$NetBSD: README,v 1.2 1995/11/30 00:58:30 jtc Exp $
NetBSD/mvme68k port README for NetBSD 1.1
supported environment:
Motorola makes a number of m68k VME cards. This port
currently only works on the m68030 based VME147 card (diskless only
for now).
requirements:
- VME147 card
- a machine to connect the console to
- network connection
- NFS server (to serve root and swap)
future plans:
- VME147 scsi disk support
- hopefully, support for the VME162 card
how to boot:
Booting NetBSD/mvme68k on a VME147 is somewhat painful because
the ROM doesn't know how to talk to the ethernet chip. I have solved
this problem by downloading a bootstrap into RAM via the console line.
First, you will need a mvme68k NFS mountable /usr and root
directory. Version 1.1 of NetBSD/mvme68k consists of the following files:
export_exec_mvme68k.tar.gz: /export/exec/mvme68k files (mount on /usr)
export_root_mvme68k.tar.gz: /export/root/mvme68k files (mount on /)
domestic_mvme68k.tar.gz: domestic crypto stuff (restricted to US)
README: this file
These files can be ftp'd from ftp.netbsd.org in mvme68k area of the 1.1
distribution.
First extract the files in the proper place on your NFS server.
Then get the following files: /export/exec/mvme68k/mdec/netboot and
/export/exec/mvme68k/mdec/sboot. Copy netboot to /tftpboot/boot.mvme68k of
your NFS server machine. Make a symbolic link from the hex encoding of your
IP address to that file. For example:
lrwxrwxrwx 1 root 11 Apr 13 17:27 80FCA93F.147 -> boot.mvme68k
[80FCA93F is the IP address (128.252.169.63) of my vme147.]
Make sure you've got the right info in /etc/ethers and /etc/bootparams
on your server.
Now, bring up your 147. You should have the "bug" prompt:
COLD Start
Onboard RAM start = $00000000, stop = $007FFFFF
147-Bug>
Make sure the "stop" looks ok (if you've got 8MB you should have the
same value as I). Also make sure the clock is ticking:
147-Bug>time
Sunday 5/30/27 16:25:14
147-Bug>time
Sunday 5/30/27 16:25:15
147-Bug>
Looks good. you now need to download "sboot" into RAM. you can
either do that through the console line or through a 2nd serial
connection. I have my 147 connected to a sun4/110 and I access it via
"tip". to load that way do this:
lo 0
~Ccat sboot
go 4000
which will look like this:
147-Bug>
147-Bug>lo 0
~CLocal command? cat sboot
away for 11 seconds
!
147-Bug>g 4000
Effective address: 00004000
sboot: serial line bootstrap program (&end = 5fd8)
>>>
Now, if you want to do it through serial line 1, then connect serial
line one to a machine. At the "147-Bug> " prompt do this "tm
1"... you should then login to what ever machine it is connected to.
Then hit "^A" to escape to Bug. do "lo 1;x=cat sboot" ... then when
that is done you can reconnect "tm 1" and logout. Then do "go 4000"
and you've got ">>> " prompt of sboot.
Once you've got the ">>> " prompt you can do commands such as:
"b" - boot "netbsd" multiuser
"b gennetbsd" - boot "gennetbsd" multiuser
"b -s" - boot "netbsd" single user
"b gennetbsd -s"- boot "gennetbsd" single user
A typical boot looks like this:
sboot: serial line bootstrap program (&end = 5fc8)
>>> b
le0: ethernet address: 8:0:3e:20:cb:87
My ip address is: 128.252.169.63
Server ip address is: 128.252.169.2

good luck!
step by step installation directions:
[0] get the distribution
[1] unpack export_exec_mvme68k.tar.gz: gunzip, tar xfp, in /export/exec or equiv
[2] unpack export_root_mvme68k.tar.gz: gunzip, tar xfp, in /export/root or equiv
[3] run "MAKEDEV all" in NFS /export/root/mvme68k/dev directory
(may have to add /etc, /usr/etc to the PATH line of MAKEDEV if
on non-NetBSD system)
[4] fix NFS root's etc/fstab
[5] fix NFS root's etc/myname (put your hostname in there)
[6] fix NFS root's etc/hosts
[7] create the file etc/hostname.le0 with "inet HOSTNAME" in it (replace
"HOSTNAME" with your hostname as per etc/hosts)
[8] create etc/defaultdomain with your YP domainname (if using YP)
[9] adjust etc/localtime symbolic link as needed
[10] create etc/mygate with your default router in it (if wanted, also
consider turning off routed in etc/netstart)
[11] create etc/resolv.conf (if wanted)
[12] make sure the mount point for /usr is there
(e.g. mkdir /export/root/mvme68k/usr)
[13] make sure the var/yp directory is there if you want to run YP
[14] boot as described above
[15] install domestic stuff if in US
[16] have fun
