+@section Introduction
+
+An RTEMS Board Support Package (BSP) must be designed
+to support a particular processor and target board combination.
+This chapter presents a discussion of PA-RISC specific BSP
+issues.   For more information on developing a BSP, refer to the
+chapter titled Board Support Packages in the RTEMS C
+Applications User's Guide.

+@section System Reset
+
+An RTEMS based application is initiated or
+re-initiated when the PA-RISC processor is reset.  The behavior
+of a PA-RISC upon reset is implementation defined and thus is
+beyond the scope of this manual.

+@section Processor Initialization
+
+The precise requirements for initialization of a
+particular implementation of the PA-RISC architecture are
+implementation defined.  Thus it is impossible to provide exact
+details of this procedure in this manual.  However, the
+requirements of RTEMS which must be satisfied by this
+initialization code can be discussed.
+
+RTEMS assumes that interrupts are disabled when the
+initialize_executive directive is invoked.  Interrupts are
+enabled automatically by RTEMS as part of the initialize
+executive directive and device driver initialization occurs
+after interrupts are enabled.  Thus all interrupt sources should
+be quiescent until the system's device drivers have been
+initialized and installed their interrupt handlers.
+
+If the processor requires initialization of the
+cache, then it should be be done during the reset application
+initialization code.
+
+Finally, the requirements in the Board Support
+Packages chapter of the C Applications User's Manual for the
+reset code which is executed before the call to initialize
+executive must be satisfied.
