6.23 Inactivity Timer 
If the inactivity timer function is enabled, and no keyboard or mouse actions have occurred for 
the specified time-out period, the following occurs until the user password is entered:  
• 
PS/2 keyboard and PS/2 mouse input is disabled. PS/2 keyboard lights start blinking. 
• 
On-board video is blanked (if selected in setup) 
• 
Floppy drive is write protected (if selected in setup) 
• 
Front panel reset, sleep (if present) and power switches are locked 
If a user password is entered, a time-out period must be specified in setup.  
6.24  Hot Key Activation 
Rather than having to wait for the inactivity time-out to expire, a hot-key combination allows the 
user to activate secure mode immediately. The hot-key combination is configured through 
Setup. The following keys are valid hot keys: Ctrl-Alt <L, Z>. Setup will not permit the user to 
choose any other key as the hot key. Note that the hotkey will only work on PS/2 keyboards. 
Hotkey will also only work locally, it will not work from a remote session over redirection. 
6.25  Password Clear Jumper 
If the user or administrator password(s) is lost or forgotten, both passwords may be cleared by 
moving the password clear jumper on the base board, into the “clear” position. The BIOS 
determines if the password clear jumper is in the “clear” position during BIOS POST and clears 
any passwords if required. The password clear jumper must be restored to its original position 
before a new password(s) can be set.  
6.26  Secure Mode (Unattended start) 
Secure mode refers to a system state where many of the external inputs and outputs are 
disabled to prevent tampering. These include PS/2 ports, floppy and on-board video. 
6.27  Front Panel Lock 
The front panel buttons, including power and reset, are always disabled when the system is in 
secure mode. If the system has a sleep switch, it will also be disabled while the system is in 
secure mode. 
6.28 Video Blanking 
If enabled in Setup, and a monitor is attached to the embedded VGA controller, the video will be 
blanked upon entering secure mode. This feature prevents unauthorized users from viewing the 
screen while system is in secure mode. Video monitors attached to add-in video adapters will 
not be blanked regardless of the setting of the video blanking feature.
