I modified my first post to attach the picture that you can't see. But please instruct me on how to insert the attached jpg to the position I want. Couldn't find instruction in "Help | Posting".
In the picture I present, the darker items are not in blue, but in grey.
This picture is taken from the mother board's manual, not taken from the monitor's screen at boot. Actually, I have not used this mother board. Only read the manual. So, maybe the darker items are, as you said, in blue when seen on a monitor's screen at boot. I don't know.
