Table 4: Software Security Features (Continued)
Feature
Control access to the system
other than SSU: set user
password
Boot without keyboard
Specify the boot sequence
Description
To control access to the system, set a user password and enable the
Password on Boot field through Setup or the SSU.
Once set, passwords can be disabled by setting the password to a null
string or by changing the Clear Password jumper. See "Security Add-in"
on page 116 to set the password to a null string; or, to change the
jumper, see "Password Clear Jumper" on page 75.
The system can boot with or without a keyboard. During POST and
before the system boots, BIOS automatically detects and tests the
keyboard, if present, and displays a message. No entry exists in the SSU
for enabling or disabling a keyboard. Do not plug in a keyboard while
power is applied to the system.
The sequence you specify in the BIOS (see "Boot Device Priority
Submenu" on page 96) or the SSU (see "Multiboot Options Add-in" on
page 115) determines the boot order. If secure mode is enabled (user
password is set), you are prompted for a password before the system
boots fully. If secure mode is enabled and the Secure Mode Boot option
is also enabled, the system boots fully but requires a password before
accepting any keyboard or mouse input.
