• splashimage — Specifies the location of the splash screen image to be used when GRUB boots.
• title — Sets a title to be used with a particular group of commands used to load an operating
system.
The # character can be used to place comments in the menu configuration file.
5.5.2 Configuration File Structure
The commands to set the global preferences for the GRUB menu interface are placed at the top of the
file, followed by the different entries for each of the operating systems to boot.
A very basic GRUB menu configuration file designed to boot either Red Hat Linux or Microsoft Win-
dows 2000 might look like this:
default linux
timeout 10
color green/black light-gray/blue
# section to load linux
title linux
root (hd0,1)
kernel /vmlinuz root=/dev/hda5
boot
# section to load Window 2000
title windows
rootnoverify (hd0,0)
chainloader +1
This file would tell GRUB to build a menu with Red Hat Linux as the default operating system, set
to autoboot it after 10 seconds. Two sections are given, one for each operating system entry, with
commands specific to this system's partition table.
Actually configuring a GRUB menu configuration file to boot multiple operating systems is beyond
the scope of this chapter. Please consult Section 5.6, Additional Resources for the detailed information
required to boot the various operating systems possible with GRUB.
