3.2.1 DIMM Configuration Rules
Sun Ultra 45 or Ultra 25 workstation memory is installed as matched pairs of DDR-1
SDRAM 266-MHz DIMMs. Within a matched pair, DIMMs must be identical. They
must be from the same manufacturer with the same type and number of memory
devices, the same amount of memory per device, and the same memory speed.
■ The Sun Ultra 45 or Ultra 25 workstation requires a minimum of two matching
DIMMs installed in CPU0 (
■ DIMM connectors on the motherboard are color-coded blue and black. Beginning
with CPU0, install DIMMS in pairs, either in the blue or in the black connectors.
■ If you have four DIMMS and two CPUs, install two DIMMs for CPU0 and two for
CPU1 for optimum performance (
When the workstation boots, the OpenBoot PROM checks for compatible memory
modules. See “OpenBoot PROM Memory Message” on page 3-6 for additional
information.
Before replacing Sun Ultra 45 and Ultra 25 memory, verify that the latest versions of

Chapter 3 Replacing the Motherboard and Associated Components 3-15
3.5.4 Installation Considerations for Graphics
Accelerators
PCI-E 2 is the default console display. If there is no graphics accelerator installed
into PCI-E 2, consider the probe order shown in
3.5.4.1 Default Console Display
During the boot sequence, device nodes are probed. The PCI slots are probed in the
order described in
TABLE 3-3 PCI Card Probe Order
Probe
Order Slot Identifier Device Node
1 PCI4 (PCI-E 2) /pci@1f,700000/ device 0
2 PCI2 (PCI-E 0) /pci@1e,600000/pci@0/pci@3/ device 0
3 PCI3 (PCI-E 1) /pci@1e,600000/pci@0/pci@8/ device 0
4 PCI1 (PCI-X 1) /pci@1e,600000/pci@0/pci@9/pci@0,2/ device 1
TABLE 3-3.
TABLE 3-3.
5 PCI0 (PCI-X 0) /pci@1e,600000/pci@0/pci@9/pci@0,2/ device 2
Unless you reconfigure the default, the first graphics accelerator occurring in the
probe order is designated the default console display and assigned the aliases
screen and /dev/fb.
3.5.4.2 Changing the Console Display
You can configure the OpenBoot PROM to designate a different graphics accelerator
as the console display. Use the show-displays utility, the nvalias command, and
the output-device parameter to make this change. For the following example, a
Sun XVR-2500 graphics accelerator is installed in physical slot PCI-E 2 as the default
console display and a Sun XVR-100 graphics accelerator is installed in slot PCI-X 0.
This example configures the Sun XVR-100 graphics accelerator to be the new console
display.
1. Obtain the ok prompt.
See “Obtaining the ok Prompt” on page 10-2.
3-16 Sun Ultra 45 and Ultra 25 Workstations Service and Diagnostics Manual • May 2006
2. Display the device nodes for the installed graphics accelerators.
For example:
ok show-displays
a) /pci@1f,700000/SUNW,XVR-2500@0
b)
/pci@1e,600000/pci@0/pci@9/pci@0,2/SUNW,XVR-100@2
q) NO SELECTION
3. Select the graphics accelerator to be the new console display by typing its
respective letter.
For example:
Enter Selection, q to quit: b
The utility ends and the device node path is loaded into a text buffer.
4. Make an alias for the device node path.
For example:
ok nvalias newconsoledisplay (Ctrl + Y)
Type a space, hold down the Control key, and press the Y key.
5. Configure the output-device parameter for the new console display.
For example:
ok setenv output-device newconsoledisplay
6. Reset the OpenBoot PROM:
ok reset-all
The system now uses the Sun XVR-100 graphics accelerator as the new console
display.
Note – The default console display, the first graphics accelerator found in probe
order, is still aliased to screen. If you want to check the new console display, type:
test newconsoledisplay

12. Select a boot source.
For most component installations you should become superuser and reboot the
workstation so that the Solaris OS finds the new component.
For example:
# reboot -- -r
If you are at the ok prompt, type:
ok boot -r

6.2 Verifying Component Installation
There are several methods for verifying the installation of the new component.
6.2.1 Reconfiguring the System With boot -r Option
1. Boot the system with the -r option, so that the Solaris OS can reconfigure itself
for the new component.
For example:
# boot -- -r
2. Monitor the boot message.
If a warning message is displayed, refer to Section 12.4, “OpenBoot PROM
Messages” on page 12-11.
3. If the problem has not been solved, see “Diagnostics Hierarchy” on page 7-4.
6.2.2 Verifying Configuration With POST
1. Run POST with the diag-switch to true and the diag-level set to max.
2. Verify that the new device is recognized by POST.
Refer to “Power-On Self-Test” on page 11-1.
6.2.3 Verifying Configuration With POST and
OpenBoot Diagnostics
Use OpenBoot Diagnostics to test all devices. Refer to “OpenBoot Diagnostics” on
page 12-6.
