Preparing to install adapter cards

The system unit has four slots and connectors for
adapter cards. You can install ISA-AT 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. You can install an adapter card in any empty
slot/connector in which the card fits.

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 115.
Before installing an adapter card, see Table 10 on
page 85 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.
