1 Introduction
Product Overview
PLANET ENW-9501Plus PCI adapter is a 
high performance adapter compatible with 
version 2.0 of the PCI local bus 
specification and support Plug and Play 
(PnP) function, making it full autoconfiguration.
ENW-9501Plus supports full-duplex mode. 
Full-duplex mode can be used to obtain 
throughput of up to 20/200Mbps when 
connecting through an Ethernet 
Switching Hub. It also uses the Bus 
Mastering features of the PCI bus to give 
high performance with a low CPU 
utilization. 
Bus Mastering adapter and other 
peripherals allow greatly reduced CPU 
utilization ratios, resulting in lower 
latency and better overall performance.
ENW-9501 Plus includes a cmplete set of 
drivers for popular network operating 
systems. The optional Boot ROM device 
allows the diskless workstation to be 
connected to the network.
With the Auto-Negotiation technology, 
network speed is auto detected. When you 
connect ENW-9501Plus to 10Base-T Hub 
via UTP cable, the network speed 
becomes 10Mbps. Similarly, if you 
connect ENW-9501Plus to 100Base-TX 
Hub, the network speed is 100Mbps. If 
the hub is a switching hub which supports 
Auto-Negotiation, then the speed will be
optimized as soon as UTP cable attached. 
(20/200Mbps) 
The Product supply with drivers including 
Novell Netware 3.x, 4.x, NDIS for 
Microsoft LAN Manager and Windows 95, 
Windows NT, and a Packet Driver for
