Feature
Description
Control access to
the BIOS Setup
utility (set supervisor
password)
To control access to the system configuration, set a
supervisor password and enable it through the BIOS
Setup utility. This password allows the supervisor to
make changes to the BIOS Setup utility. The user may
also be allowed to make changes to the BIOS Setup
utility, depending on the user access level setting
(full, limited, view only, or no access).
If both the supervisor and user passwords are
enabled, either can be used to boot the system or
enable the keyboard or mouse, unless Unattended
Start mode is enabled. If Unattended Start mode is
enabled, only the user password may be used to
enable the keyboard and mouse.
Once set, passwords can be disabled by deleting the
password in the BIOS Setup utility, or by changing the
Enable Password jumper. To change the jumper, see
“Setting the system board jumpers” on page 87.
Control access to
the system (set user
password)
To control access to the system, set a user password
and set Password Check to Always, using the BIOS
Setup utility.
Once set, passwords can be disabled by deleting the
password in the BIOS Setup utility, or by changing the
Enable Password jumper. To change the jumper, see
“Setting the system board jumpers” on page 87.
Boot without
keyboard
The system can boot with or without a keyboard. To
enable the system to boot without a keyboard, go the
the boot settings configuration under the Advanced
menu in the BIOS Setup utility and select the System
Keyboard Absent option.
