This page will describe how to install IRIX 6.5 on a clean disc.
You may need to do this when you want to upgrade a pre-6.5 version
to 6.5.x or when you really want to reinstall IRIX or simply got
a new SGI but no operating system on the disc.
Installing IRIX is not that hard, the most complicated step is
setting up the disc, because you have to boot from CD and partition
your drive - this is not that easy, but described in detail here.
We now assume that you have a labeled harddrive ready to receive
a fresh IRIX installation.
What you need
Before you start, make sure that you have at least the following
CDs for IRIX 6.5:
- IRIX 6.5 Foundation 1 & 2
- IRIX 6.5 Installation Tools
Note that the "Installation Tools" are also contained
on the first CD of an IRIX 6.5.x Overlay set. Most often there
is no special CD containing only the installation tools, so don't
worry if you don't have such a disc, but you have overlays. Note
that for an installation from CDs you need bootable overlays -
that is downloading the overlays from www.sgi.com
is not sufficient. You probably want to get your hands on an original
CD set instead.
It is also a good idea to install some applications which can
be found on the following CD:
If you want to install the development system, you also need
- IRIX 6.5 Development Foundation
- IRIX 6.5 Development Libraries
Note that you also need these CDs if you use freeware development
tools like gcc, because these CDs contain all IRIX specific libraries.
You might also want to install
- ONC3/NFS Version 3
- IRIX 6.5 Applications
- IRIX 6.5 Base Documentation
- SCSL Scientific Library
Initializing your Harddisc
First you have to partition and initialize your harddrive before
you can install IRIX onto it. This requires that you first have
to boot the Installation CD either from your local
CD-ROM or from Network.
Please read these two sections for booting into the disc partitioning
We assume that you are using your local CD-ROM
Starting the Installation
When you are ready with preparing you harddisc, you can start
the installer itself. There are two possibilites: Start the installer
from sash by typing install,
or select "Install System Software" from the
main menu of the PROM.
If you get an error message telling you that no swap-space is
available, you first need to initalize
your harddisc via fx.
