Restart the system.  The new PCI board is recognized and configured

automatically.

ISA and PnP Option Boards

ISA boards are not designed with internal registers that define the board

configuration to the system during startup.  Therefore, you must run the

System Configuration Utility (SCU) to define the board to the system.  Run

the SCU before installing an ISA board to reserve system resources for the

board and to prevent conflicts with option boards already installed.  Refer to

“Using the System Configuration Utility” later in this chapter.

PnP boards are ISA boards that contain configuration registers like PCI

boards.  You do not have to run the SCU to define a PnP board.  During

startup, the system BIOS automatically detects the installed board and

assigns the necessary system resources.  Since PnP boards are ISA-based

boards, they can be installed in the same slots as ISA boards.
