Great! Anything I can do to help? I am just learning how this all works, but I am very interested in helping. > > Wanna bet we're going to get that machine to a sash prompt this week ?

I've been wanting to get this port to boot on this machine for a long time now :) This is going to be a great week!! - Ryan > > Philipp Rumpf > > --------------------------------------------------------------------------- > To unsubscribe: send e-mail to parisc-linux-request@thepuffingroup.com with > `unsubscribe' as the subject.
