+= Pc386 =

+
+The PC386 BSP is designed to support a wide variety of PC clones and supports "variants" for the most popular CPU models.  The availablility of these variant builds makes it possible to build a BSP which is optimized for a particular CPU model.  Currently, the following variants are available:
+
+ * pc386 - i386DX class CPU with i387 FPU
+ * pc386dx - i386DX class CPU without an FPU
+ * pc486 - i486 class CPU with integrated FPU
+ * pc586 - Pentium class CPU
+ * pc686 - Pentium II class CPU
+ * pck6 - AMD K6 CPU
+
+More variants can be added to take advantage of GCC optimizations for newer CPUs or to take advantage of features in newer CPUs.
+
+Instructions are available for using this BSP with the PC simulator [wiki:Developer/Simulators/Bochs Bochs].

+= Embedded PC Platforms =

+
+There are a wide variety of embedded PC platforms.  Specific instructions are available for the following:
+
+ * TBD - want pages specific to Bobcat, DIMMPC, etc.
+= Serial Port as Console =
+
+
+If you are willing to set a define and recompile, any serial port can be forced to be the console rather than the video.  In addition,
+Eric Norum made a change that lets the BSP automatically fall back to using COM2: as a serial-line console (9600-8N1) if no video adapter is present. This allows the pc386 BSP to be used on conventional PCs with video adapters as well as with embedded PCs (PC-104) which have no video adapters. To make this change, add the '#define' line shown below (example based on rtems-ss-20030128/c/src/lib/libbsp/i386/pc386/console/console.c):
+
+{{{
+  * /
+ rtems''termios''initialize ();
+
+#define RTEMS''RUNTIME''CONSOLE_SELECT
+#ifdef RTEMS''RUNTIME''CONSOLE_SELECT
+ /*
+  * If no video card, fall back to serial port console
+
+}}}
