The ibmtr-2.x.xx.sram.patch file contains the changes required
to allow the IBM ISA Token Ring adapters that support paging of
on board shared RAM to do so. 

This patch has been tested so far on the:
 1. IBM Auto 16/4 Token Ring ISA adapter
 2. IBM Turbo 16/4 Token-Ring ISA adapter
 3. IBM Turbo 16/4 Token Ring PCMCIA adapter
 4. 3Com 3C389 Megahertz Token Ring PCMCIA adapter

In both cases LANAID was used to setup the adapters PnP configuration
with a RAM address of 16K (ie. 0C8000-0CBFFF).

With these changes the driver will use this 16K as a window to access
all 64K of the on board shared RAM. This allows the user to have more
(or larger) receive buffers while still only requiring a mapped memory
range of 16K.

This patch is a replacement for the existing ram patch done by Dave Grothe,
and incorporates many of his changes.
