 "The NCR SCSI Adapter supports the direct memory access (DMA)
 mode of data transfer.  Each DMA level has a corresponding
 priority level; the lower the DMA level, the higher the
 corresponding priority. You may select any one of the DMA
 levels listed.  We recommend you select the first level listed,
 DMA level 3.  If your selection conflicts with a DMA level
 already assigned in the system, it will be marked with an

   Help
 "If 'Fairness' is enabled, the NCR SCSI Adapter will not compete
 for the channel during the next arbitration phase if it is currently
 in control of the channel.  This allows other installed adapters
 to obtain the channel in the next sequence based on each adapter's
 assigned priority level.  When 'Fairness' is disabled, the adapter
 will compete for every arbitration phase and will obtain more than
 its fair share of channel usage.  We recommend you use 'Fairness
 Enabled' for all adapters."
