macroB_ADAPTORSHIFT

Constants for converting boot-style device number to type, adaptor (uba, mba, etc), unit number and partition number. Type (== major device number) is in the low byte for backward compatibility. Except for that of the "magic number", each mask applies to the shifted value. Format: (4) (4) (4) (4) (8) (8) -------------------------------- |MA | AD| CT| UN| PART | TYPE | --------------------------------
