8.1.3 The File /etc/grub.conf
The third 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:
setup --stage2=/boot/grub/stage2 --force-lba (hd0,1) (hd0,1)
quit
This command tells GRUB to automatically install the boot loader to the second partition
on the first hard disk (hd0,1) using the boot images located on the same partition. The
--stage2=/boot/grub/stage2 parameter is needed to install the stage2 image
from a mounted file system. Some BIOSes have a faulty LBA support implementation,
--force-lba provides a solution to ignore them.
8.1.4 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 to 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.
As the user root, proceed as follows to set a boot password:
1 At the root prompt, encrypt the password using grub-md5-crypt:
2 Paste the encrypted string into the global section of the file menu.lst:
