NOTE
Since the second processor should be the same speed as the first, you do not have to change
any processor frequency jumper settings when installing a second processor.
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.
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 the ISA slot.
NOTE
Assign system resources for an ISA card and any non-compliant PCI cards before installation.
See the “Assigning System Resources” section below.
Each installed PCI card must draw less than 25 watts of power. The total allowable maximum
wattage for PCI cards is 175 watts. The PCI slots are limited to 25 watts power dissipation
per the Peripheral Component Interconnect Specification 2.1.
Slot Locations
The expansion slots are located at the bottom, left section of the system board, as shown in the
following figure. PCI slots 1 through 3 are on a primary PCI bus connected to the primary LE
chipset. PCI slots 4 through 7 are on a primary PCI bus connected to the secondary LE
chipset. Slot 7 is a shared PCI/ISA slot. You can install a card in the number 7 PCI slot or
the ISA slot, but not both.
