//  CARDTMV1.C 
//
//  TMV1 Adapter Specific File
//
//  See also cardtxxx.h, cardtxxx.h may redefine some functions with #defines.
//
//  Revisions:
//      09-01-92 KJB First.
//      03-26-93  JAP   Fixed up typedef and prototype inconsistencies
//      04-05-93  KJB   Fixed definition problem for WINNT.
//                          Involving CardAddressRange...
//      04-22-93  JAP   Added AdapterInterrupts[] and CardGetIRQ().
//      05-05-93  KJB   Fixed CardSetInterruptLevel so that it calls
//                          MV101SetInterruptLevel like it should.
//      05-12-93  JAP   Altered CardGetShortName() to return only
//                          the type of card.
//      05-13-93  KJB   Added CardParseCommandString for card specific
//                      standard string parsing across platforms.
//                      Changed CardCheckAdapter to accept an
//                      Initialization info from command line, ie
//                      force bi-directional ports, etc.
//                      All functions that used to take an PBASE_REGISTER
//                      parameter now take PWORKSPACE.  CardCheckAdapter
//                      takes the both the PBASE_REGISTER and the
//                      PWORKSPACE parameters. Auto Request Sense is
//                      now supported.
//      05-13-93  KJB   Merged Microsoft Bug fixes to card detection.
//      05-14-93  KJB   Removed P3CDoIo, it did not work for scatter gather.
//      05-17-93  KJB   CardAddressRangeLength now return 0xffff.
//                      Fixed compiler warnings.
