+*****************************************************************************
+** ChibiOS/RT port for ARM7TDMI LPC214X.                                   **
+*****************************************************************************
+
+** TARGET **
+
+The demo runs on an Olimex LPC-P2148 board. The port on other boards or other
+members of the LPC2000 family should be an easy task.
+
+** The Demo **
+
+The demo blinks the leds on the board by using multiple threads. By pressing
+the buttons on the board it is possible to activate the buzzer and send a
+message over the serial ports.
+See main.c for details. Buzzer.c contains an interesting device driver
+example that uses a physical timer for the waveform generation and a virtual
+timer for the sound duration.
+
+** Build Procedure **
+
+The demo was built using the YAGARTO toolchain but any toolchain based on GCC
+and GNU userspace programs will work.

+*****************************************************************************
+** ChibiOS/RT port for x86 into a Win32 process                            **
+*****************************************************************************
+
+** TARGET **
+
+The demo runs under any Windows version as an application program. The serial
+I/O is simulated over TCP/IP sockets.
+
+** The Demo **
+
+The demo listens on the two serial ports, when a connection is detected a
+thread is started that serves a small command shell.
+The demo shows how create/terminate threads at runtime, how listen to events,
+how ho work with serial ports, how use the messages.
+You can develop your ChibiOS/RT application using this demo as a simulator
+then you can recompile it for a different architecture.
+See demo.c for details.
+
+** Build Procedure **
+
+The demo was built using the Visual Studio 7, any later version should work.
