This is awfully long, I apologise...

My name is Daniel Seagraves.  I'm a high-schooler, and I collect old 
computers.  I have a few PDP-11s, parts of a VAX 780, an IBM System/36 
(Think you can port NetBSD to THAT?) and a few MicroVAXen. (A 3100, and a 
2000.  The 3100 is online, minako.umtec.com [198.199.189.71] running VMS.  
Shells are available...)  I'm a sysadmin at an ISP.

I just got my hands on the MicroVAX 2000, and seeing as NetBSD supports it 
I thought I'd make an attempt at installing it.
The machine has 6Meg of RAM, an RD53 harddisk (Had to open it to find 
that out), and ethernet (That's standard with these, right?), but no tape 
or removable drives.  So, I went and got the netboot stuff, it's here at 
school and at work, and it works.  I can netboot the machine.  I can play 
around with it (Except for a wierd quirk, I'll explain it later.) OK.
My reasoning here is that I could mount boot over the ether, newfs the 
RD, mount it, untar the distribution there, and reboot from the harddisk.
So, I booted esa0/3, loaded edlabel, that worked, and set the label on 
rd(0,0,0,0).  I have the following numbers:
18 sectors/track, 144 sec/cylinder, 963 cylinders so 138672 sectors total.
Partition A starts at offset 0, size is 120000.  Partition B starts at
offset 120000 size 18672.  Partition C starts at offset 0 and is size 138672.
(I'm assuming the partition numbers are sectors.  Is that correct?)
Anyway, I rebooted, loaded /netbsd over the NFS, and did newfs /dev/rrd0a.
It panicked and went to the debugger, where I had not much of an idea 
what to do (I immediately thought "Cool!  A kernel debugger!  Now what do 
I do with it...) except ask for help.  Reboot looked interesting.  I 
tried that.  It halted.  Fun.  The numbers look interesting I thought 
you all'd wanna see them.  So, I took a logfile of the second attempt.  
It failed in the same manner.  I'm assuming I have my disklabel numbers 
wrong.  Anyone care to tell?

[The little count here just shows as a bunch of ^H characters, so I 
snipped it.  This is also where my little quirk comes in.  When I start 
the machine, it wants it's console commands from terminal port 1.  After 
NetBSD boots, it talks to port 3 (Like my other MicroVAX.  Except it 
wants console commands on port 3) and so I have to real quicklike switch 
ports.  So, a few things may be lost here.  Is there a way to change this 
behavior?]
