Upgrading Processors

When higher-speed processors become available, you can upgrade the existing processors to faster
processors.
Processors are mounted in a processor retention module that surrounds the processor slots. See
Chapter 2, "Servicing the System," for information on replacing the processors. See Chapter 4,
"System Board," for the location of processor slots and related connectors.
You can upgrade processors by purchasing a processor upgrade kit from Intergraph Computer
Systems. The kit contains the hardware, software, and documentation required for the upgrade.
After installing faster processors, you must reinstall Windows NT on the system to ensure proper
operation with the new processors.

Adding Expansion Cards

You can install Accelerated Graphics Port (AGP), Peripheral Component Interconnect (PCI), non-
compliant PCI, Industry Standard Architecture (ISA), and Plug-n-Play (PnP) expansion cards in
the system. See below for a general description of the types of cards.
PCI cards contain configuration registers that define resource information to the system during
startup. PCI cards do not require manual system configuration when installing the card. 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.
NOTE All PCI expansion cards sold by Intergraph fully comply with the Peripheral
Component Interconnect Specification, 2.1.
Non-compliant PCI cards mechanically comply with the Peripheral Component Interconnect
Specification 2.1, but do not contain configuration registers that allow the system to
automatically assign the necessary resources. These cards install in PCI slots, but you must
configure the BIOS to assign system resources before installing the card. In this regard, they
are like ISA cards, as described below.
Non-PnP ISA cards do not contain registers that define the resource information to the system
during startup. Therefore, you must configure the BIOS to define the card to the system
before installing the ISA card. This reserves system resources for the card.
PnP cards are ISA cards that contain configuration registers like PCI cards. During startup,
the system BIOS automatically detects the installed card and assigns the necessary system
resources. Since a PnP card is ISA-based, you install it in any available ISA slot.
NOTE Assign system resources for any non-PnP ISA card and any non-compliant PCI
cards before installation. See the "Assigning System Resources" section below.
