RUNNING LANTASTIC AI WITH AN SMC PC220 or PC500WS ADAPTER

         The Standard Micro Systems (SMC) PC220 and PC500WS
adapters are supported in LANTASTIC/AI 4.0 with the device driver:
SMCARC.EXE. Standard Micro Systems has informed ARTISOFT that their
compatibility testing has determined the PC550WS adapter to be
compatible too.

         After running the INSTALL program and selecting the SMC
PC220 or SMC PC500WS adapter, a program called SMCARC.DOC will be
in the LANTASTI subdirectory. PLEASE READ IT.

         The SMC PC500FS adapter is incompatible with LANTASTIC.
However, the PC500WS board can also be used in a LANTASTIC server.
The PC500WS board comes in two 'flavors', and the difference is not
reflected in the model names. The SHORT board (~5") is the one that
uses high memory, or RAMBASE, and is the compatible one. The longer
board (~6.2") does not use high memory, and is incompatible.
(Please refer to the SETTINGS document)

         There are several other SMC boards, and many more that
have the SMC ARCNET chipset that will not run with the SMCARC
driver. The reason is that the SMCARC driver has a sniffer in it
that looks for hidden registers in the most recent releases of
SMC's ARCNET boards. This was a request from SMC in exchange for
their providing the device driver to us. We enhanced the program,
adding the 'hooks' to work with LANTASTIC.
