again. Tokk a bit to clear it when it was on GPT (right now it's MBR).

I was about to go MBR and olld Award bIOS (since the disk showed up then), but this is a much better way.
I'll reply how it went. Thanks in advance,
---------------------------

@Lost_N_BIOS. It's up and running.......yeah! Many thanks to you! You are a beast on tweaking bios.
Everything was spot on as you guided.
After BIOS update, and clear CMOS it restarted itself a couple of times before getting me access to BIOS.

Had some trouble 'cause Windows would not install first. This might be my fault in the heat (not choice format first :-)
Diskpart and convert to GPT and then it rocked.
The old os-disk with a corrupt (and non revoverable) Windows still exist. Unfortenately now I realize that I have´t saved the Windows-key for this machine (upgraded from Win 7 years ago). Only have my laptops winkey

This was better than Xmas. I deeply thank you for your support.

-----------------------------

ShowKeyPlus fixed that WinKey part (I both had the old OS and a backup).
The logo is perfekt, but it is also been disabled in bios anyway for my part.
Both BIOS and Windows starts in 10 sek - great. This machine has alwasy been on before. But with this start-time (and usage) I think we will keep it off more, no need for it 24/7.

But the computer seems not to power off - very odd. Never happened before, and I don´t know.why.

@Qunaki - Great to see you made it through all those hurdles and are now up and running Win10 again! [wink

On the shutting off thing, check windows power options, power button setting, and make sure you have it set to power off not hibernate (I think that may be default). If you have that all set OK, it could be a ME FW issue, let's check ME FW to confirm.
Please DOWNLOAD HWINFO64 HERE Once HWINFO is open, look at the large window on the left side, expand motherboard, and find the ME area.
Inside that section is the ME Firmware version, as you see in screenshot below. If you do not see ME FW, you may need to install Intel INF package, or also Intel Management Engine drivers.
If you cannot install ME drivers, or you see 0.0.0.0 or N/A for ME FW version, then your ME FW is corrupted and we need to fix. If this is the case, let me know and I will make you a clean updated ME FW for this system and get you info on how to flash it in

@Lost_N_BIOS - Just found your PM in the junk mail.
[The FW/NVME/Win10 was quite straight forward]
I fixed the power off option after installing.

But I will look into the HWINFO, but I guess everything should be ok. I'm bow and thank you for your help.

Hi, just found this and it seems just what I need! I am trying to update an older machine to an NVME boot drive but have had no luck. It is a Gigabyte Z68XP-UD3 board, but when I try to update to your awesome modded BIOS via Q-Flash it just says "BIOS ID check error"???
If you have any suggestions I would greatly appreciate them!
Thanks, you are doing great work on here!
----------------------------

I should add that I am currently running UEFI BIOS version U1J. It is Beta...

@ktmaniac - I see your thread and was about to reply, but then I see your message above first. What BIOS in this thread, what post #, are you trying to flash to your board?
* Edit - never mind, I looked through all 3 pages, there is no BIOS posted here for you model board, so that is why you can't flash any BIOS from here

@it.omri - Can you confirm, or check, the BIOS I made at post #10, are you still using? If yes, does RealTek audio function properly for you?
@kentaurosk8 ^^ Same, are you using that BIOS I made? If yes, RealTek working OK?
@Qunaki ^^ Same question, thanks

@Lost_N_BIOS No, i sold that crappy board (the most UD3s are junks) but if you remember mine and @it.omri boards were not Z68XP-UD3 as @ktmaniac is but Z68X-UD3R and they have different BIOS.
For my board your BIOS didn't work for more than 20 minutes (rear USB 3.0 ports still were not working) because after i tried to overclock the mobo died and after many tries it came back to life with the recovery BIOS. I reFlashed the stock BIOS and everything work perfect (and rear USB 3.0 ports also).

@Lost_N_BIOS
Still running this board and working great, I have 0 issues with this board (GA-Z68X-UD3H-B3 (rev. 1.3).
But remind you to first upgrade to the latest uefi stock ROM, and before flashing the mod you have to force bios recovery with CMOS battery out in order to clear any changes, only then flash the modded bios
& as I said before... no problem with raid arrays, usb 3.0, RAM at 1600 (using intel XMP, No manual over clocking), with gen3 i-7, nvme module (970 evo plus)*2 on both pcie x16 gen3 populated with drives using adapter (didn't check how it is with graphics card bcz I have no need for it)

@kentaurosk8 - Thanks for your reply.
I was asking due to this users thread, which is the board/BIOS you were using - [Request] GA-Z68X-UD3H-B3 rev. 1.0 NVMe-boot support

@it.omri - Thanks, I thought so! I told the user that too, hopefully he will redo and flash stock BIOS first, then mod.
I doubt he will be able to force recovery, and that would copy over backup to main, so does not sound ideal or needed, especially if backup not already force updated to U1n also. I assume clear CMOS would do what you mentioned just the same
Realtek Audio is the only thing in question here, does yours work properly?

On my specific board, the recovery rom from the dual bios is 1um... even when I'm flashing 1un.. on this specific board it's very important to flash stock rom then recover the bios by force and then reflesh stock rom.
All 4 of my boards of this model had wired issues unless i followed that procces, only then it worked with no issues at all
Every gigabyte board that has "dual durability" bios can enter bios recovery mode by pressing 10 seconed long press on power or reset button.
