Chapter 5 - Upgrading the System 61
Adding Option Boards
This section briefly describes the differences between Peripheral Component
Interconnect (PCI), Industry Standard Architecture (ISA), and Plug-n-Play
(PnP) option boards. Instructions are also provided for installing option
boards into a deskside 3D Graphics Workstation.
Option boards are installed on the riser card. PCI boards connect to side one
of the riser card, while ISA and PnP boards can be installed on both sides.
Only one ISA or PnP board can be installed on side one, if a PCI board is not
installed in the bottom PCI slot. The following figure shows the slots on the
riser card.
PCI Boards
PCI boards do not require manual system configuration when installing the
board. The system BIOS detects the board’s presence during startup and
reads information from the board’s configuration registers to assign the
necessary system resources.
