Let Bugger Vance also make a BIOS. Maybe I'm doing something wrong
Can you try this file? Z27XGSOC.F5

Help me please

I successfully flash my mod bios but mobo can't boot debug code error 18

my mobo z270x-gaming 7

Sorry for my bad English

Flash back stock BIOS, then get new mod BIOS, apparently something is wrong CPU related (18 = Identify CPU and Init Cache)

Anyone willing to make a bios for me?

I have a GB Z270 Gaming SOC MB and a few different coffee chips that I can try. If you mod the bios and load it for me, I will flash it with a KBL chip then pop in a CFL and see if it boots. The latest bios got a microcode update near coffee release, which I thought was interesting, but it does not boot.

I was thinking if someone wants to do this, they can just grab the latest bios here: https://www.gigabyte.com/Motherboard/GA-...support-dl-bios

anyone tried to upgrade an ASRock Z270 SuperCarrier board with Intel i3 8350k yet?
I am going to try this at forthcomming saturday and will keep you informed about success (or fail).

Flashed my latest SuperCarrier BIOS 2.40 with all the possible modifications from latest UBU while still running Intel I7 6700k:

Here is BIOS mod @ F5 - if you want F6d mod let me know and I can do later. Please post back and let us know if this works, thanks!

Sometimes that happens with various USB drives, please try copy of the BIOS on another smaller USB drive (FAT32 best) And make sure USB drive is connected to USB 2.0 port on rear of board, not USB3/3.1. I assume the USB 2.0 ones are the two yellow under PS/2

Also, what happens if you try to flash either BIOS I posted with Qflash from within the BIOS?

Attached is version .65 mod, they're both from a thread here on the forums. Maybe this one will work for you? I sent .62 because stock BIOS came with .62, but maybe .65 mod will work?

If nothing ends up working, you can try latest version of @BIOS program, but best to only use that as last resort and after you know you can recover from a bad flash.
To install it you will need to install "app center", then @BIOS, both available on the boards download page in the "Utility" section

@Bugger Vance
Awesome news, I was able to flash the bios's you made for me. What it needed was the standard efiflash program that comes with the F5 bios direct from GB, the modded efiflash you included didn't work.

However, bummer to report that the board does not boot with coffee. It turns on for 1/2 second then turns off and does not go through any post codes. I tried both of your bios files. In this picture you can see I successfully flashed the PCIe patched one.

I tried 8700k with and without the pinmod short on the bottom, neither one worked.

I think its need to downgrade ME version, as Wolf Larsen say. 11.6.10.1196 - must be OK

@THE_FIST - I did not think to suggest original efiflash, good thing you tried! I had not tested either of those modified files, but reports in the thread here say they work, maybe only for certain boards or certain BIOS.
Sorry it does not work on your CPU. Maybe we can fix, due to wrong Intel ME, I can change that! Is your CPU ES or QC, or retail? Asking to make sure it's retail, so we know correct CPUID microcode was applied 906AE=retail

Yes, thanks @Nastojka - I was not sure which ME was required, and asked which he wanted, but no one replied. So I left as-is I stock BIOS ME 11.6.27.3264, per the guide here somewhere I think, it seemed that version was in the OK area.

Just reading first few pages in this thread, maybe 4-6 it looks like you may not get a ME downgrade even if BIOS has old ME in it. You may need a flash programmer and desolder then program, or flash entire chip with Intel FPT possibly, or other full BIOS DOS Flasher.
I do see the flash descriptor in this BIOS is unlocked read/write for ME, so it should be possible with Intel FPT via DOS but you'd have to read around on how to do that.

Here @THE_FIST - New BIOS files, I downgraded both to Intel ME 11.6.0.1126 - hope you or someone can help you figure out how to force flash the ME to downgrade.

I think the Intel FPT and ME thread will get you there
Special: Intel Management Engine
Intel Management Engine: Drivers, Firmware & System Tools

Be careful with this tool, backup your BIOS first (ie Dump directly), so you have a copy of MAC address, serial number in the BIOS, and system UUID

Guide here for flashing ME only (Section 4), applies to any board not just Asus, and you can either use FTK Kit (edit out Asus lines in the batch file) or directly downloaded Intel FPT tools from here (Or edit/view the batch files from a FTK Kit for merefl.bat)

This is the command you want to be using from DOS >> fpt -rewrite -me -f bios.bin
Use a whole BIOS file, not a ME file or ME region dump etc.

Can you give me link how to downgrade ME?

I use UEFITool 0.22.4 (0.24.00 probably OK too, you don't want the "NE" versions) - https://github.com/LongSoft/UEFITool/releases

Open BIOS, open Intel Image area, then you see ME, right click extract/replace


More info about UEFITool
[Guide] How to extract/insert/replace EFI BIOS modules by using the UEFITool

* I forgot to mention, check the "Descriptor" Region above that too, in BIOS where you see on right side ME read/write, if it says NO for write then BIOS flash tools can't update ME


You can modify the descriptor to change this, here is a thread here about it, but I think if it says NO for write then you have to use USB or SPI flash programmer

I found this here after going further and further into the thread. Looks solid...but a pain for now getting all 6 cores to work.
