Upgrading the R5000 Class CPU Module to an RM7000 CPU Module

If you are upgrading your R5000 CPU module with a newer CPU, the instructions for installing the processor module are different depending on which version of the operating system you are using.

Note: The RM7000 CPU upgrade requires IRIX 6.5.9 or higher. If your shipment includes an RM7000 CPU upgrade, you must install the IRIX 6.5.9 operating system prior to installing the CPU upgrade.

Follow the installation instructions provided here in the order in which they are given:

  • Install the operating system software, if needed

  • Install the software patches

  • Install the hardware

Before You Begin

Before upgrading your CPU, perform the following step:

Determine your workstation's IRIX operating system version. From the Toolchest, choose Desktop > UNIX Shell. At the prompt, enter:

uname -R

Checking Your Shipment

The following items are included in a CPU upgrade shipment:

  • IRIX 6.3 Recommended/Required Patches 6/99 CD

  • IRIX 6.5.x[1] Overlay CDs

  • Wrist strap

  • Reversible screwdriver

  • R5000 class (RM5271) or RM7000 class CPU processor module

  • Upgrade label

Installing the Upgrade on IRIX 6.3 Systems

Follow the upgrade instructions in this section if your system is running IRIX 6.3.

To upgrade your CPU, verify that you are running correct version of IRIX 6.3 and if not, upgrade to the required version. Then install the IRIX 6.3 Recommended/Required Patches 6/99 CD and install the processor module upgrade.

Procedures for locating and installing relevant documentation begin in “Viewing This Guide From the IRIS InSight Library” in Chapter 1.

Verifying and Installing the Operating System

Install the software before installing the hardware.

For the O2 R5000 class CPU upgrade, you need the version of the IRIX operating system software called “IRIX 6.3 for O2 Including R10000.” Follow the steps below to make sure your system is running the correct version before installing the patches and beginning the hardware upgrade.

  1. Check your workstation's IRIX version. In a shell window, enter:

    uname -R

    • If you see 6.3 O2 R10000, you have the correct IRIX version. Go to “Installing the IRIX 6.3 Recommended/Required Patches 6/99 CD”.

    • If you see 6.3 O2, you must upgrade your workstation to the correct operating system before installing the patches and the hardware. The IRIX 6.3 for O2 Including R10000 CD is included in this shipment. Read the Caution below, and then go to step 2. Otherwise go to “Installing the IRIX 6.3 Recommended/Required Patches 6/99 CD”.

      Caution: Do not install the patch CD that contains the recommended patches now. You do this later, after the IRIX and Applications CDs are installed and you have rebooted the workstation. If you install the patches without rebooting, the flash PROM environment variables may become corrupt. 

  2. Install IRIX 6.3 for O2 Including R10000

    Read any letters or instructions that came with the CD. The CD booklet explains how to read the release notes.

  3. When IRIX 6.3 for O2 Including R10000 has been installed, you must reboot the system before installing the patches CD. From the toolchest, choose Restart System. Log in as usual when you see the Login screen.

You are ready to install the patches.

Note: Now that the system is running the correct version of IRIX, if you ever need to boot from a CD (the miniroot), you must use the “IRIX 6.3 Recommended/Required Patches CD”, not an operating system CD. The new hardware (CPU) is not compatible with the original IRIX 6.3 operating system CD.

Installing the IRIX 6.3 Recommended/Required Patches 6/99 CD

Caution: If you just installed “IRIX 6.3 for O2 Including R10000” and have not rebooted your system, do so before installing the “6.3 Recommended/Required Patches 6/99” CD.

  1. Insert the “6.3 Recommended/Required Patches 6/99” CD in the CD-ROM drive and double-click the CD-ROM drive icon on the desktop. If you have a root password set, you are prompted to enter it.

  2. Read the Installation Startup message that displays and click Dismiss.
