The ``pegasos1`` machine emulates the original Pegasos (later marked I) sold by
Genesi and designed by bPlan. It uses the same Articia S north bridge as the
``amigaone`` machine, otherwise it is mostly the same as the later Pegasos II.
The ``pegasos2`` machine emulates the Pegasos II which is a redesigned version
of Pegasos I to fix problems with its north bridge. Its schematics are available
