Just received this board and I notice it has an extra header not mentioned anywhere in the manual. This is my first build in a few years, so maybe it is something I should just obviously recognize, but I do not.

It is a white 8-pin header next to what is labeled the "chassis intrusion header." It is clearly visible as the only white header in the bottom right corner on this picture: https://www.asrock.com/mb/photo/Fatal1ty%20Z370%20Gaming-ITXac%28L2%29.png" rel="nofollow - https://www.asrock.com/mb/photo/Fatal1ty%20Z370%20Gaming-ITXac(L2).png

Dear Mr.DNA,

Thank you for choosing ASRock.

Regarding your question, this white 8-pin header is for factory debug.

Please feel free to use your system.

Thank you!

Yours truly,

ASRock TSD

" rel="nofollow - In that same photo, there is also an unmarked header just to the right of the chipset heatsink. What is that one used for?
