Password on Boot field through Setup or the SSU.

password

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.
