Preparing to install adapter cards

The system unit has seven slots and eight connectors
for adapter cards. A maximum of seven 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 length adapter cards you can install in each adapter
card connector.
Adapter card
Specifications
connector
AT – 1 Can hold a half-length ISA-AT adapter
card.
AT – 2 Can hold a half-length, three-quarter-
length, or full-length ISA-AT adapter card.
PCI – 1 Can hold a half-length or full-length PCI
adapter card.
PCI – 2 Can hold a half-length or full-length PCI
adapter card.
AT – 3 Can hold a half-length, three-quarter-
length, or full-length ISA-AT adapter card.

110 Preparing to install adapter cards
You can install a PCI adapter card in connector
PCI – 2 or an AT adapter card in connector AT – 3.
note:
However, you cannot install adapter cards in con-
nectors PCI – 2 and AT – 3 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 already be 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, make
sure the settings are correct. The documentation that
came with the card contains instructions on changing
system settings. If the documentation refers 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" on page 141.
Before you install an adapter card, use the table on
page 111 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.
