RUNNING LANTASTIC AI WITH A WESTERN DIGITAL ELITE SERIES ADAPTER

         The Elite 8 (8-bit) and Elite 16 (16-bit) are the current
adapters from Western Digital. They are multi-media adapters,
supporting the thick (10BASE5), thin (10BASE2; also called
cheapernet or coaxial), and the twisted pair (10BASET) subsets of
the IEEE 802.3 Ethernet specifications. Both adapters are supported
with the WD8003.EXE program that is made available with
LANTASTIC/AI 4.0.

         There are three jumpers in the upper middle section of the
adapter. Two of them provide a predefined combination of IRQ,
IOBASE and RAMBASE. It is very important that our WD8003 program's
options match up with the hardware configuration. If neither of
these two predefined combinations works, then you need to place
that jumper on the SOFT setting, and use the WD-supplied EZSETUP
program to configure the hardware.

TO TRY ONE OF THE PRE-DEFINED COMBINATIONS OF IRQ, IOBASE AND
RAMBASE:          
1) Jumper the appropriate pin, and take note of what IRQ, IOBASE  
   and RAMBASE it is providing.          
2) Run our WD8003 program, and make sure the software switches    
   match the hardware configuration.

TO TRY A COMBINATION OF IRQ, IOBASE AND RAMBASE THAT IS NOT OFFERED
AS A PREDEFINED OPTION.           
1) Jumper the SOFT pin.           
2) Run the Western Digital-supplied utility called EZSETUP to     
   configure the hardware.          
3) Run our WD8003 program, and make sure the software switches    
   match the hardware configuration.

         Do not use the Western Digital NETBIOS software. However,
the EZSETUP and the diagnostic programs should be run.

         After running the INSTALL program, our device driver
called WD8003.EXE will be in the LANTASTI subdirectory, and will be
the first program that you run. However, there is currently a
problem with the WD8003 program where it will inadvertently take up
more high memory than it should. ARTISOFT suggests that you start
out using the 8-BIT software switch, at least until you can log in,
and use the network to COPY large amounts of files. Once that
works, try it without using the 8-BIT software switch.

         EXAMPLE: IF the jumper were on the SOFT setting, AND IF
EZSETUP had told the adapter to use and IRQ of 10 (NOTE: IRQs of 10
or 15 need to have the 16-bit adapter in a 16-bit slot), an IOBASE
of 300 and a RAMBASE of D800, then the WD8003 command line,
including the 8-BIT software switch, would look like this (it does
not need to be in caps):

                 WD8003 IRQ=10 IOBASE=300 RAMBASE=D800 8-BIT
