+Installing the software:
+------------------------
+
+  - The software installation has been tested under Windows XP.
+    It should work under Windows 2000 and Windows Vista too. 
+
+  - Create the directory "C:\Dvpt_tools"
+
+  - Unpack the file "TI_toolchain.zip" to "C:\Dvpt_tools"
+
+  - Install cygwin-B20.exe to "C:\Dvpt_tools\cygnus", you don't have to
+    include the Cygwin Installation in the PATH environment variable.
+
+  - Install ActivePerl-5.6.1.629-MSWin32-x86-multi-thread.msi 
+    to "C:\Dvpt_tools\Perl"
+  
+  - Install j2sdk-1_4_2_02-windows-i586-p.exe if you don't already have
+    a newer version of Java installed.
+
+
+Building the GSM firmware:
+--------------------------
+
+  - Change to the "g23m" directory of the source code and open a
+    command prompt window (CMD.EXE).
+
+  - Run the batch file "build.bat".
+
+  - If something goes wrong, please have a look at the file "report.txt",
+    it contains the output of the build process.
+    
+  - Please be aware that recreating the "pdt_2091.mak" makefile should not
+    be done because "pdt_2091.mak" contains some manual adjustments. Usually
+    recreating the makefile isn't necessary at all.
+
+
+Misc:
+-----
+
+  - The TI Linker (Visual Linker V 1.9902) produces different result image 
+    files depending on various circumstances. The result depends on:
+
+    * Linker is called directly or from a sub-process (e.g. from MAKE).
+
+    * Map file already exists or not.
+
+    * How many file are in the output directory.
+
+    There might be even more factors which influence the behaviour. Till now
+    it seems that all the different image files produced from the same input
+    files are valid and working. The problem from this behaviour of the linker
+    is that image files can't be compared, even if they were produced from the
+    same input files.
