Software Installation

After formatting and paritioning the disk, you can install the software. The easiest way, IMHO, is to issue a go command to install the default software configuration, then use the step command to step through each subsystem and add or remove non-default modules.

Install default software with go

After the basic filesystems have been created, you must select and install software. I find it easiest to first install the default software with the go option.

Reboot the machine, if it hasn't been already, and at boot up, stop in the Maintenance Menu and select Install Software. This will read information of the CDROM, load up a miniroot, mount some filesystems, then begin the inst program.

Simply type go and all the default system software, man pages, etc will be installed for you. This takes some time. Don't exit yet when it finishes.

Modify the default installation with step

Then tell inst to step through all the modules. It will show you what has been installed (and therefore can be removed), what can be installed from CDROM. I remove things I don't need (eg: FORTRAN), and add things I do need; on Irix-5.3, I added: dps, sysv networking security auditing, avilability monitoring, snmp, accounting, bind, ppp, slip, spell, and bsdlpr. (The most important for me were bind and bsdlpr.) When you've made all your selections, again type go to install the configuration you've chosen.

Afterit's completed use quit, which will do some final post-installation work.

Rebooting now should get you a functioning system. I like to try it out now before installing other software, such as IDO (compiler) and NFS.

Installing other software

Once the system's up and running Irix, I install other software like NFS and IDO from multiuser. Login as root, load the CDROM, and the SGI should show a CDROM icon. Double-click the icon and a GUI installation program will run.

You can choose upgrade or new as appropriate, and it will check disk sizes for you to make sure the software will fit. (NFS is small, IDO is large).

You may have to reboot for the software to take effect (eg: NFS).


Next you'll need to protect the machine's basic accounts and then do basic setup with EZsetup. You should protect the system accounts before you enable networking, or else your system may become a net.victim. :-(
