A lot of this documentation is really pretty worthless, because it only talks about the sabre boards. I don't really need to know which dip-switch to set, but which line is begin set to what value, and why. Also, all the references to changes to the manufacturing tool, (like diffs!) are worthless unless you indicate which manufacturing tool revision is the base.
Basically, this is pretty poor. I have "liked" the post, because I like it that people are trying. Still FS needs to do better.
