Introduction
1
8
Expansion Slots
The system board is equipped with 1 AGP slot, 5 PCI slots (1
shared with CNR slot) and 1 CNR slot.
The AGP slot only supports 1.5V AGP 4x (1066MB/sec. bandwidth)
add-in cards. AGP is an interface designed to suppor t high
performance 3D graphics cards for 3D graphics applications. It
handles large amounts of graphics data with the following features:
• Pipelined memory read and write operations that hide memor y
access latency.
• Demultiplexing of address and data on the bus for nearly 100
percent efficiency.
CNR (Communication and Networking Riser) is an interface that
supports multi-channel audio, V.90 analog modem, phone-line based
networking or 10/100 Ethernet based networking riser board.
