6 Property and data protection
The lockable rack door protects the server against unauthorized access.
You can protect your system and your data internally against unauthorized
access using the BIOS Setup security functions (see also the section “BIOS
Setup” on page 47):
– Set the administrator and user passwords.
– Set secure mode to prevent keyboard or mouse input and prevent use of the
operating controls.
Password protection
BIOS passwords prevent tampering with the server. If you set the user
password but not the administration password, BIOS ask you to enter the user
password before you can boot the server. If, however, you set both passwords,
you can start the server or enable the keyboard and mouse once you have
entered either password. You can only change the server configuration with
BIOS Setup if you have entered the administration password.
Secure boot mode
Secure boot mode allows you to boot the server and run the operating system.
However, you cannot use the keyboard or the mouse until you enter the user
password.
You can use BIOS Setup to put the server in secure boot mode. If BIOS detects
a CD-ROM in the CD-ROM drive or a floppy disk in drive A, you are prompted
to enter a password. Once you have entered the password, the server is booted
from the CD-ROM in the CD-ROM drive or the floppy disk in drive A. Entering a
password also disables secure mode.
If there is no CD-ROM or floppy disk in one of the drives, the server boots from
drive C and automatically goes into secure mode. All enabled secure mode
settings go into effect when the server is booted. If you set a hot-key combi-
nation, you can secure the server immediately.
