Follow this procedure to install an expansion card:
See Chapter 3, "Using the ISA Configuration Utility," for instructions.
NOTE: If you install a PCI or Plug and Play expansion card, your system automati-
cally performs any required configuration tasks during the boot routine.
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.
Save the screw to use when installing the expansion card later in this procedure.
