System Security 29
Control access to the system
other than SSU: set user
password
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.
Boot without keyboard
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.
Specify the boot sequence
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.
