Expansion Slots
Nine expansion-card connectors reside on the riser board (see Figure 3 ). Because two expansion slots are shared, a maximum of seven
expansion cards can be installed on the riser board.
l Expansion-card connectors ISA1 –ISA4 support 8- or 16-bit ISA expansion cards.
l
Expansion-card connectors PCI1 –PCI5 support 32-bit PCI expansion cards.

Installing an Expansion Card
Follow this procedure to install an expansion card:
1. If you are installing a non-Plug and Play ISA expansion card, enter the ISA Configuration Utility (ICU) and add the new
expansion card to your configuration.
See " Using the ISA Configuration Utility " for instructions.
2. Prepare the expansion card for installation, and remove the computer cover according to the instructions in " Removing the
Computer Cover ."
See the documentation that came with the expansion card for information on configuring the card, making internal connections, or otherwise
customizing the card for your system.
3. Remove the expansion-card cage as instructed in " Removing the Expansion-Card Cage ."
4. Unscrew and remove the metal filler bracket that covers the card-slot opening for the expansion slot you intend to use (see
Figure 4).
Save the screw to use when installing the expansion card later in this procedure.
Figure 4. Removing the Filler Bracket
NOTE: On shared expansion slots, only one card of either type can be installed in the common slot.
CAUTION: To avoid the possibility of electric shock, turn off the computer and any peripherals, disconnect them from their
electrical outlets, and then wait at least 5 seconds before you remove the computer cover. Also, before you install an
expansion card, see "
Safety First — For You and Your Computer ."
NOTE: If you install a PCI or Plug and Play expansion card, your system automatically performs any required configuration tasks
during the boot routine.
CAUTION: Some network cards automatically start up the system when they are connected. To guard against electrical shock,
be sure to unplug your computer from its electrical outlet before you install any expansion cards.
