.Pp
|
|
To install or upgrade
|
|
.Nx ,
|
|
you need to first boot an installation
|
|
program and then interact with the screen-menu program
|
|
.Ic sysinst .
|
|
The installation program actually consists of the
|
|
.Nx
|
|
kernel plus
|
|
an in-memory file system of utility programs.
|
|
.Pp
|
|
The installation methods are:
|
|
.(enum
|
|
Installation from an existing
|
|
.Nx
|
|
or
|
|
.Tn IRIX
|
|
system by booting the
|
|
install kernel from an existing file system.
|
|
.if 0 \{\
|
|
.It
|
|
Copying a bootable diskimage onto the beginning of a disk and installing
|
|
onto that disk. See the
|
|
.Sx Diskless installation
|
|
section later in these INSTALL notes.
|
|
.\}
|
|
.It
|
|
Installation in a diskless environment. This means that you will install
|
|
your entire system onto a remotely shared disk.
|
|
.It
|
|
Booting the install kernel over the network and installing onto a local
|
|
disk. The beginning of the procedure is similar to diskless installation,
|
|
but you will eventually end up writing the system onto your local disk.
|
|
.if 0 \{\
|
|
.It
|
|
Using a helper machine with a SCSI controller to copy the bootable
|
|
diskimage onto the beginning of a disk, and moving the disk to the
|
|
target machine. See the
|
|
.Sx Install via diskimage
|
|
section later in these INSTALL notes.
|
|
.\}
|
|
.enum)
|
|
.Pp
|
|
You should familiarize yourself with the console PROM environment
|
|
and the hardware configuration. A good place to study PROM tricks
|
|
is the IRIX "prom" manual page.
|
|
Be sure you know how to print the configuration of your machine,
|
|
and how to boot from disk or network, as appropriate.
|
|
.Pp
|
|
To boot from disk, use:
|
|
.Pp
|
|
.(bullet
|
|
.Ic "All machine types:"
|
|
.Pp
|
|
.Dl ">> setenv systempartition scsi(0)disk(X)rdisk(0)partition(8)"
|
|
.Dl ">> setenv osloadpartition scsi(0)disk(X)rdisk(0)partition(0)"
|
|
.Dl ">> setenv osloadfilename netbsd"
|
|
.Dl ">> setenv osloader boot"
|
|
.bullet)
|
|
.Pp
|
|
For all
|
|
drives (including all SCSI-2 drives), the kernel should correctly detect
|
|
the disk geometry.
|
|
.Pp
|
|
If you're installing
|
|
.Nx*M
|
|
for the first time it's a very
|
|
good idea to pre-plan partition sizes for the disks onto which you're
|
|
installing
|
|
.Nx .
|
|
Changing the size of partitions after you've
|
|
installed is difficult. If you do not have a spare bootable disk, it
|
|
may be simpler to re-install
|
|
.Nx
|
|
again from scratch.
|
|
.Pp
|
|
To be able to boot from local disk an
|
|
SGI Volume Header partition is required. This special partition is accessed
|
|
by the PROM to load the
|
|
.Nx*M
|
|
boot program. The partition should be about
|
|
2 MB in size, but can be reduced somewhat. The minimum size can approach
|
|
150k, but this doesn't leave room for upgrade boot programs.
|
|
.
|
|
.Ss2 Install via a bootable CD-ROM
|
|
.
|
|
The
|
|
.Nx*M
|
|
CD-ROM is not ISO-formatted. Since the older SGI PROMs
|
|
do not understand ISO/CD-9660 formats, the CD-ROM image is generated with an
|
|
SGI Volume Header and an FFS-formatted (BSD4.2) partition for the distribution.
|
|
Furthermore, since the filesystem is FFS, the CD cannot be mounted under IRIX.
|
|
.Pp
|
|
To install from a
|
|
.Nx*M
|
|
CD-ROM, follow the procedure above for
|
|
setting the PROM environment for SystemPartition, OSLoadPartition, OSLoader
|
|
and OSLoadFilename. The SCSI and DISK values used should be for your attached
|
|
CD-ROM drive, where
|
|
.Ar X
|
|
is the SCSI-ID of the CD-ROM.
|
|
.
|
|
Using the PROM command-line interface,
|
|
you can boot the CD-ROM installation kernel as follows:
|
|
.Pp
|
|
.(tag 12n -offset indent -compact
|
|
.It Ic ">> boot"
|
|
.tag)
|
|
.Pp
|
|
.Ss2 Installation for diskless configurations
|
|
This sections assumes you know how to configure DHCP, TFTP,
|
|
and NFS services on your server.
|
|
.Pp
|
|
.(enum
|
|
Place the kernel into the TFTP server's download area. If the
|
|
kernel has a
|
|
.Dq .gz
|
|
suffix, you must first uncompress it using the
|
|
.Pa gunzip
|
|
program. You must also decide which kernel you need to boot. Because of
|
|
differences in SGI hardware between different machines, the kernel load
|
|
addresses differ. You will need GENERIC_INDY for the Indy and Indigo2,
|
|
while GENERIC should be enough for the O2.
|
|
.Pp
|
|
.Dl server# Ic cp netbsd-GENERIC /tftpboot/netbsd-sgimips
|
|
.Pp
|
|
Note that your DHCP server must be configured to specify
|
|
this file as the boot file for the client.
|
|
.It
|
|
Unpack the distribution sets into the client's root directory
|
|
on the server.
|
|
.Pp
|
|
.Dl server# Ic cd /export/client/mipseb
|
|
.Dl server# Ic gzcat .../base.tgz | tar xvpf -
|
|
.Dl server# Ic gzcat .../etc.tgz | tar xvpf -
|
|
.Dl [ repeat for all sets you wish to unpack ]
|
|
.It
|
|
Load the kernel from the TFTP server:
|
|
.Pp
|
|
.Dl ">> setenv SystemPartition bootp():"
|
|
.Dl ">> setenv netaddr your.ip.here.please"
|
|
.Dl ">> boot"
|
|
.enum)
|
|
.Pp
|
|
The installation of your diskless
|
|
.Nx*M
|
|
system is now complete! You may now skip ahead to any post-installation
|
|
instructions.
|
|
.Ss2 Once you've booted the diskimage
|
|
.
|
|
Once you've booted the installation kernel you will need to
|
|
select your terminal type. Use
|
|
.Ic iris-ansi
|
|
for an SGI graphics console (Not currently supported)
|
|
.Ic vt100
|
|
for a serial console with a vt100-compatible terminal, or
|
|
.Ic xterm
|
|
or
|
|
.Ic xterms
|
|
for a
|
|
.Xr tip 1
|
|
or
|
|
.Xr cu 1
|
|
connection running in an
|
|
.Xr xterm 1 .
|
|
.Pp
|
|
The system will then start the
|
|
.Ic sysinst
|
|
program.
|
|
.so ../common/sysinst
