slot. One of the connectors on the back of
the unit is connected to an 802.3 compatible Local Area Net-
work. The LNE390 acts as a complete interface between the
software running of the host system and any other node on the
LAN. Figure l-1 shows a basic block diagram of the
The LNE390 off-loads most of the low-level LAN management
functions from the host system. These functions are per-
formed by the National Semiconductor
NIC chip,
which runs under control of the software in the host system.
Each operating system supported by the
is provided
a special driver which provides a software interface be-
tween the operating system and the LNE390. In the case of
DOS, the driver is loaded as a TSR (Terminate and Stay
Resident) program which is combined with a ‘Network Shell
that provides network services to the DOS user. For Novell
Netware 3.1 x, the driver is loaded with a LOAD command after
the server system has been started. UNIX systems (both

require the driver to be linked into the operating
system kernel before network services can be used.
