BIOS Utilities
Security Menu 5 - 11
5
Password on boot: (Security Menu)
Specify whether or not a password should be entered to boot the computer ( you may
only set a password on boot if a supervisor password is enabled ). If “ Enabled ”
is selected, only users who enter a correct password can boot the system ( see the
warning in the sidebar ). The default setting is “ Disabled ”.
Note : To clear existing passwords press Enter and type the existing password, then
press Enter for the new password (without typing any password entry) and Enter
again to confirm the password clearance.
Fixed disk boot sector: (Security Menu)
If you choose “ Write-Protect ” this will protect against viruses being written to the
hard disk boot sector (this is not a substitute for installing an anti-virus program - see
“Viruses” on page 8 - 4 ).
TPM Support (Security Menu)
Enable TPM Support from this menu, and the TPM State menu will then appear
(see “TPM State” on page 5 - 12 ). Note : If you disable TPM Support then your
TPM information may be erased altogether. You should only disable TPM support
when you need to clear the TPM information. The default setting is “
Disabled ”.
Password Warning
If you set a boot pass-
word (Password on boot
is “Enabled“),
NEVER
forget your password.
The consequences of
this could be serious. If
you cannot remember
your boot password you
must contact your ven-
dor and you may lose all
of the information on
your hard disk.
TPM Password
Note that you should set
a supervisor password
in the BIOS to protect
the
TPM information
from being tampered
with by unauthorized us-
ers.
