I am afraid I can't figure out what the reply was or to what.

Even going through the hassle of trying to view the html version didn't
help much.

Ok to recap. You assumed you needed to turn off the computer to install PCIe. You learned PCIe is hot pluggable. You assumed the card had to be plugged into the target machine, you learned it did not.

I was just pointing out why you made those false assumptions and then wrongly designated the information as irrelevant.

Its because I didn't explicitly describe what was so obvious in the video.

I'd normally politely say my bad but in this case I think not.
