If the switch does not support auto-negotiation, the (single capability) message will be recognized by the DFE-538TX auto-negotiation facility, which will switch to those settings of its own capabilities, which match that of the switch. Auto-negotiation reoccurs any time the linkage is restored, making the line ready again for optimal data communications. About PCI Bus Your DFE-538TX Adapter delivers outstanding performance by fully exploiting the advance features of your computer's PCI bus. DFE-538TX Adapters utilize the Bus Master Mode of the PCI bus, allowing direct transfers of Ethernet packet content between computer memory and the adapter's controller, thus minimizing network demands on the CPU. The adapter's controller function provides the additional benefit of reduced command processing overhead. The working relationship between a DFE-538TX adapter and main memory working in Bus Master mode is powered by the Bridge/Memory Controller of the PCI bus. This reduces the CPU role in network operations, thus freeing the CPU to service other tasks, with resulting improvement in overall computing (multitasking) performance. At the same time, it produces superior network throughput by reducing latency (waiting for CPU service) during transmissions and receptions. Features Wake On LAN Wake On LAN (WOL) is an ACPI function allowing a powered down (sleeping) computer to be powered ON from a remote station. To use the WOL feature, the NIC must be WOL capable and the motherboard of the PC must be ACPI compliant. While powered-down computers Sleep, WOL enabled NICs monitor LAN traffic 5

Wake On LAN (WOL) is an ACPI function allowing a powered down (sleeping)
computer to be powered ON from a remote station. To use the WOL feature, the
NIC must be WOL capable and the motherboard of the PC must be ACPI compliant.
