+The requirements for this BSP are only that the GAS used supports the
+.code16 directive. The GAS released with any GCC version 2.8.0 or better
+is required. The BSP was built with an egcs snapshot pre-1.0.2 and
+post-1.0.1. However, any egcs should work.
+
+
+The only "real" differences are in bspstart.c, where the initialization now
+configures all available RAM, (after setting up the Workspaces) as heap.
+The location of the stack was changed so that the heap was not trapped
+between low memory and the stack; the stack comes before the heap.
