For the first time in the short SER-on-WRT-era installation is possible completely without Linux and almost without dropping the mouse.
Detailed installation instructions are available at: http://wiki.milkfish.org/index.php?n=Boozy.StepByStep
p.s.: Internal mechanisms have become recently available as diagrams: http://www.milkfish.org/?page_id=5
After fixing bugs in the milkfish GUI files the new release will be tested and published within the coming couple of days.
