Installing NetBSD is a relatively complex process, but if you have
|
|
this document in hand it should not be too difficult.
|
|
|
|
There are several ways to install NetBSD onto your disk. If your
|
|
machine has a tape drive the easiest way is "Installing from tape"
|
|
(details below). If your machine is on a network with a suitable
|
|
NFS server, then "Installing from NFS" is the next best method.
|
|
Otherwise, if you have another Sun machine running SunOS you can
|
|
initialize the disk on that machine and then move the disk.
|
|
(Installing from SunOS is not recommended.)
|
|
|
|
|
|
* Installing from tape:
|
|
|
|
Create the NetBSD/sun3 1.1 boot tape as described in the section
|
|
entitled "Preparing a boot tape" and boot the tape. At the PROM
|
|
monitor prompt, use one of the commands:
|
|
>b st()
|
|
>b st(0,8,0)
|
|
The first example will use the tape on SCSI target 4, where the
|
|
second will use SCSI target 5. The '>' is the monitor prompt.
|
|
|
|
After the tape loads, you should see many lines of configuration
|
|
messages, and then the following "welcome" screen:
|
|
|
|
Welcome to the NetBSD/sun3 RAMDISK root!
|
|
|
|
This environment is designed to do only three things:
|
|
1: Partititon your disk (use the command: edlabel /dev/rsd0c)
|
|
2: Copy a miniroot image into the swap partition (/dev/rsd0b)
|
|
3: Reboot (using the swap partition, i.e. /dev/sd?b).
|
|
|
|
Copying the miniroot can be done several ways, allowing
|
|
the source of the miniroot image to be on any of these:
|
|
boot tape, NFS server, TFTP server, rsh server
|
|
|
|
The easiest is loading from tape, which is done as follows:
|
|
mt -f /dev/nrst0 rewind
|
|
mt -f /dev/nrst0 fsf 2
|
|
dd bs=32k if=/dev/nrst0 of=/dev/rsd0b
|
|
(For help with other methods, please see the install notes.)
|
|
|
|
To reboot using the swap partition, first use "halt",
|
|
then at the PROM monitor prompt use a command like:
|
|
b sd(,,1) -s
|
|
|
|
To view this message again, type: cat /.welcome
|
|
|
|
[ End of "welcome" screen. ]
|
|
|
|
Copy the miniroot as described in the welcome message, and
|
|
reboot from that just installed miniroot. See the section
|
|
entitled "Booting the miniroot" for details.
|
|
|
|
|
|
* Installing from NFS:
|
|
|
|
Before you can install from NFS, you must have already configured
|
|
your NFS server to support your machine as a diskless client.
|
|
Instructions for configuring the server are found in the section
|
|
entitled "Getting the NetBSD System onto Useful Media" above.
|
|
|
|
First, at the Sun PROM monitor prompt, enter a boot command
|
|
using the network interface as the boot device. On desktop
|
|
machines this is "le", and "ie" on the others. Examples:
|
|
|
|
>b le() -s
|
|
>b ie() -s
|
|
|
|
After the boot program loads the RAMDISK kernel, you should
|
|
see the welcome screen as shown in the "tape boot" section
|
|
above. You must configure the network interface before you
|
|
can use any network resources. For example the command:
|
|
|
|
ssh> ifconfig le0 inet 192.233.20.198 up
|
|
|
|
will bring up the network interface with that address. The next
|
|
step is to copy the miniroot from your server. This can be done
|
|
using either NFS or remote shell. (In the examples that follow,
|
|
the server has IP address 192.233.20.195)
|
|
|
|
To load the miniroot from an NFS file:
|
|
|
|
ssh> mount -r 192.233.20.195:/server/path /mnt
|
|
ssh> dd if=/mnt/miniroot of=/dev/rsd0b bs=8k
|
|
|
|
To load the miniroot using rsh to the server:
|
|
|
|
ssh> run -b dd if=/dev/pipe of=/dev/rsd0b bs=8k
|
|
ssh> run -o /dev/pipe rsh 192.233.20.195 zcat miniroot.gz
|
|
|
|
Note that "ssh" does not use "sh" syntax. It is a very small
|
|
shell designed for the ramdisk kernel. The first command of the
|
|
above pair runs a "dd" in the background reading /dev/pipe. The
|
|
second of the pair runs an "rsh" command with its standard output
|
|
redirected to /dev/pipe. In ssh, the "help" command will show you
|
|
a list of commands and options (there are only a few).
|
|
|
|
|
|
* Booting the miniroot:
|
|
|
|
If the miniroot was installed on partition 'b' of the disk with
|
|
SCSI target ID=0 then the PROM boot command would be:
|
|
>b sd(0,0,1) -s
|
|
With SCSI target ID=2, the the PROM is:
|
|
>b sd(0,10,1) -s
|
|
|
|
The numbers in parentheses above are:
|
|
controller (usually zero)
|
|
unit number (SCSI ID * 8, in hexadecimal)
|
|
partition number
|
|
|
|
Miniroot install program:
|
|
------------------------
|
|
|
|
The miniroot's install program is very simple to use. It will guide
|
|
you through the entire process, and is well automated. Additional
|
|
improvements are planned for future releases.
|
|
|
|
The miniroot's install program will:
|
|
|
|
* Allow you to place disklabels on additional disks.
|
|
The disk we are installing on should already have
|
|
been partitioned using the RAMDISK kernel.
|
|
|
|
Note that partition sizes and offsets are expressed
|
|
in sectors. When you fill out the disklabel, you will
|
|
need to specify partition types and filesystem parameters.
|
|
If you're unsure what the these values should be, use the
|
|
following:
|
|
|
|
fstype: 4.2BSD
|
|
fsize: 1024
|
|
bsize: 4096
|
|
cpg: 16
|
|
|
|
If the partition will be a swap partition, use the following:
|
|
|
|
fstype: swap
|
|
fsize: 0 (or blank)
|
|
bsize: 0 (or blank)
|
|
cpg: 0 (or blank)
|
|
|
|
The number of partitions is fixed at 8 (by the Sun PROM).
|
|
|
|
* Create filesystems on target partitions.
|
|
|
|
* Allow you to set up your system's network configuration.
|
|
Remember to specify host names without the domain name
|
|
appended to the end. For example use `foo' instead of
|
|
`foo.bar.org'. If, during the process of configuring
|
|
the network interfaces, you make a mistake, you will
|
|
be able to re-configure that interface by simply selecting
|
|
it for configuration again.
|
|
|
|
* Mount target filesystems. You will be given the opportunity
|
|
to manually edit the resulting /etc/fstab.
|
|
|
|
* Extract binary sets from the media of your choice.
|
|
|
|
* Copy configuration information gathered during the
|
|
installation process to your root filesystem.
|
|
|
|
* Make device nodes in your root filesystem.
|
|
|
|
* Copy a new kernel onto your root partition.
|
|
|
|
* Install a new boot block.
|
|
|
|
* Check your filesystems for integrity.
|
|
|
|
First-time installation on a system through a method other than the
|
|
installation program is possible, but strongly discouraged.
