20.2.3 The File /etc/grub.conf
The third most important GRUB configuration file after menu.lst and device.map
is /etc/grub.conf. This file contains the commands, parameters, and options the
GRUB shell needs for installing the boot loader correctly:
root (hd0,4)
install /grub/stage1 (hd0,3) /grub/stage2 0x8000 (hd0,4)/grub/menu.lst
quit
Meaning of the individual entries:
root (hd0,4)
This command tells GRUB to apply the following commands to the first logical
partition of the first hard disk (the location of the boot files).
install parameter
The command grub should be run with the parameter install. stage1 of the
boot loader should be installed in the the extended partition container
(/grub/stage1 (hd0,3)). This is a slightly esoteric configuration, but it is
known to work in many cases. stage2 should be loaded to the memory address
0x8000 (/grub/stage2 0x8000). The last entry
((hd0,4)/grub/menu.lst) tells GRUB where to look for the menu file.
20.2.4 Setting a Boot Password
Even before the operating system is booted, GRUB enables access to file systems. Users
without root permissions can access files in your Linux system to which they have no
access once the system is booted. To block this kind of access or prevent users from
booting certain operating systems, set a boot password.
IMPORTANT: Boot Password and Splash Screen
If you use a boot password for GRUB, the usual splash screen is not displayed.
