l Expansion-card connectors PCI1PCI5 support 32-bit PCI expansion cards.
l With the passive riser board option, six expansion-card connectors reside on the riser board. Because one expansion slot is shared, a
maximum of five expansion cards can be installed on the riser board.

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."

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.
