Network Operating Systems

The Ethernet interface is typically connected in a network controlled by a network operating
system. The network operating system may be part of the computer's operating system or be
provided separately. For example, Windows® NT provides the network operating system as part of
computer's operating system. Novell's NetWare™ provides a separate, add-on network operating
system for DOS and Windows. The network operating system provides file server and network
services to the distributed systems connected to the network. Each node on the network must have
a compatible network operating system installed as well.
Modern network architectures are based on the OSI model, which defines layers of software
between the network hardware, the network operating system, and the applications that use the
network services. The actual Ethernet cable and the Little Board/P5x hardware interface are at the
bottom level. A driver program at the next level handles communication between the hardware and
the operating system, masking any unique differences in the hardware from the layers above it,
including the network operating systems.

Network OS Drivers

The Little Board/P5x Ethernet subsystem uses AMD PCnet-family drivers, available from AMD.
The driver is the only unique software you need to use the Little Board/P5x. The supported network
operating systems provide the other software layers normally provided in the OSI model. These
include:
! AHSM ODI Drivers (DOS, OS/2, Server)
! CHSM ODI Driver for NetWare 5.0
! NDIS 2.0.1 Drivers (DOS version 6.x, OS/2 version 3.x and 4.x)
! NDIS 3.x MAC Drivers (for WFW 3.11; NT versions 3.5, 3.51, 4.0; Win95)
! NDIS 3.x Miniport Drivers (for Windows 95 and Windows NT 3.51)
! NDIS 4.x Driver (for Windows NT 4.0 and Windows 95 OSR 2)
! Novell UnixWare Drivers (for v1.1 and 2.0)
There are also drivers for various flavors of UNIX and for other operating systems. AMD also
supplies diagnostic software for testing your Ethe rnet se tup.

Ethernet Setup
This section describes how to configure and connect the Ethernet LAN interface.
There are no jumpers to set on the Ethernet interface, and no hardware configuration, other than
connecting the network cable to an appropriate connector.
Software configuration of the Ethernet interface includes the following steps:
! In Setup, enable the Ethernet interface.
