boot processes is needed when booting from a CD-ROM because
linux does not really know how to do it. When booting from a CD-
ROM an initrd (initial ramdisk) is used as the root filesystem.
This initrd is loaded by the *boot loader*, not the kernel,
making it possible to boot from any device the bootloader can
access. ISOLINUX is the boot loader commonly used for booting
from a CD-ROM.  Linux boot process from hard drive:  1. PC
initializion phase - BIOS, POST. 1. PC starts boot loader -
usually grub or lilo. 1. The bootloader locates kernel image on
the hard drive. 1. The kernel decompresses and loads itself.
Once finished it tries to mount the root filesystem. 1. When the
root filesystem is mounted, /sbin/init is executed and continues
booting the system using inittab and /etc/rc*.d scripts  Linux
