   * Interact with the boot loader
   * Terms: /boot/grub/menu.lst, grub.cfg and other variations, grub-install, MBR, superblock
-==Notes==
-  * BIOS looks for and runs boot loader from first specified boot device.
-  * Boot loader find and loads specified kernel (with specified kernel options) which loads required modules and starts system processes.
-  * LILO is a 2-stage program
-    * First stage is in 512-byte MBR or in the boot sector of a partition (if it is a secondary boot loader).
-    * Second stage is in /boot/boot.b .
-    * Map file locating kernel is in /boot/map
-    * //lilo// command reads /etc/lilo.conf which contains kernel image locations, kernel options, the default boot disk etc. It encodes this information along with physical disk information and writes it into the boot files (MBR/boot-sector, boot.b and map).
-  * GRUB is a multi-stage boot loader, more flexible than LILO.
-    * Changes take effect immediately.
-    * (hd0,1) -> 2nd partition on the 1st hard disk. Refers only to the order of the disks as seen by the BIOS so order may change if BIOS boot order is changed.
-    * //grub-install// writes to MBR/boot sector. Uses/boot/grub/device.map to map BIOS drives to Linux devices e.g. "(hd0)   /dev/sda".
-    * Grub command-line expects a specific order of commands to boot kernel <code>grub> root (hd0,0)
-grub> kernel /vmlinuz-2.4.18-14 ro root=/dev/hda2
-grub> initrd /initrd-2.4.18-14.img  [optional]
-grub> boot</code>
