R12000 CPU Upgrade Information
Installing the Software
Make sure you install the software before installing the hardware. You must have
IRIX 6.5 base software installed to be able to install the Overlay IRIX 6.5.x software. For
this upgrade, use the IRIX Overlay CD that shipped with this R12000 CPU hardware.
Note: IRIX 6.5 base software does not ship with the processor upgrade. Contact your
local sales representative to order the base IRIX 6.5.
To check your workstation’s IRIX version, from the Toolchest > Desktop, open a UNIX
shell.
At the prompt, enter

To install the software, follow the instructions in the software installation booklet that
came with your CDs.
