Installing Irix 6.5.5 on an SGI O2

May apply to other versions of Irix or other types of hardware.

You'll need the following installation cds:
IRIX 6.5.5 Installation Tools and Overlays (1 of 2)	Sequence No 100
IRIX 6.5.5 Overlays (2 of 2)				Sequence No 101
IRIX 6.5 Foundation 1					Sequence No 200
IRIX 6.5 Foundation 2					Sequence No 201
IRIX 6.5 Applications					Sequence No 220
IRIX 6.5 Development Libraries				Sequence No 300

Optional:
Freeware						Sequence No 700

DO NOT CONNECT THE SGI TO THE NETWORK.  SECURE THE MACHINE BEFORE DOING 
SO.  For some tips on how to secure the machine read through my "Securing 
Irix" document.

Start off by turning on the computer.  When the "Stop for Maintenance" 
button appears, click it.  Insert the first cd Sequence No 100.  Next 
click on the Install System Software button.  Select Local CD-ROM, click 
Install, click on Continue.  Next we want to wipe our root harddisk.  Type 
in admin and hit enter.  Then type in mkfs and hit enter.  This will start 
up the Clean Disks Procedure.  If you have your disk backed up (or don't 
care about the data on it) then type y and hit enter.  You'll get a 
warning about all your data will be destroyed.  Type yes and hit enter to 
select the default filesystem.  Once it is done creating the new 
filesystem type return and hit enter.  

Then type from and hit enter.  Then if [/CDROM/dist] appears at the next 
prompt hit enter, if it doesn't then type in  /CDROM/dist  and hit enter.
Select feature stream (2).  Once it is done reading the cd, eject it and 
then insert the next cd (101).  Hit enter.  Once it is done repeat these 
steps for the rest of the required cds.  When you have inserted all the 
required cds, type done and hit enter.  Next type conflicts and hit enter.  
You should see about 7 conflicts.  To resolve these conflicts type  
conflicts 1a 2a 3a 4a 5a 6a 7a  and then hit enter.  The computer should 
say "No conflicts".  Next type go and hit enter.  Insert the various cds 
as it asks for them.  You may come across an error.  Try the retry option.  
If that does not work then try the continue option.  If that does not work 
then use the stop option (you will be on your own from here if you have to 
use the stop option).  Next type quit.  When the installation is done 
restarting type y and hit enter to quit.


Optional:
These steps make Irix more useable to me.  They are not required.
When you computer has restarted, double click on the root icon.  This will 
log you on as the root (no password required).  Next insert the Freeware 
cd and then double click on the CDROM icon.  This will start up the 
Software Manager.  Click on Customize Installation, then click on the 
Selected menu, and then click on Unmark All.  Next check the software 
packages you wish to install.  I like to install:
Perl
bash
bzip2
gzip
less
tar
tcp_wrappers

Next click on the Conflicts button if there are any conflicts.  Conflicts 
may vary, our conflicts were resolved by installing the additional 
packages required (I believe it was the man pages and fw_common.sw.index).  
Then click on start.  When it is done installing, select Exit and click on 
Ok.  I like the way Linux is setup with bash:

edit /etc/bashrc and put in the following lines

#######START######
PS1="[\u@\h \W]\\$ "
PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME%%.*}:${PWD/$HOME/~}\007"'
######END########

Next edit /.bashrc and put in the following lines

#####START#####
# .bashrc

if [ -f /etc/bashrc ]; then
	. /etc/bashrc
fi
######END#######


Next edit /.bash_profile and put in the following lines

#####START######
# .bash_profile
if [ -f ~/.bashrc ]; then
	. ~/.bashrc
fi

PATH=$PATH:/usr/freeware/bin
BASH_ENV=$HOME/.bashrc

export PATH BASH_ENV
#######END#########

You should now be able to type in /usr/freeware/bin/bash and your prompt 
will change from  IRIS 1#  to  [root@IRIS /]#  if it does change correctly 
then edit /etc/passwd and change your shell to /usr/freeware/bin/bash then 
logout and log back in.  Now every new terminal or shell that you open 
should have your new prompt.  Seeing as you now have a new IRIX system 
setup you should read through my Securing IRIX document.
