LAN subsystem
Another cost-effective feature for network solutions is the integration of Intel’s 82550 10/100 Mbps Fast Ethernet controller which supports:
•Advanced Configuration and Power Interface (ACPI) 1.0B-based power management
•wake on Magic Packet
•wake on Interesting Packet
•advanced System Management Bus (SMB) based manageability
•Wired for Management (WfM) 2.0 compliance
•IP checksum assist
•PCI 2.2 compliance
•PC 2001 compliance
Expansion slots
AGP bus
AGP is solely developed for the purpose of supporting 3D graphic applications. The AGP Pro (50) slot 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 mainboard 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.
