Information Update 3

This document provides updated information for your system

on the following topics:

• System memory update – quad-core processors

• Trusted Platform Module (TPM) update

• System power cable requirements

• System board replacement – safeguarding encrypted data

• LCD status messages update

• System messages update

• PCIe slot update

• System Setup program update

System Memory Update – Quad-Core Processors

On systems with quad-core processors, the 667-MHz memory transfer speed

is supported only if the system contains eight memory modules or fewer

(no more than four modules per processor). On quad-core systems with more

than eight memory modules total, the system BIOS limits the memory

transfer speed to 533 MHz.

See support.dell.com for the latest information on memory support on

quad-core processor systems and for any system updates available for download.

Trusted Platform Module (TPM) Update

Systems shipping in China are not equipped with TPM. Disregard any TPM

options listed in the "Using the System Setup Program" chapter of your

Hardware Owner’s Manual.

System Power Cable Requirements

If you purchased your system without a power cable, you must provide

a power cable approved for use in your country that meets or exceeds

the voltage requirements of your system and is rated for 10A or more.

NOTICE: Do not use a power cable with a current rating of less than 10A.

4Information Update

System Board Replacement – Safeguarding

Encrypted Data

If your system is configured to support the TPM feature, you can use

encryption applications to secure the contents of the hard drive(s).

NOTE: When you use an encryption program, you are prompted to create a

recovery key during system setup. Be sure to store this recovery key. If you replace

the system board, you must supply the recovery key when you restart your system

before you can access the encrypted files on your hard drive(s).

LCD Status Messages Update

The following LCD messages listed in the "LCD Status Messages" table

in the Hardware Owner’s Manual do not apply to your system.

•

E1A15 SAS Cable B

— A SAS cable B is not used on your system.

•

E122F 2.5V PwrGd

— This message applies to a voltage regulator

not present on your system.

System Messages Update

The following system messages are new.

Table 1-1. System Messages Update

Message Causes Corrective Actions

Invalid card found

card slot

An unsupported LAN-

on-motherboard (LOM)

card was detected in

the dedicated LOM

mezzanine card slot.

Replace the invalid card

with a supported LOM

card.

has been entered. User

interaction is required

to proceed.

This is not an error.

Select Ior M to proceed

with the TPM operation.

NOTICE: Modifying can

prevent security. Ensure

that the configuration

change is valid.

Information Update 5

PCIe Slot Update

Following are updates to information provided in the Hardware Owner’s Manual

about the PCIe slots on the riser boards.

• Figure 6-5 incorrectly specifies slot 2 as having a x8 lane width. Although

the physical connector is x8, the actual PCI-e lane width of slot 2 is x4.

• Figure 6-6 specifies slot 3 as having a x8 lane width. This is correct,

however full x8 performance on this slot is application-dependent.

To ensure full x8 performance where needed, use slot 1 or slot 4 for add-in

cards requiring x8 operation.

System Setup Program Updates

CPU Information Screen

If you are running Red Hat®Enterprise Linux®version 5 operating system

on a system containing one or two quad-core AMD®processors, disable

the Demand-Based Power Management option. The system can hang during

shutdown if the option is enabled. This issue will be fixed in a future update

release from Red Hat.

Memory Information Screen

The Low-Power Mode option has been removed from the Memory

Information screen.

Integrated Devices Screen

Microsoft®Windows Server®2008 supports the OS Watchdog Timer option

in the Integrated Devices screen of the System Setup program, but Windows

Server 2003 does not. Windows Server 2003 does not support the WDAT

implementation of the Advanced Configuration and Power Interface (ACPI) 3.0b

specification that is required for the OS Watchdog Timer option.

System Security Screen

TPM is not supported on Microsoft Windows Server 2003. Ensure that the

TPM Security option is disabled on the System Security screen when running

Windows Server 2003 on your system.

6Information Update

Supported Operating Systems Update

If you install the Red Hat Enterprise Linux Server ES version 4.5 (x86-64)

operating system on a system with quad-core processors, you must also apply

the errata kernel 2.6.9550.12 update from Red Hat. See your Red Hat user

documentation for instructions on using the Interactive Red Hat Update

Agent to download and apply the kernel.

Troubleshooting an SD Card or Internal USB Key

The following troubleshooting procedure is an update to the Hardware

Owner’s Manual. For information about the SD card and USB key ports

inside your system and installing or removing these types of memory devices,

see the installation procedures in your Hardware Owner’s Manual.

Problem

• System cannot read data from an SD card or USB key.

Action

CAUTION: Only trained service technicians are authorized to remove the system

cover and access any of the components inside the system. Before you begin this

procedure, review the safety instructions that came with the system.

Enter the System Setup program and ensure that the SD card or USB key

port is enabled. See "Using the System Setup Program" in the

Hardware Owner’s Manual

Turn off the system and attached peripherals, and disconnect

the system from the electrical outlet.

Open the system. See "Opening and Closing the System"

in the

Hardware Owner’s Manual

Reseat the SD card or USB key.

Close the system. See "Opening and Closing the System"

in the

Hardware Owner’s Manual

Reconnect the system to the electrical outlet, and turn on the system

and attached peripherals.

If the problem is not resolved, proceed to the next step.

Repeat step 2 and step 3.

Information Update 7

Insert a different SD card or USB key that you know works properly.

Close the system. See "Opening and Closing the System" in the

Hardware Owner’s Manual

Reconnect the system to the electrical outlet, and turn on the system

and attached peripherals.

If the problem is not resolved, proceed to the next step.

Repeat step 2 and step 3.

Remove the expansion cards from the appropriate expansion-card riser—

riser 1 for an SD card problem or riser 2 for a USB memory key problem.

See "Removing an Expansion Card" in the

Hardware Owner’s Manual

Reseat the expansion-card riser in its socket. See "Expansion-Card Risers"

in the

Hardware Owner’s Manual

Reinstall the expansion cards you removed in step 12.

Close the system. See "Opening and Closing the System" in the

Hardware

Owner’s Manual

Reconnect the system to the electrical outlet, and turn on the system and

attached peripherals.

If the problem is not resolved, see "Getting Help" in the

Hardware Owner’s

Manual

SUSE®Linux Enterprise Server 9 (x86_64) Update

SP3 Update

SATA optical disk drives are not supported by SUSE Linux Enterprise Server

service pack 3 (SP3). The following error messages may appear when

attempting to install the operating system from a SATA optical disk drive:

cannot read media

device not mounted

To resolve this issue, install the operating system from the network or from an

external USB optical drive. Support for SATA optical drives will be provided

in SP4.

8Information Update

SP4 Update

SUSE Linux Enterprise Server SP4 fails to load on systems configured with

quad-core processors and more than 4-GB of RAM. A future maintenance

update from SUSE will correct this issue. Currently, you can bypass the issue

by using one of the following methods:

• In the System Setup program, enable the

Node Interleaving

option on

the

Memory Information

screen.

• In the operating system boot parameter file, set the memory parameter

to a value less than 4-GB (for example, 3900m).

See the operating system documentation if you need more information.

Hyper-V Beta Virtualization Update

Installing Microsoft Windows Vista®or Windows Server 2008 as a guest

operating system on a virtual machine that was created with Hyper-V Beta

virtualization software causes a system crash (blue screen) if the guest

operating system is installed from the system’s internal optical drive. No

other operating systems are affected by this limitation. Until a chipset driver

update to fix the error is provided on support.dell.com, use one of the

following alternate methods for installing the guest operating system

on the virtual machine:

• Use an external USB optical drive attached to the host system.

• Install the operating system using a PXE-based solution,

such as Windows

Deployment Server.
