Intel Desktop Board D946GZTS Product Guide PCI and PCI Express* Auto Configuration If you install a PCI/PCI Express add-in card in your computer, the PCI/PCI Express auto-configuration utility in the BIOS automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that add-in card. You do not need to run the BIOS Setup program after you install a PCI/PCI Express add-in card. 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 BIOS 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. Related Links: For instructions on resetting the password, see Clearing Passwords on page 53. Hardware Management Features The hardware management features of Desktop Board D946GZTS enable the board to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features including the following: • Fan speed monitoring and control • Thermal and voltage monitoring • Chassis intrusion detection Hardware Monitoring and Fan Speed Control The features of the hardware monitoring and fan speed control include: • Monitoring of power supply voltages to detect levels above and below acceptable values • Intel Precision Cooling Technology • Thermal sensors in the processor, GMCH, and ICH7 plus an onboard remote sensor • Thermally monitored closed-loop fan control, for all onboard fans, that can adjust fan speed or switch the fans off as needed 18

PCI and PCI Express
*
Auto Configuration
If you install a PCI/PCI Express add-in card in your computer, the PCI/PCI Express
auto-configuration utility in the BIOS automatically detects and configures the
resources (IRQs, DMA channels, and I/O space) for that add-in card.
You do not need
to run the BIOS Setup program after you install a PCI/PCI Express add-in card.
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 BIOS 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 <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.

For instructions on resetting the password, see Clearing Passwords on page 53.
Hardware Management Features
The hardware management features of Desktop Board D946GZTS enable the board to
be compatible with the Wired for Management (WfM) specification.
The board has
several hardware management features including the following:
Fan speed monitoring and control
Thermal and voltage monitoring
Chassis intrusion detection
Hardware Monitoring and Fan Speed Control
The features of the hardware monitoring and fan speed control include:
Monitoring of power supply voltages to detect levels above and below acceptable
values
Intel Precision Cooling Technology
Thermal sensors in the processor, GMCH, and ICH7 plus an onboard remote sensor
Thermally monitored closed-loop fan control, for all onboard fans, that can adjust
fan speed or switch the fans off as needed
