Working with adapters
Your computer comes with adapter connectors or slots. The Accelerated Graphics
Port (AGP) video adapter is installed in the AGP slot and some models have a
IEEE 1394 (FireWire) controller adapter installed in the mini-PCI slot. You can install
up to three additional optional adapters in your computer in PCI slots 1 through 3.
See “System-board option connectors” on page 13 for the location of expansion
slots on the system board.
Adapter considerations: The following notes describe the types of adapters that
your computer supports and other information that you must consider when
installing an adapter:
v
Locate the documentation that comes with the adapter and follow those
instructions in addition to the instructions in this chapter. If you need to change
the switch or jumper settings on your adapter, follow the instructions that come
with the adapter.
v Your computer uses a rotational interrupt technique to configure PCI adapters.
Because of this technique, you can install a variety of PCI adapters that currently
do not support sharing of PCI interrupts.
v
You can install only low-profile, 32-bit adapters in PCI slots 1 through 3.
v
Your computer supports 5.0 V signaling and universal PCI adapters; it does not
support 3.3 V signaling adapters.
v PCI slots 1 through 3 are on PCI bus 3.
The computer scans the AGP slot, mini-PCI slot, and PCI expansion slots 1
through 3 to assign system resources. Then, the system starts the PCI devices in
the following order, if you have not changed the default startup sequence: AGP
