Hi,

I was able to make OSF/1 V3.0 run on a DEC 3000/300 that has only
two RZ23L disks (these disks were taken off older machines and
reused on the alpha). Here's what I did:

1. Install one of the RZ23L disks of Machine A on another 3000/300
   (Machine B) which has one RZ24 and already has V3.0 installed
   (root and /var and swap space are on RZ24, /usr is NFS-mounted).

2. Partition the RZ23L on Machine B using disklabel: partition a is
   about 80MB, to be used for root; partition d is about 40MB, to be
   used for /var.
   
   Create a new file system on these two partitions using newfs.

3. Mount partition a of the RZ23L to /mnt and dump Machine B's root
   onto /mnt, with

       dump -0f - / | (cd /mnt; restore -xf -)

4. Edit /mnt/etc/fstab so that root, /var, and swap will be mounted
   with the right devices on Machine A.
   
   Relink /mnt/sbin/swapdefault to the device file for the other RZ23L
   on Machine A.

5. Umount partion a of the RZ23L, and mount its d partion to /mnt.
   Dump Machine B's /var to /mnt, with

       dump -0f - /var | (cd /mnt; restore -xf -)

6. Install the RZ23L back onto Machine A and boot it to multi-user mode.

7. Change the hostname and IP address by running /usr/sbin/setup and
   reconfiguring the network interface ln0.

8. Reboot the machine.
