Pci Auto Configuration; Ide Auto Configuration; Security Passwords; Lan Subsystem (D850Gbal Only) - Intel D850GB Product Manual

Intel Desktop Board D850GB/D850GBAL Product Guide

PCI Auto Configuration

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

IDE Auto Configuration

If you install an IDE device (such as a hard drive) in your computer, the IDE auto-configuration
utility in the BIOS automatically detects and configures the device for your computer. You do not
need to run the BIOS Setup program after installing an IDE device.

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 <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.
