DFE-530TX Ethernet/Fast Ethernet Adapter for PCI Bus
Installation

When the preparatory procedure of auto-negotiation is completed,
then the line is ready and will provide a data channel which is
optimal for the two devices. The line will remain ready without
further auto-negotiation action until the linkage is broken. Auto-
negotiation then reoccurs at any time that the linkage is restored,
again making the line ready for optimal data communications.
About PCI Bus
Your DFE-530TX Adapter delivers outstanding performance by
fully exploiting the advanced features of your computer
•
PCI bus.
DFE-530TX Adapters utilize the Bus Master Mode of the PCI bus,
allowing direct transfers of Ethernet packet content between
computer memory and the adapter
•
controller, thus minimizing
network demand on the CPU. The adapter
•
controller function
provides the additional benefit of reduced command processing
overhead.
The working relationship between a DFE-530TX 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.
