The WD8003 can have shared memory at any number of locations.  This
is entirely under program control on the AT bus but is specified by
the feature setup disk on the PS/2.  In that case, the driver reads
the shared memory range in from the POS registers.

Our documentation specifies D0000 to void conflict with VGA controllers
which overlap the C4000 address on the AT bus, so is correct as it stands
since that is where we put it by default.

Changing the address won't fix the problem since the problem is that the
driver that shipped with TCP/IP 1.2 and earlier does not support the
WD8003E/A properly.  WD introduced a number of new members to the 8003
family that were not completely software compatible with the old driver so
new driver is required.  ISC will be shipping a new release of all the
network drivers (in a separate package) sometime in the next month or so.
This release will have a WD8003 driver that supports all currently released
WD8003* boards.

The updated driver is also available through Western Digital's bulletin
board.

The above is not an official statement from Interactive.  It just reflects
my current understanding of the problem.
