Working with adapters
Your computer has three PCI adapter connectors or slots and one AGP adapter
slot. The AGP video adapter is installed in the AGP slot. All PCI slots are 32-bit, 33
MHz slots.
See "System board" on page 23 for the location of the expansion slots on the
system board.
Adapter considerations: Before you install adapters, review the following:
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
switch or jumper settings on your adapter, follow the instructions that come with
the adapter.
v You can install low-profile adapters in all three PCI slots.
v Your computer supports 5.0 V and universal PCI adapters; it does not support
3.3 V adapters.
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 PCI interrupt sharing.
v PCI slots 1 through 3 are on PCI bus 0.
The system scans the AGP slot and PCI expansion slots 1 through 3 to assign
system resources; then the system starts the PCI devices in the following order:
PCI expansion slots 1 and 2, system board integrated drive electronics (IDE) or
SCSI devices, and then PCI expansion slot 3.
