Chapter 5 - Upgrading the System 63
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” 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.
