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

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.
