//
//  Revisions:
//      02-01-93 KJB First.
//      02-25-93 KJB Reorganized, supports dataunderrun with long delay
//                      for under run on large xfers. Can we fix this?
//      03-22-93  KJB   Reorged for functional library interface.
//      03-26-93  JAP   Fixed up typedef and prototype inconsistencies
//      04-22-93  JAP   Added AdapterInterrupts[] and CardGetIRQ().
//      05-12-93  JAP   Altered CardGetShortName() to return only
//                          the type of card.
//      05-14-93  KJB   Removed P3CDoIo, it did not work for scatter gather.
//      05-17-93  KJB   Fixed compiler warnings.
