+@chapter BSP Questions
+
+The items in this category provide answers to questions
+commonly asked about BSPs.
+
+@section What is a BSP?
+
+BSP is an acronym for Board Support Package.
+
+A BSP is a collection of device drivers, startup code, linker scripts,
+and compiler support files (specs files) that tailor RTEMS for a 
+particular target hardware environment.
+
+@section What has to be in a BSP?
+
+The basic set of items is the linker script, bsp_specs, and startup code.
+If you want standard IO, then you need a console driver. This is needed
+to run any of the RTEMS tests.  If you want to measure passage of time,
+you need a clock tick driver.  This driver is needed for all RTEMS tests 
+EXCEPT hello world and the timing tests.  The timer driver is a benchmark
+timer and is needed for the tmtests (timing tests).  Sometimes you will
+see a shmsupp directory which is for shared memory multiprocessing
+systems.  The network driver and real-time clock drivers are optional
+and not reqired by any RTEMS tests.
