I am a learning student and was going through the FAQ pages which lead me to reading man pages and eventually man 1 intro.
http://www.openbsd.org/faq/faq2.html Lead me to this next link. http://www.openbsd.org/cgi-bin/man.cgi?query=intro&sektion=1 And so, I'm clicking on the links in my webbrowser at the bottom of this page. This page defaults to i386 variants of man pages. I click on intro 4 at the bottom and it's broken. Anyway, I used the drop down menu's at the top of the intro 1 page and got into intro 4 anyway. I noticed that when I switched off of i386 to the amd64 section of the man pages, the into 1 link at the bottom to intro 4 seemed to work just fine. So, I guess this must just be a link problem with i386 intro 1 going to intro 4 only. Charlie
