+^^^^^^^^^^
+
+ZDS-II Compiler Versions
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+4.11.0
+  This is the only version that this code has been built against.
+
+  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.
+
+    --- mm/mm_initialize.c.SAVE	2008-02-13 08:06:46.833857700 -0600

+   /* Set up global variables */
+
+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:
+
+ostest
+    This builds the examples/ostest application for execution from FLASH.
+    See examples/README.txt for information about ostest.
+
+Check out any README.txt files in these <sub-directory>s.
