Motherboard BIOS and Setup Utility

✏NOTE
IRQ 3, 4, 5, and 7 may not be available in this option, depending on the setting chosen for the
COM1, COM2 and parallel ports in the Peripheral Configuration Subscreen.
IRQ 14 and 15 will not show up as user available. If the on-board IDE controller is not used,
these interrupts will be available to ISA cards. These interrupts can not be used for PCI cards.
3.12.11 Security Screen
This section describes the two access modes that can be set using the options found on the Security
screen, and then describes the Security screen options themselves.
3.12.11.1 Administrative and User Access Modes
The options on the Security screen menu make it possible to restrict access to the Setup program
by enabling you to set passwords for two different access modes: Administrative mode and User
mode.
In general, Administrative mode has full access to the Setup options, whereas User mode has
restricted access to the options. Thus, by setting separate Administrative and User passwords, a
system administrator can limit who can change critical Setup values. The actual limitations depend
on whether either the Administrative or User passwords or both are set. (See the table below for a
description of how the passwords actually work together.)
To limit access to who can boot the system, set the User password. This is the password that the
system asks for before booting. If only the Administrative password is set, the system boots up
without asking for a password. If both passwords are set, you can enter either password to boot the
system.
The following table shows the effects of setting the Administrative and User passwords. (The table
is for reference only, and is not shown on the Security screen.) In the table, the statement “Can
change a limited number of options” means you can change the system date and time, the power
management hot key, the User password, the security hot key, and unattended start.
