Booting and Boot Managers
4. To keep users from booting certain operating systems, add the entry
lock for every section in menu.lst to prevent booting without en-
tering a password. Example:
title linux
kernel (hd0,4)/vmlinuz root=/dev/hda7 vga=791
initrd (hd0,4)/initrd
lock
After rebooting, trying to boot this entry from the menu would result
in the following error message:
Error 32: Must be authenticated
Return to the menu by pressing




Enter . From the menu, pressing




P
prompts for the password. The selected system (Linux in this case)
should boot after typing the password and pressing




Enter .
Note
Boot Password and Splash Screen
Setting a boot password for GRUB disables the graphical splash
screen as displayed by default.

8.4.6 Boot Problems with GRUB
The geometry of attached hard disks is checked by GRUB only upon boot-
ing. In some cases, the BIOS returns inconsistent values and GRUB reports
GRUB Geom Error (see http://portal.suse.com/sdb/en/2003/03/
fhassel_geom-error.html). In this case, use LILO or update the BIOS.
Details about the installation, configuration, and maintenance of LILO is
available in the Support Database article: http://portal.suse.de/
sdb/en/2004/01/lilo_overview.html.
8.4.7 For More Information
Extensive information about GRUB is available at http://www.gnu.
org/software/grub/. If you have texinfo installed on your machine,
view the GRUB info pages in a shell by entering info grub. You can
also search for the keyword “GRUB” in the Support Database at http:
//portal.suse.de/sdb/en/index.html to get information about
special issues.
