Table 1-8 lists the updated information on the default Failsafe Baud Rate.

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 4Update.
