Hey guys, I'm cross posting this from the other coffeelake mod thread since this one seems more active.

I've got a bit of a unique situation and I was wondering if I could get some help or advice.
I've got an Asus strix z270I and I'd like to mod it to work with a Xeon E-2288G I recently got my hands on.
The E-2288G seems to be identical to the i9-9900k other than the fact that it supports ECC memory and has a 100mhz higher base clock. From what I've read it seems that if I make the physical modifications to the CPU all that I need to do do the BIOS is add the correct microcode and update the ME firmware to a corporate version that will enable Xeon support.

I downloaded coffeetime 0.85a and used the advanced mode to modify the most recent BIOS for my board, v1205, I had to use advanced mode because it was the only way to add the 906ED microcode required by my processor since it is the R0 stepping. I received this warning message, which concerned me:

"Best way to use ASUS 200-series with 16-thread CPUs (even Xeons!) is manual porting bios from
compatible Z370 board. Automodifying is available for test purposes only.
Contact with CoffeeTime author to recieve ported bios variants for testing or wait this function
will be added."

I ordered a CH341A rom flasher and it should be here today. Can anyone tell me if the BIOS I made with the above modifications should work? Or do I need to get someone to back-port a z370 BIOS for me? Asus made a z370 version of my board that is almost completely identical so if anyone could help me with that I'd really appreciate it

@Lost_N_BIOS i have to take the eeprom out of motherboard and weld it directly to ch341 programmer and detected ok. i make backup (read and save). i modified the backup bios with AIO tool to downgrade to ME 11.7xx, i found a Macronix MX25L12835F chip (in the datasheet seems to be the same pins and 16mb memory), erased memory, writed moded bios and put it in motherboard, tried to boot with i3 7100 but cpu fans power on 1 second, reboot and still power on permanent without video output. also tried with pentium g5400 (coffee lake cpu) and power on 1 second and shutdown (worst than i3). Ok, i thinked maybe the MX ic was the problem and do the same but this time with original Winbond chip W25Q128JVSG, same issue. Ok, now i will try to back the fisrt state flashing backup bios unmodified, but still the same problem! i killed my asrock z370 pro4? :(

@guspaz - What software/version did you use to write, it may be failing due to bad write/incompatible software/version for that chip/ID. Or it could be broken BIOS due to bad mod, sounds like it must be one of these, due to your old CPU not working either.
Upload your original dump for me and I will redo the mod << For this, tell me your old CPU model, and your new CPU model AND SSPEC

For the first chip you mentioned, I don't know for sure, no one has discussed or reported what works here. But I know for MX25L12873F use CH341A v1.31(1.4) (CH341AFree) (This is the name of the folder), ASProgrammer 1.4 or 1.41, or CH341A v1.1.1.32, so one of those may work for as well, all in below linked package
http://s000.tinyupload.com/index.php?fil...213094641136166

For W25Q128JV >>
W25Q128JV - works with 1.18 (read, not write) or ASProgrammer 1.40/1.41 (maybe OK)
W25Q128JV - Colibri ver. 1.0.1.62 confirmed write OK << This is only one I've seen confirmed OK read and write. I say stick to this chip and this software, once I make you fixed BIOS [winik]

Main issue here may be failed writes, or bad mod BIOS, OR bad mod BIOS AND Failed writes AND bad source BIOS (ie bad dump) due to badly dumped/corrupted from the start etc due to incompatible software creating the initial dump.
Do you have a FPT backup of the BIOS region from before you did anything, or ANY previous BIOS backup made with any program, from before you did anything? If yes, please upload for me, I will make you a BIOS

You should connect and Isolate pads on g5400, if you have not already.

@emeraldx86 Try this BIOS http://s000.tinyupload.com/?file_id=00288656704737395495

@dsanke - When you guys do/discuss "port Z370/Z390" BIOS into Z170/Z270, what is really going on for that kind of edit?
Is it just a direct "BIOS region" (entire) swap from Z370/Z390 into the older BIOS? Or is only certain parts of the BIOS region swapped over?
If it is entire BIOS region swap, how do you know what boards/BIOS are compatible for swapping in, is it just basic looking to see if the PCB's look same/similar on the donor board compared to the target board?

@Lost_N_BIOS - Can you make me bios for Asus z170 deluxe and i3 9100f (SRF6N) processor? I tried, but I didn't succeed. Here are the original bios for my motherboard.
z170 deluxe

@Petoparac - What is your old CPU? What is your current ME FW version? Do you have flash programmer?

@Lost_N_BIOS
My old CPU is Intel Celeron G3900.
I think it's ME FV 11.0.5.1189.
Yes, I have a CH341A programmer.

@Petoparac - Since you have flash programmer, dump current BIOS and send to me for edit.
If you have not already erased and written to this BIOS chip with success (bootable) before, then tell me the BIOS chip ID so I can tell you what known software/versions work so write wont fail.

@Lost_N_BIOS - BIOS chip is WINBOND W25Q128FVSIG. I didn't delete the current BIOS and I'm just typing from that computer.
Which version of the software should I use to read and write?

@Petoparac - For W25Q128FV you need to use 1.18 version CH341A software (for valid read only), or use ASProgrammer 1.41, otherwise other versions always fail (at read sometimes, but write always).
For write to this chip, only Colibri (included below) or ASProgrammer has been confirmed working here by others. I believe Colibri has been proven read/write both OK

@Lost_N_BIOS - I read the chip with the Colibri but due to the size I can't post the file here so here's the link: Asus z170 read BIOS

The motherboard is ASUS z170 deluxe
Old CPU is Intel Celeron G3900
New CPU is i3 9100f (SRF6N)

@Lost_N_BIOS i was using colibri v1.0.1 for flashing. i'm sorry, the problem seems to be a wrong welding of the eeprom memory pins in motherboard. thank you a lot.

@Petoparac - What is your LAN MAC ID? It's messed up in this file, I will fix for you. Should be on sticker on side of 24pin

@guspaz - So bad solder? If yes, so you fixed it now, and it's working?
