** Change History (most recent first):

** 

**   <1.4>  970207      Quinn   Renamed to RamDiskCommon.h.  Now only contains stuff

**                              that actually needs to be shared.  The other stuff

**                              has been made private to the corresponding source file.

**   <4>    960807      BL¡B    Added DriverGestalt.h, set no OLDROUTINENAMES

**   <3>    10/14/93    JML     Added Panic debug macros and changed preprocessor constants

**                              to enums.

**   <2>     6/13/93    gs      Move dCtlFlag bits from RamDRVR.c and cleanup header.

**   <1>     8/24/92    gs      first checked in
