Working with the hardware in the desktop system unit 81
Adding and removing adapter
cards
The desktop 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.
Identifying adapter card connectors
You can install ISA AT or PCI adapter cards. Use the
following table to help you determine what type and
length adapter card you can install in each adapter card
connector. Adapter card connectors are identified in
“Identifying the parts of the system unit” on page 79.

on the system board or to connectors on the CD-ROM
drive. The following table identifies each connector on
the system board and the type of card that might have a
cable you need to connect:
note:
You can install a PCI adapter card in connector
PCI – 1 or an AT adapter card in connector AT – 2.
However, you cannot install adapter cards in
connectors PCI – 1 and AT – 2 at the same time.
You can install a PCI adapter card in connector
PCI – 2 or an AT adapter card in connector AT – 3.
However, you cannot install adapter cards in
