Chapter 3. Installing Red Hat Linux

3.20.4. 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 Linux (kernel version)

and

Red Hat Linux

(kernel version smp)

. The

Red Hat 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 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.

3.21. Network Configuration

If you do not have a network device, you will not see this screen. Skip ahead to Section 3.22.

If you have a network device and you have not already configured your networking (such as booting

from a network boot disk you created and entering in your network information as prompted), you

now have the opportunity (as shown in Figure 3 17) to do so.
