• User Access Level—This setting specifies the allowed access level
corresponding to the User Password. If Full Access is specified, then
the User Password will permit changing configuration options in the
BIOS Setup Utility. If Limited is specified, then the User Password
will permit access to some configuration options in the BIOS Setup
Utility but not others. If View Only is specified, then the User
Password will permit access to view but not change the configuration
options in the BIOS Setup Utility. This setting will only display if a
Supervisor Password is specified. The default is Full Access.
• Change User Password—This setting specifies a password that must
be entered to access the BIOS Setup Utility or to boot the system. If a
User Password is specified, its access level is restricted according to
the User Access Level configuration option. This setting will only
display if a Supervisor Password is specified. By default, no password
is specified.
• Password Check—This setting specifies when the BIOS should
prompt for a password. If Setup is specified, the BIOS will only
prompt for a password when trying to access the BIOS Setup Utility.
When Always is specified, the BIOS will prompt for a password when
booting the system in addition to accessing the BIOS Setup Utility.
This setting will only display if a Supervisor Password is specified.
The default is Setup.
• Boot Sector Virus Protection—This setting specifies whether or not
the hard disk drive boot sector is write protected. When set to Enabled,
this setting prevents modification of a hard disk boot sector via
INT 13h services, which may help prevent certain computer viruses
from infecting the controller. This setting does not prevent boot sector
modification by 32-bit operating system drivers that access the hard
disk directly. The default is Disabled.
Exiting the BIOS Setup Utility
The Exit setup menu includes all available options for exiting, saving, and
loading the BIOS default configuration. As an alternative to this screen,
press <F9> to load optimal BIOS default settings and <F10> to save
changes and exit setup.
The Exit setup menu includes the following options:
• Save Changes and Exit—Any changes made to BIOS settings are
stored in the battery-backed system CMOS. The setup program then
exits and reboots the controller. The <F10> key can also be used to
select this option.
