• Commercial boot loaders - You can load Linux using commercial boot loaders. For example, System
Commander and Partition Magic are able to boot Linux (but still require GRUB to be installed in your
Linux root partition).
Note: Boot loaders such as LOADLIN and System Commander are considered to be third-party boot
loaders and are not supported by Red Hat.
SMP Motherboards and GRUB
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 automatically creates
two boot loader entries.
Note: An SMP kernel is installed by default on Intel® Pentium® 4 systems with hyperthreading.
• The two GRUB entries are Red Hat Enterprise Linux (kernel version) and Red Hat Enterprise Linux
(kernel version-smp). The Red Hat Enterprise Linux (kernel version-smp) boots 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 retain all the functionality as before, but only operate with a single
processor.
