After installing DQ77MK board in a new case with new drives I want to install Centos 7 but on booting via dvd and choosing install I get the common error
a tpm error (7) occurred attempting to read a pcr value
I've been in the bios setting to BOOT and security and tried every setting. Sometime I get a security warning about the device and sometimes I get the same error as aover but I can't seem to hit the right combination to install the OS.
Does anyone have a screen shot or more advice they can give ? All I am doing is setting up a webserver for fun and this driving me crazy and the board won't accept F2 so I have keep using the switch inside the case. I think the bios is upto date.
Thank you for contacting Intel Communities.
Can you please look at the following thread and let me know if it helps you to fix the issue?

I had already read that. I get the error when disabled and installing centos 7. If I enable I get a security message invalid device on booting. I'm guessing somehow I need to have it enabled but all the setting I use I make no progress.
Does this happen with another OS image or a http://www.intel.com/content/www/us/en/support/boards-and-kits/desktop-boards/000005640.html supported OS for this motherboard?
Have you tried clearing the CMOS and all other BIOS settings? (move jumper to position 2-3 - Configure Mode):

It was suggested I should try another OS other then Centos, I've not yet had time to test that option. But what I really need to know is that the Boot security setting in the bias should look like when installed new hardware & OS. I'm going to be very busy over the next month or so might not get time to push much further on this for a while.

You may also want to https://downloadcenter.intel.com/download/25195/BIOS-Update-MKQ7710H-86A-?product=59044 update the BIOS using the https://www.intel.com/content/www/us/en/support/boards-and-kits/desktop-boards/000005724.html F7 BIOS Flash Update Instructions as it contains some fixes regarding TPM.

That was my first thoughts, I did download the bios update but could find the iflash program, all the ones I tried just unzipped the bios file. I get the menu to press F2, F7 etc but pressing them does nothing. The only way I can get in the setup is to use the manual switch although a few times press DEL has worked.
Probably you can try https://www-ssl.intel.com/content/www/us/en/support/boards-and-kits/000005630.html this other option (Recovery with USB device) to update the BIOS as you won't be required to press any key.
For this process, you only require the .bio file saved in a USB flash drive, therefore; the iFlash is not required as the USB doesn't need to be bootable, the board will automatically find the .bio file saved in the USB drive.
Finally got around to sorting this out today. I'll outline the process for those confused or having a similar problem.
Managed to update the bias version but in the end I don't think that was the problem.
I'm not sure this wouldn't have worked before as I can't remember if I tried it but what I had to do was install Centos in basic video configuration. You do that by choosing troubleshooting option from the Centos menu. I still got the error but the install continued, and as I'm only using it for a webserver this should be fine.
Thanks to everyone who replied.
