PXE boot, USB support and other features which might be of interest are
available on the WRAP boards after a BIOS upgrade (to v1.11, I understand
that most ship with v1.03).
It took me a while to figure out how to do the upgrade, and since
documentation on WRAP is somewhat sparser than for the Soekris, I've
documented what I learned:
As noted, the doc is fairly verbose and aimed at beginners like myself.
(It's also my first wiki, so it might be in the wrong place or something;
apologies if so.)
I hope it comes in useful for someone.
