Hi,
I was using this page a lot: http://www.element14.com/community/community/knode/single-board_computers/riotboard/blog/2014/04/10/riotboard-boot-switches
The title of the page was: "RIoTboard: Part 1: RIoTboard Boot Switches | element14"
It disappeared from the net a couple of weeks ago. First I thought it would come back, but I've given up hope now...
There are many traces on the net to this page still (like element14 : All Content - All Communities), but no real page anymore (not even in the waybackwhen archive). On the link you can still find some form of the blog post, but this is important information that should be added here:[One Stop Place] RIoTboard Platform Glossary
Anyway, I've created a PDF out of the useful information on that lost page and attached it to this post. Hopefully it will prove useful to many more people.
I've colored the table a bit for easier reading, but all credit should go to the original author (not sure who he/she is, but thanks!).
