Chapter 4. Installing Red Hat Enterprise Linux

4.18.4. SMP Motherboards, GRUB, and LILO

This section is specific to SMP motherboards only. SMP, short for Symmetric Multiprocessing, is a

computer architecture providing fast performance by making multiple CPUs available to complete

individual processes simultaneously (multiprocessing).
If the installation program detects an SMP motherboard on your system, it will automatically create

two boot loader entries.

Note

Intel® Pentium® 4 systems with hyperthreading will have an SMP kernel installed by default.

The two GRUB entries will be

Red Hat Enterprise Linux (

kernel version

)

and

Red Hat

Enterprise Linux (

kernel version

-smp)

. The

Red Hat Enterprise Linux (

kernel

version

-smp)

will boot by default. However, if you have trouble with the SMP kernel, you can

elect to boot the

Red Hat Enterprise Linux (

kernel version

)

entry instead. You will

retain all the functionality as before, but you will only be operating with a single processor.
The two LILO entries will be

linux

and

linux-up

. The

linux

entry will boot by default. However,

if you have trouble with the SMP kernel, you can elect to boot the

linux-up

entry instead. You will

retain all the functionality as before, but you will only be operating with a single processor.

4.19. Network Configuration

If you do not have a network device this screen is not shown. Skip ahead to Section 4.20

Firewall

Configuration

Figure 4-17. Network Configuration

The installation program automatically detects any network devices you have and display them in the
