Re: Fujitsu Primepower 200



That really is a pitty...
Does this mean that there is only one possibility : change the source (and
recompile) the Debian SPARC kernel according to detailed specs which I can
hopefully find somewhere on the net ?

If this is the way to go, I'm ready to try it. I've never done this before
(changing source, recompiling a kernel), but I'm not afraid of a nice
challenge now and then. I guess you and other members on the list are ready
to give me help when I need some.

There is some more info on
