501-2780 SUN SM52X SPARC MODULE W/CACHE, 3.5
Havn't actually tried netbooting NetBSD yet, I havn't decided if
I want to run it on my Ultra1 instead. Do you think it's
possible to get it running on those, i.e. is it worth the time
trying? If not, I just go for the Ultra1 instead! ;-)

Too bad. Maybe try to get an NDA with Sun wich enables us to
view the documentation and release the code we write, but not
the documentation. I think that what we got with Intel regarding
the Gigabit network driver, or something.
