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.
