Preparing to install adapter cards

The system unit has three slots and five connectors for
adapter cards. A maximum of three adapter cards can
be installed in the system unit at one time. You can
install ISA-AT or PCI adapter cards.

Adapter card specifications

Use the following table to help you determine what type
and size of adapter card to install in each adapter card
connector.

can install an adapter card in connector 3a or 3b, but
you cannot have adapter cards installed in connectors
3a and 3b at the same time.

Adapter card settings

When you install an adapter card, you may have to set
switches or move jumpers to make the card work
properly with any cards that may be already installed. If
you install a Plug and Play adapter card, however, you
typically do not have to change any switch or jumper
settings after you install it. The computer and the card
automatically work together to make sure the settings
are correct.
If you install non–Plug and Play adapter cards, you must
make sure the settings are correct. The documentation
that came with the card contains instructions on
changing system settings. If the documentation refers
you to information about your computer's I/O addresses,
system board interrupt requests (IRQs), or DMA channel
assignments, you can find this information in "Appendix
A" on page 107.
Before installing an adapter card, see Table 10 on
page 83 to determine whether you need to change any
settings.
If your computer came with any preinstalled adapter
note:
cards, they are non–Plug and Play adapter cards.
