separated list.
The following is an example kernel command:
kernel /vmlinuz-2.6.8-1.523 ro root=/dev/VolGroup00/LogVol00
The option in the previous example specifies that the root file system for Linux is located on
the hda5 partition.
• root (,) — Configures the root partition for
GRUB, such as (hd0,0), and mounts the partition.
The following is an example root command:
root (hd0,0)
• rootnoverify (,) — Configures the root
partition for GRUB, just like the root command, but does not mount the partition.
Other commands are also available; type help --all for a full list of commands. For a
description of all GRUB commands, refer to the documentation available online at
http://www.gnu.org/software/grub/manual/.
7. GRUB Menu Configuration File
The configuration file (/boot/grub/grub.conf), which is used to create the list of operating
systems to boot in GRUB's menu interface, essentially allows the user to select a pre-set group
of commands to execute. The commands given in Section 6, “GRUB Commands” can be used,
as well as some special commands that are only available in the configuration file.
7.1. Configuration File Structure
The GRUB menu interface configuration file is /boot/grub/grub.conf. The commands to set
the global preferences for the menu interface are placed at the top of the file, followed by
stanzas for each operating kernel or operating system listed in the menu.
The following is a very basic GRUB menu configuration file designed to boot either Red Hat
Enterprise Linux or Microsoft Windows 2000:
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
