Thank you so much maxdarksol worked like a charm!!! I set the secure boot option to "Other OS" saved and then selected to boot from the USB. Strangely the first time I did it I was unsuccessful and the BIOS just reverted to the 0x0 setting. But I tried it again and after powering up the PC second time to see if the command stuck the PC powered off before POST and powered on again, and to my surprise it worked as you can see in the images! Thanks again!

@maxdarksol - Hi, I have a Maximus VIII Ranger (Z170) based motherboard as well. I did everything as you described but TPM still does not work. I am using an i5 7600K processor with the latest BIOS version (3802). Any help from you is greatly appreciated. Thanks in advance.

@theWillow - Hi, did you update the ME Firmware on your Z170-A previously?

@maxdarksol It's the same motherboard as the OP (although with a different UEFI version) so same varstoreinfo as you provided, but I can gladly look it up for different boards if someone can't find it.

@itsakjt I did update it when the whole spectre/meltdown thing was happening, can't remember if I did again later but the ME FW version is 11.8.50.3399 and the UEFI version is 3504 as you can see from the pic.

Just giving feedback here: I followed the instructions of @maxdarksol and have now PTT enabled: https://imgur.com/a/fzHWCXJ A bunch of TPM settings are now also available under Advanced/Trusted Computing in the BIOS menu. Board is ASUS Z170-Deluxe (BIOS version 3801) with a 6700k. I previously updated the Management Engine to the latest version from plutomaniac's thread (11.8.86.3909 H). varstoreinfo was the same as in the instructions. Thanks for helping us out!

@Dogg thanks for letting me know after I enabled it I didn't care to look in the advanced tab in the BIOS. But yeah same thing you saw a whole new menu appeared.

PTT is a feature implemented in the Management Engine (ME), which is built into the chipset. There exist, however, a great many processors that come as System on a Chip (SoC) packages that include both processor and chipset. Support was included starting in 4th gen systems that used SoC packages. Practically all SoC packages for 5th gen and later processors included PTT, as did the corresponding versions of the chipsets for Desktop, etc.

Now, it is important to say that whether a particular motherboard or system has PTT support is dependent upon the appropriate firmware being included, both in the ME and in the BIOS.

I have the same problem as itsakjt. I'm using Maximus VIII formula and after enabling PTT, there is no additional PCH-FW menu in bios. Furthermore using AMIBCP to look at my firmware shows there's no "security device support" option.

This is perhaps an issue with ROG boards specifically?

Hi everyone,

I'm having exactly the same issue as KKS89 here. I'm using Maximus VIII Gene with my 6700k, and TPM still not working after booting into GRUB and then doing a 'setup_var 0x6A5 0x1'.

Can't find any "security device support" option either in AMIBCP.

But yeah, my guess is that this issue might be specific to ROG boards, so maybe there's something we're missing here.

Surprisingly enough, there are PTT settings in the BIOS image (offset 0x6A5 for TPM device selection) but nothing seems to be working.

Asus Maximus VIII Ranger (3401)


TPM Device Selection, VarStoreInfo (VarOffset/VarName): 0x6A6

Security Device Support, VarStoreInfo (VarOffset/VarName): 0xEF0

I just checked 3401 version of M8Gene BIOS, and there is still no Security Device Support option.
TPM Device Selection is still offset 0x6A5 and is still getting reset to 0x0 whenever I set it to 1.

Getting a bit desperate over this... there is a huge bunch of 'hidden' options in setup_extr that are encapsulated into { Suppress If 0A 82 } blocks (including PTT configuration and the whole PCH-FW Configuration block), but to be honest I'm an absolute newbie into BIOS modding so I'm not really confident about doing anything on my own here.

Hi, I'm new here ^_^
I have the same motherboard as the topic tittle Asus Z170A powered by an I7 6700K.
I need to unlock this hidden menu with TPM 2.0 options. But I have no idea how to do that, I tried to follow your tutorial, but as I'm not familiar with that I couldn't get any further. Can any of you guys who already made it to compile this modded BIOS so we can download it and just flash it like any other bios?
I downloaded the files from the link you posted, I made the bootable flashdrive with the uefi files you previous zipped, but when I type (during bios boot) setup_var 0x6A6 it says that command "setup_var" doesn't work. How can I create this "support setup_var command grub"?
Sorry to ask, but its the first time I see this modding thing so I know nothing. ^_^
