@Lost_N_BIOS
After for 2 days vacation,I am back.
I had tested the file"meupd.bin" you gave me first.
When I hit “FPTw.exe -me -f meupd.bin”,it prompted "Error7,Hardware sequencing failed".
When I hit “FPTw.exe -desc -f meupd.bin”,it prompted some message below.


I had tested the full bios you gave me.
When I hit “FPTw.exe -me -f meupd.bin”,it prompted "Error7,Hardware sequencing failed".
When I hit “FPTw.exe -desc -f meupd.bin”,it prompted "Error7,Hardware sequencing failed".let's see the pic below.


I think it must flash the full bios for this change.

Oh,I Almost forget to show the result before flashing the modded bios you gave me.

Look at this poor result.The speed less than 400MB/s made me hopeless.

@gloobox - The first FPT command is the ONLY one you can use the meupd.bin file with, this is ME FW, you can't flash FD (desc) with ME FW

The hardware sequencing error 7, not sure, maybe due to if you used AFU before ever?
Ohh,. wait, I know why!! It's because your current FD is not made correctly, due to what I mentioned plutomaniac found that I linked you to in post #75, so before you could flash ME by itself you'd have to flash in the fixed FD

To flash the full BIOS I sent you, you must use this command >> FPTw.exe -f filename.bin
You need to be very careful, seems like maybe you are confused a little about using FPT properly, and Gigabyte has unlocked FD so you can brick your board in one click with FPT!!
Be careful Do not try to force things, and be sure you are writing the correct region with the correct commands

So, here is your options and methods to do this.

Here is two Fixed FD files, one with Strap 9 edit, one just fixed FD (Stock)
https://ufile.io/emj5q8n3

First - Flash fixed FD only (I didn't send you before, this does not have the PCH Strap 9 edit in it, just fixed FD)
FPTw.exe -desc -f fixfd.bin

Or, if you want to apply the PCH Strap 9 fix and fixed FD at once
FPTw.exe -desc -f fixfdstrap9.bin

Then reboot and Flash ME FW
FPTw.exe -me -f meupd.bin

Followed by
FPTw.exe -greset


OR - if still error 7 after flashing in either FD above, then ME Region offset is not correct in FD still, this is not something plutomaniac discussed fixing (only BIOS region offset)
So I'd have to find and correct ME region offset too if above FD fix still gives you error 7 (That would leave only this method to flash with FPT)

Flash entire BIOS at once, this has fixed FD + All things we discussed, ME UPD + Strap 9 edit, it may need renamed to .bin for FPT
FPTw.exe -f Z68PDS3.U1cm

Thanks for before image, now comparing that with previous after fix, yes, that's huge difference and you can obviously tell the fix is applied and working!

@Lost_N_BIOS
Thanks again for your detailed explanation!
I had download the files and hit the order you told me,
FPTw.exe -desc -f fixfd.bin

but it's still prompted error7.
BUT it prompted no error when I hit the order after flashing the entire modded bios you gave me.

So I think we could flash the entire bios for the change so far.Actually flashing the entire bios is more convenient

I still have some question for mod and flash these bios.

1.When I flash the entire bios,could I add the -savemac order for saving the mac of original bios?As with the order below--
fpt -f bios.bin -savemac

2.About modding FD/ME/bios of these mobos.

I.I had fix the FD of gigabyte bios.and next step what I do is to change the Strap 9?And if I just modded the change could I click Build Image directly,and flash the outimage.bin?

II.As for updating the ME fw,Let's see the Guide D3.4 and D3.7,Could I take the latest ME.bin directly from the the Repository pack and replace the ME Region.bin?

III.About D3.11,I think it a little difficult for me to manipulate the verification.Which software you choose to compare?

I thought maybe writing in fixedFD by itself would still get error 7 too

Yes, flash entire MOD BIOS, that will fix the FD and ME all at once, then after that writing ME FW region alone should be OK

The FD Fix is to correct BIOS region location in FD at bytes 44-46h, change 00 00 to 18 01 80 01, in case you want to fix and flash any other full BIOS later (For this case BIOS region starts at 180000, thus the 18 01 80 01, but others may vary)

Yes, flash entire BIOS is more ideal, especially since Gigabyte has unlocked FD. I would always correct the FD for BIOS region, in case anyone else use the BIOS later and try to edit BIOS with FITc and or flash FD/ME or BIOS region with FPT

I don't know if -savemac works in this case. Only you can check. I Don't see MAC in BIOS, at least this board does not have GbE, but MAC May be in NVME region too, I'm not sure.
It's probably stored onchip FW in this board. Dump your BIOS and check for MAC via UEFITool hex and text/unicode search (without the : semi-colons)

Yes, once you fix FD, you can build image with FITc. Follow any steps in the guide that are suggested too, I would do FW Update and all suggested additional changes there.
Yes,you use ME FW from repor, and replace in decompressed folder before you re-open FITc and rebuild outimage. But you must follow the guide properly and fully.

I compare XML with Microsoft XML Notepad 2007, Open one xml then go to menu tab and in View you will see Compare at bottom

@Lost_N_BIOS
My math sucks,I stared at it for several days too.

"The FD Fix is to correct BIOS region location in FD at bytes 44-46h, change 00 00 to 18 01"
But I saw the bios you modded was 80 01.


According to plutomaniac's Guid,the bios starts at 180000h,so I think it should be 80 01,was it right?

@gloobox - Sorry about that, I must have been tired! 80 01 is correct (it's backwards/little endian 180000)
I will edit above so no one sees that only and carries on

HI. How did it end? Will you solve this problem further? Because I think now the demand will go to this BIOS. I updated the BIOS on UEFI and yes, my speed also dropped 4 times. Please, there is no one else to deal with this problem besides you.

@Lost_N_BIOS
Hi!There's some problems I met these days about these method.
1.I found not all the Z68 mobos of GIGABYTE had these setting showed "00: 4x1 Ports 5-8 (x1)",and some of these had showed the default setting "11: 1x4 Port 5 (x4), Ports 6-8 (disabled)",such as GIGABYTE Z68AP-D3,but they also had PCIE X1 speed in the second pcie 16x lane.
Although I updated the ME firmware,it still had the problem.


2.About the mobo SOYO B85-BTC,it owned 3 pcie 16x lanes.The second and the third pcie 16x lanes all had PCIE X1 speed.
I had set "11: 1x4 Port 5 (x4), Ports 6-8 (disabled)",and flash it.But the second and the third pcie 16x lanes could not recognized the nvme SSD at all!I think the port of the second and the third pcie 16x lanes belong to the ports 6-8 which was disabled by the setting I made.But I could not mod the port setting such as "1x4 ports 6 (x4),ports 5&7-8(disable)".

@Vladimirusnt
The problem of the mobo had been sloved. you could download the file modded by Lost_N_BIOS and flash it.

@yabay

I have done the same thing for Gigabyte 990FXA-UD7 rev 1.0 (Award) to add Nvme files by installing rev 3.0 (AMI) bios. The M.2 drive worked, but all Sata ports does not work, and the graphics card only works at x8 speed. Sadly I have reverted to the original bios unfortunately. 3 years passed, maybe you have replaced your mainboard but, have you checked those as well?
