Desktop Board Features Security Passwords The BIOS includes security features that restrict whether the BIOS Setup program can be accessed and who can boot the computer. A supervisor password and a user password can be set for the Setup and for booting the computer, with the following restrictions: • • The supervisor password gives unrestricted access to view and change all Setup options. If only the supervisor password is set, pressing at the password prompt of Setup gives the user restricted access to Setup. If both the supervisor and user passwords are set, you must enter either the supervisor password or the user password to access Setup. Setup options are then available for viewing and changing depending on whether the supervisor or user password was entered. Setting a user password restricts who can boot the computer. The password prompt is displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, you can enter either password to boot the computer. • Speaker A 47 Ω inductive speaker is mounted on the desktop boards.

The supervisor password gives unrestricted access to view and change all Setup options.
If
only the supervisor password is set, pressing <Enter> at the password prompt of Setup gives
the user restricted access to Setup.
•
If both the supervisor and user passwords are set, you must enter either the supervisor
password or the user password to access Setup.
Setup options are then available for viewing
and changing depending on whether the supervisor or user password was entered.
•
Setting a user password restricts who can boot the computer.
The password prompt is
displayed before the computer is booted.
If only the supervisor password is set, the computer
boots without asking for a password.
If both passwords are set, you can enter either password
to boot the computer.
Speaker
A 47
Ω
inductive speaker is mounted on the desktop boards.
The speaker provides audible error
code (beep code) information during the Power-On Self-Test (POST).
LAN Subsystem (Optional)
The Intel 82562ET (in conjunction with the Intel 82801BA ICH2) provides a Fast Ethernet Wired
for Management (WfM) PCI LAN subsystem providing both 10Base-T and 100Base-TX
connectivity.
Features include:
•
32-bit, 33-MHz direct bus mastering on the PCI bus
•
Shared memory structure in the host memory that copies data directly to/from host memory
•
10Base-T and 100Base-TX capability using a single RJ-45 connector with connection and
activity status LEDs
•
IEEE 802.3u Auto-Negotiation for the fastest available connection
•
Jumperless configuration; the LAN subsystem is completely software configurable
