D-Link DFE-530TX PCI Fast Ethernet Adapter (rev.C):The DFE-530TX uses the bus master burst mode to directly transfer network data between the card and the hostÃ???Ã??Ã?Â´s memory, bypassing the hostÃ???Ã??Ã?Â´s CPU to offload the hostÃ???Ã??Ã?Â´s work load. This PCI adapter removes network bottlenecks and is ideal for high-power servers and videographic or multimedia stations.
