NOTE's: (*1, *2, *3, *4)

1.  B0000-B7FFF can be used by other application if MONO video mode
    is not used.
2.  The exact boundaries are subject to change by BIOS version.
    Look in Configuration Utility for exact space used in this range.
3.  CA000-CFFFF area is available for UMB, not for PCMCIA.
    The area available for PCMCIA is D0000-DFFFF.
4.  C6000-a7FFF area is available for UMB, not for PCMCIA.
    The area available for PCMCIA is C8000-DFFFF.
