I _might_ be able to try it Sunday, but I make no promises. If not, it'll
be December before I can try it. I think 1.3 will be out by then. But I
will try it, just to see if it's ok.

So basically I put a netbsd.ecoff kernel in /, boot Ultrix single user, dd
the file into rrzXb, reboot using "boot -f(0,X,0)netbsd-1.3 n" (this is a
3100), and see if it's fine?

Ok. I think I like this better than dd'ing to the new disk as I can mess
w/ the partitioning setup much easier.

Then, if I just go back to booting Ultrix kernels (leaving Ultrix on the
Ultrix drive), all is well, and I can boot NetBSD on the NetBSD drive.
Nice. A dual-booting pmax. :-) Dual boot is good politically as I'm trying
to convince other folks to re-do a cluster.

Take care,
