AGP Bus (2X/4X)
AGP is developed solely for the purpose of supporting 3D graphic applications. It has a
32-bit wide channel that runs at 66 MHz, which translates into a total bandwidth of 266
MBps. This is twice the bandwidth of PCI buses (133 MBps). AGP also accesses the main
memory directly, allowing 3D textures to be stored in main memory rather than video
memory.
PCI Bus
The system board has five PCI buses that support 32-bit/33 MHz PCI devices. The PCI
bus is the key interface that communicates between the north and the south bridge.
Hardware Management Support
The system board supports the power-management function that conforms to the
power-saving standards of the U.S. Environmental Protection Agency (EPA) Energy Star
program. It also offers the Plug-and-Play feature. This feature saves the user from
configuration troubles, thus making the system more user-friendly.
