Overview of BIOS Features
Notes on using USB legacy support:
xIf USB legacy support is enabled, don't mix USB and PS/2 keyboards and mice. For example,
do not use a PS/2 keyboard with a USB mouse, or a USB keyboard and a PS/2 mouse.
xDo not use USB devices with an operating system that does not support USB. USB legacy is
not intended to support the use of USB devices in a non USB operating system.
xUSB legacy support is for keyboards and mice only. Hubs and other USB devices are not
supported.
3.14 BIOS Setup Program Access
The BIOS security features restrict who can access the BIOS Setup program and boot the
computer. A administrator password and a user password can be set for the Setup program and for
booting the computer, with the following restrictions:
xThe administrator password gives unrestricted access to view and change all the Setup options
in the Setup program. This is administrator mode.
xThe user password gives restricted access to view and change Setup options in the Setup
program. This is user mode.
xIf only the administrator password is set, pressing the <Enter> key at the password prompt of
the Setup program allows the user restricted access to Setup.
xIf both the administrator and user passwords are set, users can enter either the administrator
password or the user password to access Setup. Users have access to Setup respective to
which password is entered.
xSetting the user password restricts who can boot the computer. The password prompt will be
displayed before the computer is booted. If only the administrator password is set, the
computer boots without asking for a password. If both passwords are set, the user can enter
either password to boot the computer.
3.15 Recovering BIOS Data
Some types of failure can destroy the BIOS. For example, the data can be lost if a power outage
occurs while the BIOS is being updated in flash memory. The BIOS can be recovered from a
diskette using the BIOS recovery mode (see Section 1.15).
To create a BIOS recovery diskette, a bootable diskette must be created and the recovery files
copied to it. The recovery files are available from Intel, contact Intel customer support for further
information. See Section 6.1 for information on contacting Intel customer support.
