Hi Everyone,

Im new here and sorry if im breaking any forum etiquette

I modded my GA Z87X OC (non ‘Force’) according to the guide a few days ago I was able to first install W10 then ubuntu on it. Both OSs were working fine right after the installation. After ubuntu was installed i used it for a while. Seeing how everything was stable in the os, I went to the bios to configure the usual performance settings including some overclocking. During this all time I didnt do anything to windows. After configuring my files and programs on ubuntu I booted from windows to run WDs ssd tool for my 1tb sn750. This was my third time booting into windows. That time and a hundred times after that I kept getting a IO1 initialization failed BSOD. I naturally tried booting into safe mode but it didnt work. I dont have a usb enclosure for the nvme so i have no other way of connecting it to a computer and verifying the integrity of the windows bootloader.

To fix the problem in general i resetted the bios to default settings many times and followed the instructions on step 4 of the guide. I even made slight changes to it just to see if it would work. Nothing.

Setting the sata controller off and disconnecting all sata drives didnt work either.

In the bios I saw csm is set to always enabled and is grayed out.

Im running the adapter card which is a 4x in a 16x slot below my graphics card (asus1070)

I dont want to delete my painstakingly configured ubuntu installation because im new to ubuntu and ive spent a lot of time configuring my installation. Can someone offer some help on whats going on or what I can do? Thanks.

Edit: The bios still sees pata and all the partitions including win boot manager. However, the computer sometimes fails to boot a few times in a row at which point it prompts me into the bios where i set most things to default, boot, then go back to the bios, tweak some clock speeds and boot back safely into ubuntu. I also tried disconnecting everything from the motherboard Except the keyboard and the mouse the display cable and the NVMe SSD. All this was with the ssd in the second pcie 16 (all 16x slots on this mobo

Hi all, I will post my problem and I hope someone can help me:
I have GA-Z87X-UD4H motherboard and I try to add Samsung 970 PRO nvme as secondary hard disk. I bougth a pci-express adapter for install it. I install without problem any game, but when I start every game and try to play, always crash. The crash doesnt terminate the game to desktop, it makes some strange thing like if ssd had been removed suddenly and doesnt appear in the system.

I started to think that some changes needed so I do this:

1. Download a modded BIOS from >here< (Post #13) and install. BIOS recognize the SSD and I installed Win10
2. Install games (now on primary SSD nvme)
3. Start game, and when I tried to play I get blue screen crash and reboot. The code of blue screen is WHEA_UNCORRECTABLE_ERROR
So I tried something more:
4. Follow the guide of this post. Download MMTool, load the bios, find the CMSCORE, browse dx4 and try to insert -> FAIL ("file exceds the volume size")
5. Try it with the small version and the option compress and same error.

Hello, I am looking for the modified bios for the B75 Pro3-m. Do you have it?

@uiketekaes

I think u have another issue HW related, incompatibility, i/o data imput/ram...
The latest mod beta bios presented in that thread #12/13, already has by default from Gigabyte the AMI NVMe module present...
Now u could try to replace this module with the one presented here by Fernando and see how it goes...but i will not point it as ur main issue here.
Remember, there is the standard DXE module and the Smaller one, in sizes.

@ManuelMT21.a

Follow post #6241 as Fernando posted and ull have to do MOD yourself as instructed in post#1

thank you very much for this statement, which may be supported by omgdaniel's report, that he/she didn't get an error message while trying to flash the modded BIOS.
If the related BIOS has not been protected by ASRock to prevent any modification, can you imagine the reason why the flashing of the modded BIOS bricked the mainboard?

@uiketekaes No bios function will be needed for a NVMe disk as secondarry drive. Bios functions are only needed if you want to boot from this drive.

Re-seat adapter card and NVMe disk in adapter card

@Ady DeeJay:
You are right - you should not flash the BIOS, where the Pad-file has been removed.
I recommend to flash the attached BIOS, which has been modified by me using the MMTool.
EDIT on 12/23/2020: The attached BIOS has been removed by me, because this is not the thread where Forum visitors will search for an already modded specific mainboard BIOS.

Money is tight during corona Times. AMD A10 -7870K Radeon R7 ( I know impressive...) 16 GB DDR3 F2A88XM-D3H Nividia Geforce GTX 1050 Ti and 256 GB of Older SSD.

It's a shame there's only 1 Motherboard that takes my "OLD" AMD 12 Core and also simultaneously supports M.2 Drive. I do like games, but, per se I don't play them. I video Edit. And even the most basic of tasks makes After Effects lag.

Will P1 M.2 2280 pAID 70 Amazon. The 900 MB pers second could really really make a difference with my video editing before I can update. Do you think Writing BIOS files over it will work since I have a AMD CPU? I'm in this guys boat and he referred here forum site of the motherboard we have/booting-ssd-pcie-adapter-f2a88xm

I might as well try. Do you know where I can D3H Bios rewrite?

@Fernando - I may not be remembering that correctly, but I do think that's what he told me when I asked, but you may want to ask again to be 100% sure.
UBU_v1_69_17_4 also does not change the file, so I think there is no protection here. I just found same (no protection) on Asrock Z77 Pro3(2.20) BIOS for another user, so I think around this time/era Asrock was not doing protection yet.

I checked @omgdaniel mod BIOS too and I see no issue.
So could be whatever MMTool version he used, which he did not mention, I would use 4.50.0.23 or 5.02.0024 only here.
Actually, it can't be due to this either. I did test build with MM45, MM52, and UEFITool 25.0, all = 100% hex match to his mod.
So version or tool does not matter here, at least not of those three I mentioned.
It could have just been a random bad flash, that is the only thing I can think of, and this would be my guess here. * Edit - Seems he re-tested mod BIOS, and this was indeed the issue

@sinfulprophet - Sounds like faulty, about to die, NVME.
I would RMA this as soon as you can, this is only time I see I/O errors is with dying/dead SSD/NVME

@hudgeba778 - I found that BIOS here - [REQUEST] Gigabyte G1.Sniper 5 Z87 (Update microcode and unlock HPET)

Hello there
I want to do uma by editing asus x541 bios, but I'm doing flash
nvidia is not disabled
I will be glad if you help
Thank you
