BIOS: Report I/O and local APIC ranges in E820h memory map.

File:

trunk/src/VBox/Devices/PC/BIOS/notes.txt

-              r49286
+              r59354
   executed on 386+ processors.
+- Windows NT 3.5 and 3.51 with MPS HAL requires that INT 15h/E820h return the
+  I/O APIC range as reserved, or not return any ranges at all just below 4GB.
+  Otherwise the NT kernel will crash early during init due to confusion about
+  the top of memory.
