Operating System Information Enumeration of NICs Linux operating system versions that use the udev kernel device manager enumerate the NICs differently than earlier Linux versions that used the devfs device manager. Although this does not affect system functionality, when using Red Hat® Enterprise Linux® (version 4 or version 5) or SUSE® Linux Enterprise Server 9 or 10 operating systems, the NICs are enumerated in reverse: NIC1 is configured as eth1 instead of eth0, and NIC2 is configured as eth0 instead of eth1. For information on how to change the default device enumerations, see the "Network Interface Card Naming" white paper available at linux.dell.com. RHEL - Incorrect Processor Information • If an Intel Xeon 54xx processor is installed in a system running RHEL Version 4 Update 5 and Demand-Based Switching is enabled in the BIOS, cat/proc/cpuinfo and cat/sys/devices/system/cpu/cpuxx/cpufreq/scaling_ cur_freq displays an incorrect processor frequency. (The actual processor speed is not affected.) • If an Intel Xeon 54xx processor is installed in a system running RHEL Version 3 Update 9, incorrect processor information is displayed in /proc/cpuinfo. (The actual processor speed is not affected.) This behavior will be corrected in a future RHEL 4 Update. System Support for Microsoft Windows 2000 If you run the System Build and Update Utility, Microsoft® Windows® 2000 is included in the list of operating systems on the Server OS Install tab. This operating system is supported by the PowerEdge 1950 and 1950 II systems, but not by the PowerEdge 1950 III system. Information Update 25

Operating System Information
Enumeration of NICs
Linux operating system versions that use the
udev
kernel device manager
enumerate the NICs differently than earlier Linux versions that used the
devfs
device manager. Although this does not affect system functionality,
when using Red Hat
®
Enterprise Linux
®
(version 4 or version 5) or SUSE
®
Linux Enterprise Server 9 or 10 operating systems, the NICs are enumerated
in reverse: NIC1 is configured as
eth1
instead of
eth0
, and NIC2 is configured
as
eth0
instead of
eth1
. For information on how to change the default device
enumerations, see the "Network Interface Card Naming" white paper
available at
linux.dell.com
.
RHEL – Incorrect Processor Information
•
If an Intel Xeon 54xx processor is installed in a system running RHEL
Version 4 Update 5 and Demand-Based Switching is enabled in the BIOS,
cat/proc/cpuinfo
and
cat/sys/devices/system/cpu/cpuxx/cpufreq/scaling_
cur_freq
displays an incorrect processor frequency. (The actual
processor speed is not affected.)
•
If an Intel Xeon 54
xx
processor is installed in a system running RHEL
Version 3 Update 9, incorrect processor information is displayed in
/proc/cpuinfo
. (The actual processor speed is not affected.)
This behavior will be corrected in a future RHEL 4 Update.
System Support for Microsoft Windows 2000
If you run the
System Build and Update Utility
, Microsoft
®
Windows
®
2000
is included in the list of operating systems on the
Server OS Install
tab.
This operating system is supported by the PowerEdge 1950 and 1950 II
systems, but not by the PowerEdge 1950 III system.
