Operation Manual
Unfortunately, it is often not possible to map the Linux device names to BIOS device
names exactly. It generates this mapping with the help of an algorithm and saves it to
the le device.map, which can be edited if necessary. Information about the le
device.map is available in Section 9.1.2, “The File device.map” (page 162).
A complete GRUB path consists of a device name written in parentheses and the path
to the le in the le system in the specied partition. The path begins with a slash. For
example, the bootable kernel could be specied as follows on a system with a single
PATA (IDE) hard disk containing Linux in its rst partition:
(hd0,0)/boot/vmlinuz
9.1.1.2 An Example Menu File
The following example shows the structure of a GRUB menu le. The example instal-
lation has a Linux boot partition under /dev/sda5, a root partition under /dev/
sda7 and a Windows installation under /dev/sda1.
gfxmenu (hd0,4)/boot/message
color white/blue black/light-gray

The rst block denes the conguration of the splash screen:
The background image message is located in the /boot directory of the /dev/
sda5 partition.
