  42  * Options :
  43  * AUTOSENSE - if defined, REQUEST SENSE will be performed automatically
  44  *      for commands that return with a CHECK CONDITION status.
  45  *
  46  * LIMIT_TRANSFERSIZE - if defined, limit the pseudo-dma transfers to 512
  47  *      bytes at a time.  Since interrupts are disabled by default during
  48  *      these transfers, we might need this to give reasonable interrupt
  49  *      service time if the transfer size gets too large.
  50  *
  51  * PSEUDO_DMA - enables PSEUDO-DMA hardware, should give a 3-4X performance
  52  * increase compared to polled I/O.
  53  *
  54  * PARITY - enable parity checking.  Not supported.
  55  *
  56  * SCSI2 - enable support for SCSI-II tagged queueing.  Untested.
  57  *
  58  * UNSAFE - leave interrupts enabled during pseudo-DMA transfers.  This
  59  *          parameter comes from the NCR5380 code.  It is NOT unsafe with
  60  *          the PAS16 and you should use it.  If you don't you will have
  61  *          a problem with dropped characters during high speed
  62  *          communications during SCSI transfers.  If you really don't
  63  *          want to use UNSAFE you can try defining LIMIT_TRANSFERSIZE or
  64  *          twiddle with the transfer size in the high level code.
  65  *
  66  * USLEEP - enable support for devices that don't disconnect.  Untested.
  67  *
  68  * The card is detected and initialized in one of several ways :
  69  * 1.  Autoprobe (default) - There are many different models of
  70  *     the Pro Audio Spectrum/Studio 16, and I only have one of
  71  *     them, so this may require a little tweaking.  An interrupt
  72  *     is triggered to autoprobe for the interrupt line.  Note:
  73  *     with the newer model boards, the interrupt is set via
  74  *     software after reset using the default_irq for the
  75  *     current board number.
  76  *
  77  * 2.  With command line overrides - pas16=port,irq may be
  78  *     used on the LILO command line to override the defaults.
  79  *
  80  * 3.  With the PAS16_OVERRIDE compile time define.  This is
  81  *     specified as an array of address, irq tuples.  Ie, for
  82  *     one board at the default 0x388 address, IRQ10, I could say
  83  *     -DPAS16_OVERRIDE={{0x388, 10}}
  84  *     NOTE:  Untested.
  85  *
  86  * 4.  When included as a module, with arguments passed on the command line:
  87  *         pas16_irq=xx         the interrupt
  88  *         pas16_addr=xx        the port
  89  *     e.g. "modprobe pas16 pas16_addr=0x388 pas16_irq=5"
  90  *
  91  *     Note that if the override methods are used, place holders must
  92  *     be specified for other boards in the system.
  93  *
  94  *
  95  * Configuration notes :
  96  *   The current driver does not support interrupt sharing with the
  97  *   sound portion of the card.  If you use the same irq for the
  98  *   scsi port and sound you will have problems.  Either use
  99  *   a different irq for the scsi port or don't use interrupts
 100  *   for the scsi port.
 101  *
 102  *   If you have problems with your card not being recognized, use
 103  *   the LILO command line override.  Try to get it recognized without
 104  *   interrupts.  Ie, for a board at the default 0x388 base port,
 105  *   boot: linux pas16=0x388,255
 106  *
 107  *   SCSI_IRQ_NONE (255) should be specified for no interrupt,
 108  *   IRQ_AUTO (254) to autoprobe for an IRQ line if overridden
 109  *   on the command line.
 110  *
 111  *   (IRQ_AUTO == 254, SCSI_IRQ_NONE == 255 in NCR5380.h)
