+ZDS-II Compiler Versions
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Different configurations have been build for this board using ZDS-11
+Versions 4.11.0 and 4.11.1.  You have to check the files */Make.defs
+to see how the build is configured:  Check the definitions of
+ZDSVERSION (if present) and ZDSINSTALLDIR.
+
+NOTE:  Different versions of the ZDS-II compiler may also require
+different versions of .linkcmd and .zdsproj files as well.
+
+Version 4.11.0
+
+  Although it compiles without error, the 4.11.0 compiler generates
+  bad code on one of the files, mm/mm_initialize.c.  Below is a simple work-
+  around.

+
+   UPDATE:  I don't know if 4.11.1 has this same problem (I bet not since
+   I submitted the bug to ZiLOG), but I have permanently worked around the
+   above problem for all ZiLOG compiler.
+
+Version 5.1.1
+
+  On June 22, 2011 I verified that these configurations build successfully
+  with the 5.1.1 ZDS-II version.  All that is required to used ZDS-II is
+  to modify the Make.defs file so that the correct version is used.  That
+  version should also be changed in the (optional) setenv.sh file.
+
+  The above kludge for 4.11.0 is not required.
+
+  I had to make additional changes to the ZDS path in Make.defs (and also
+  in setenv.sh) when the 32-bit ZDS-II tools are installed on my 64-bit
+  Windows 7 system.
+  
+Other Versions
+  If you use any version of ZDS-II other than 4.11.0 or if you install ZDS-II
+  at any location other than the default location, you will have to modify
+  two files:  (1) configs/ez80f910200zco/*/setenv.sh and (2)
+  configs/ez80f910200zco/*/Make.defs.
+
+Configuration Subdirectories
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+src/ and include/
+    These directories contain common logic for all ez80f910200zco
+    configurations.
+
+Variations on the basic ez80f910200zco configuration are maintained
+in subdirectories.  To configure any specific configuration, do the
+following steps:
+
+   cd <nuttx-top-directory>/tools
+   ./configure.sh ez80f910200zco/<sub-directory>
+   cd <nuttx-top-directgory>
+   make
+
+Where <sub-directory> is the specific board configuration that you
+wish to build.  The following board-specific configurations are
+available:
+
+dhcpd:
+    This builds the DCHP server using the examples/dhcpd application
+    (for execution from FLASH.) See examples/README.txt for information
+    about the dhcpd example.
+
+httpd:
+    This builds the uIP web server example using the examples/uip application
+    (for execution from FLASH). See examples/README.txt for information
+    about ostest.
+
+ostest
+    This builds the examples/ostest application for execution from FLASH.
+    See examples/README.txt for information about ostest.
+
+nsh
+    This configuratino builds the NuttShell (NSH).  That code can be
+    found in examples/nsh.  For more information see:  examples/nsh/README.txt
+    and Documentation/NuttShell.html.
+
+nettest
+    This configuration is used for testing the eZ80F91 EMAC driver.  It
+    builds examples/nettest.  See examples/README.txt for more information
+    about nettest.
+
+poll
+    This configuration is also used for testing the eZ80F91 EMAC driver.  It
+    builds examples/poll.  See examples/README.txt for more information
+    about the poll test.
+
+Check out any README.txt files in these <sub-directory>s.
