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.
1 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 .
2 Turn off the system and attached peripherals, and disconnect
the system from the electrical outlet.
3 Open the system. See "Opening and Closing the System"
in the
Hardware Owner’s Manual .
4 Reseat the SD card or USB key.
5 Close the system. See "Opening and Closing the System"
in the
Hardware Owner’s Manual .
6 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.
7 Repeat step 2 and step 3.

Information Update 7
8 Insert a different SD card or USB key that you know works properly.
9 Close the system. See "Opening and Closing the System" in the
Hardware Owner’s Manual .
10 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.
11 Repeat step 2 and step 3.
12 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 .
13 Reseat the expansion-card riser in its socket. See "Expansion-Card Risers"
in the
Hardware Owner’s Manual .
14 Reinstall the expansion cards you removed in step 12.
15 Close the system. See "Opening and Closing the System" in the Hardware
Owner’s Manual
.
16 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.
