@Lost_N_BIOS Thank you very much, look forward to it.

@julianzz - You're welcome, and sorry for the delay! Thanks for complete BIOS package
Here is unlocked BIOS, flash back via >> FPTw.exe -bios -f biosregmf.bin
http://s000.tinyupload.com/index.php?fil...797716022165425

Please confirm for me, you can see all three light effect options + Light bar option in OG advanced and you can change the core voltage offset prefix +/- there as well - thanks!

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!! ***
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don't try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)

*** WARNING *** - This BIOS is user specific! If you are not user julianzz at Win-RAID.com forum, DO NOT USE THIS BIOS!!
If you do, and you are not julianzz, then you will loose your serial, UUID, OG NVRAM, and possibly LAN MAC ID as well.
You have been warned!!!

@Lost_N_BIOS I have tried the unlocked bios and it works well for me , deeply thanks again!

Just wonder this unlock bios works on my own laptop or all GM7MP7S laptops?

@julianzz - Thanks for quick test and report back, great to hear all is working properly and unlocked as expected!
The unlocked BIOS I sent you is specific to your own laptop only, sorry I forgot warning above (editing it in there now, see above), but I did include warning in the BIOS download package
I can unlock all other users GM7MP7S systems, but they need to each give me their BIOS region dumps personally. This is due to serial, UUID etc (system Specific info) is in this region we use for the edit, so if anyone else use then they loose their serial etc.

Please confirm for me, you can see all three light effect options + Light bar option in OG advanced and you can change the core voltage offset prefix +/- there as well - thanks!

@Lost_N_BIOS I can see all three light effect and light bar options in OG advanced menu(the light bar option seems not taking any effect), and I cant change the core voltage offset +/- option (could not change it in the orignal bios either), but I can change it in the "advanced 2-overclocking performance menu-processer" page(same core voltager options available in this page).

Please tell me if you need any more testing information.

@julianzz - Thanks for info. On light bar, I was not sure if your system has this or not, does it have some light bar?
On the Offset +/-, on OG advanced, if you change it to + on the other new Advanced, and reboot, does it then show + on the original grayed out one or not?
Yes, I seen it was gray on original, that's why I wanted you to look at this, I tried one way to un-gray. I can do different edit to try and ungray that, if you want to try, maybe I did wrong way for this system?

@Lost_N_BIOS Yes there is a light bar in my system and I can turn it on/off(no other effects) by using a control center software, so its not a big deal.

For the OG offset +/- option, its also changed when I change it on the new advanced menu.

The only question is when I change it to like 80mv on the new menu, the OG voltage number option could not show bigger than 50(the same problem on the OG BIOS), but its still working on the right voltage(80), not a big deal too:)

The unlocked bios works fine for me, and if you want to inprove it or need me to do more tesing ,plz tell me anytime. Thanks a lot.

@julianzz - So, the light bar is not affected by the in BIOS light bar setting though, correct? If not, then we'll hide it. They'd have to make this work, I can only make visible or not, may only work on certain models
Thanks for info on the OG +/-, I think if I do other way it will be not grayed out for you. If this fails too, one other possible way should work
Yes, I prefer to get things working right, if you don't mind testing a bit Here, please test, this has that +/- change and light bar option back to hidden

Ohh, core voltage offset is min/max 50mv, I don't know enough assembly to find and change that, sorry
! Unless ! @ReousI - did you ever figure out how to change min/max allowed voltages such as this (core voltage offset - there is two in this BIOS, both now visible)?
80mv shouldn't even be working/possible, max is set to 50mv - Ohh wait, I see the hidden advanced one does not have limit of 50mv (only in help text), so do that one allow you to set higher than 50 actual, and the OG one never could set 80 for example?
If you can set 80+ now on the new one, and could not on the old one, we can just hide the OG offset and prefix if you wanted, that way there's no confusion and you only set the one in new advanced area

Please test MFa - and let me know if Offset prefix at OG Adv is ungrayed now or not, this has light bar hide again + change to this only.
Then MFG has light bar hide + different change to Offset Prefix at OG ADV, if above does not ungray it, try this one. There is several combos of things that can gray or ungray this, so we just need to find right combo
It's supressed/grayed originally + hidden by Access Level, so tough to find right go combo I think MFa will do it, that's what I should have done originally and forgot the last change I think, or I thought the other two would be enough.
http://s000.tinyupload.com/index.php?fil...872783068452639

@Lost_N_BIOS Thanks for your work, I have tried both mfa and mfg bios, and it seems the MFG one(biosregMG.bin) is the right combo which ungray the Offset +/- option at OG ADV and made it changable, and both of them hide the light bar option.

For the core voltage offset, just like you said that I could change it higher than 50(like 80) in the NEW ADV, and its working(I have checked the voltage in windows XTU and its actually working on 80 as I set in the new adv), but the OG ADV still shows 50, so its just a wrong number, no big deal, of course you can hide it in OG ADV to avoid this confusion if you like:)

What is more, is it possible to unlock the "BCLK Frequency (pcode)" option? which is in ADVANCED 2-OVERCLOCKING PERFORMANCE MENU-PRECESSOR page, now its 99.780 and fixed, just wonder if I can change it to 100.

Sorry about my english and I hope you can understand, thanks:)

@julianzz - Thanks for testing results! Yes, sorry, I meant to say MG above << So, this is the one we'll use moving forward. The OG Advanced Offset is limited to 50mv, so that is why that's all it can show.
So yes, probably best we just hide this and the offset prefix there, to avoid any confusion for you or others using this BIOS later.

Or!! I can change that, to be the exact same/equal one as the new advanced one and leave it there, so you have that as quick change area and don't have to dig into and find the other later, if you're maybe in hurry and only need to change that.
Do you want to test if that change is OK next?

BCLK Frequency (pcode) is text statement only, to show you the current Bclk. This can only be changed to near 100 by changing Bclk at other areas (if there is bclk change setting, not sure as I type this and I don't have time to check right now, will later)
Bclk is controlled by ME FW, we can edit that, if you do not have Bclk control, and lessen or remove the spread width, that will get it closer to or exact 100.

Your English is fine, I didn't even know it was not your language

* Edit - In Advanced >> ICC, can you see profile change option? If yes, please dump ME FW for me with FPT >> FPTw.exe -me -d me.bin
Also, dump the following so I can more easily build complete BIOS to check, edit, and change things in the ME FW
FPTw.exe -desc -d fd.bin
FPTw.exe -gbe -d gbe.bin << This may not exist, so if error OK

Also, while in ICC, can you see "Spread" and if yes, can you change it?

@Lost_N_BIOS Thanks for your reply, yes I could see the "Spread" option in the icc page and the default value is 47, and according to the describtion, I guess by lower this value to 0, the fclk freq should go back to 100, but unfortunatelly the system failed to start up when I lower it either to 0 or 10(I didnt keep trying other values because every time the system fails, then I have to remove the battery on motherboard to reset the bios to default), so I gave up, 99.78 is ok:)

I dump the me&fd.bin and attached it below, the gbe.bin dumps error just like you said, I also took a picture of the Intel ICC page, hope it could help. Thanks.

@julianzz - I think it's because with than "Standard" ICC profile, you're not supposed to be able to change the spread in BIOS, maybe with that profile I can't in FW directly either I will check, may need to add Adaptive or Overclock profile, or switch default etc.
Yes, once set to 0 the bclk will be more exact. I checked this profile in ME FW tool, and spread is locked and bclk change is disabled, so that would be why it kept failing when you tried to change it.
OK, here is original ME FW you dumped with Adaptive Profile added w/ spread set to 0.00 already, and that spread % change may apply to the standard profile already too, I can't tell for sure.
If it is, great, if not, then change to the Adaptive profile and reboot back to BIOS. If Adaptive is loaded when you get into BIOS already, and Bclk is 100 with zero spread, great. Please in this case, test setting back to Standard, reboot back to BIOS and then see if Bclk still 100 w/ zero spread.

Do not try to change Bclk directly or it may fail on you and make it unable to recover, especially with Adaptive profile and not OC profile, limit is 97.5-100 on the Adaptive profile.
Please only test changing Spread again if not exact 100, it's in increments of 1/100th of 1%, or if bclk already now 100 exact then all done.
^^ If this OK and Bclk = 100 now, then I can make you another ME FW with just the original standard profile, but with these options enabled/set same

^^ That, and even changing default profile to Adaptive or OC, or changing spread only, is not possible due to Intel's stupid restrictions!
If I change spread, I have to enable Bclk changes, and for that I have to add or change default profile to Adaptive or OC, and any/all of those (changes to default, or new profiles added) are all reset/removed on build.
Unless this is FITc bug, I noticed similar in V12 though, so maybe new Intel lockdown crap!

@plutomaniac - Is that a bug in FITc, or new lockdown stuff from Intel since V12 onward, we can't change ICC profiles, or add new etc? Only actual goal here is to set 0.00 Bclk spread
This case I was using v14.0.20+ r5 - (2020-07-06), also tested with v14.0 r4 package before I noticed R5, ME FW in this case = 14.0.31.1120

If Following changes = reset to default on rebuild
1. Change default profile to Adaptive, Bclk change enabled to allow spread adjust, spread set to 0.00
2. Change default profile to Adaptive, Bclk change enabled to allow spread adjust, spread left as-is 0.45 (So user can change in BIOS possibly)
3. Add Adaptive profile, Bclk change enabled to allow spread adjust, spread set to 0.00 (or left as-is), Adaptive profile set as default (forced or no rebuild possible)

Seems no way to adjust away from default 0.45 no matter how I stab it

@Lost_N_BIOS Hi, I have a EVOO-EG-LP4 just like @zamroc9, and was wondering if you would be able to unlock my bios. I attempted to rip it open myself and used your guide, but got stuck on step 10. I didn't know how to make the necessary edits. In the folder are all the files extracted from my bios file up until step 10. drive.google . com/file/d/11usLMP8Hfgmo13uperFoJtePk7ShZGlV/view?usp=sharing (remove spaces between com)
Thanks in advance for any help/info.

Hello, I am a user from China. I would like to ask if you have the BIOS file of mechrevo x8ti plus series gk7cn6s. Thank you

It's not 25Q20CT, that is only 2MB - That GD25B127D is BIOS, but until now no one has replied back to me enough on this chip for me to know for sure what CH341A software can read/write to it properlySo, best bet for now is for you to dump that with Flashrom and let me check the file before we do anything else. Here is Linux Flashrom method - [GUIDE] The Beginners Guide to Using a CH341A SPI Programmer/Flasher (With Pictures!)And here in post #510 is windows flashrom w/ GUI - [Guide] Using CH341A-based programmer to flash SPI EEPROM (34)DO NOT erase or write to chip until I've checked your dump and replied back that is OK Then I will fix BIOS and send to you, and give the OK GO
