I can flash it with FPT without issues.
Thankfully SuperUEFIinsecureBoot allows you to execute any .efi file including the modified grub and the EFI shell for FPT, even with secureboot on

Since im now back on my Original bios i have no issues at all flashing with FPT.

Would be awesome if you could edit it for me.

@neovness - OK, well then here you go - http://s000.tinyupload.com/index.php?fil...814985046473661

Please don't send PM's for help on BIOS edits, I can't help with BIOS in PM's. Please make a thread and I will try to help as soon as I can - thanks!
If you appreciate my efforts and are willing to donate to help improve my hardware, gift cards work for me (Amazn, NuEgg, eBa) - send me a PM
I view the forum like this, please bump your thread 1x every 24-48 hours if no reply

Your BIOS works perfectly!
Thanks a ton that you could mod mine.

I do have another question tho:
Would it be possible to mod the CPU Power Limits?
Since i have liquid metaled my CPU, it usually stays quite cool even under full load, sustaining 3.6ghz+ allcore would be amazing, since right now i hit a brick wall at 3.7GHz with the cpu drawing 55W

@neovness - You're welcome, and thanks for the report back!! Good to here you were able to sort out the rest of the stuff in OS that makes this work
I see TC1/TC2/TSP values (currently set to 1/5/10) that you can change that may affect this. This is ACPI Passive Cooling Formula values

I also see Active/Passive thermal trip points (71C/79C) for MCH and PCH (same for both)

Ohh! Maybe found it, but looks to be set to zero....
Long Duration Power Limit
Long Duration Maintained
Short Duration Power Limit

I believe those ^^ are what is often PL1/PL2 in other BIOS

You can change this via grub / setup_var possibly, if not, then use RU - For both, use the (VarOffset/VarName) value, and the VarStore Value tells you what area of NVRAM to edit (if using RU, if VarStore not "Setup" then you can use setup_var)

^^ So, setup, meaning setup_var "May" be able to change them all, if not use RU method, see section 2.2 and make bootable USB with RU program, then read 2.3-2.5

Sorry, yes, I checked current applied value for NVRAM for Long Duration Power Limit, Long Duration Maintained, and Short Duration Power Limit, and all are set to 00

So this is either controlled by one of the other settings mentioned above, such as TC1/TC2/TSP, or possibly in the EC FW

Dear @Lost_N_BIOS and @Blossomcrown
Help me please. I've been struggling for the past week trying to find a way to unlock MSR 0x194 for my 3940XM. (I am also very happy and grateful to @pseudodeed for his VGA Bios mod for K5000M)

Previously I used Thinkpad T430 with 3840QM, with guidance from a kind person, it reached single core 4.2Ghz and all core 4.0Ghz.

I just changed to M6700 one month ago and am very confused.
Please help me,please ! How can I maximize the power of my 3940XM. Please give me a little time. Extremely grateful. Wish you a thousand good things.
