Information Update 3
This document provides updated information for your system on the following topics:
• Broadcom driver limitation with Red Hat

Linux
• Using DRAC 4/P with Red Hat Enterprise Linux 3 (RHEL 3)
• 64-bit capability
• Microprocessor replacement
Broadcom Driver Limitation With Red Hat Linux
On systems running the Red Hat Linux operating system, if you use the IPMI Pass Through
(IPMI PT) for remote manageability over a LAN and you want to configure VLAN, you must use
the Broadcom Advanced Server Program (BASP) and bcm5700 driver instead of the native Linux
tg3 driver. If you use the native Linux tg3 driver with IPMI PT enabled, the VLAN functionality
will not work correctly. The operating system utilities will let you configure the VLANS, but you
will not receive any traffic over the VLAN interface.
Using DRAC 4/P With Red Hat Enterprise Linux 3
If your system has a DRAC 4/P card installed, the integrated IDE controllers and their devices will
not be available on systems running RHEL 3. As a temporary solution, append the following kernel
parameter to the kernel line for each stanza in the
grub.conf file: ide2=0x1f0 . As an alternative,
go to
rhn.redhat.com and upgrade your kernel to version 2.4.21.15.EL or higher.
64-Bit Capability
If the processor installed in your system has 64-bit capability, the 64-bit Technology option on the
CPU Information screen in the System Setup program will show Yes (Intel
®
EM64T) . If your
system has a 32-bit processor installed, the
64-bit Technology option will show No . This field
specifies if the installed processor supports Intel 64-bit technology.
Microprocessor Replacement
You can upgrade the system processor to take advantage of future options in speed and
functionality.
The processor upgrade kit contains a processor and thermal grease; you will need to re-use
the processor heat sink that came with your system.
