Chapter 2. Boot Loaders
Before Red Hat Linux can run, it must be loaded into memory by a special program
called a boot loader. A boot loader usually exists
on the system's primary hard drive (or other media device) and has the sole

some cases) other operating systems into memory.
2.1. Boot Loaders and System Architecture
Each architecture capable of running Red Hat Linux uses a different boot
loader. For example, the Alpha architecture uses the
aboot boot loader, while the Itanium architecture
uses the ELILO boot loader.
This chapter discusses commands and configuration options for the two
boot loaders supplied with Red Hat Linux for the x86 architecture: GRUB and
