The five PCI bus slots on the main logic board support bus mastering 32-bit PCI expansion boards for
performance enhancement.
NOTE
One of the PCI slots (P1-1) is in line with a CPU module slot (CPU 2). When installing
a CPU module in this slot, the PCI slot cannot be used.
The PCI bus provides:
♦
32- and 64-bit memory addressing
♦ +
5 V dc and
+
3.3 V dc signaling environments
♦
Burst transfers at 133 MB per second
♦
8-, 16-, or 32-bit data transfers
♦
Plug-and-play configuration
♦
PeerBus to maximize throughput
