"You may set the NCR SCSI adapter to any one of the I/O
Addresses listed.  The first choice is recommended.  If 
your selection conflicts with an I/O address already 
assigned in your system, it will be marked with an asterisk
and you must select an alternate address."

  Help
"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 
asterisk and you must select an alternative level."

      Prompt "Fairness"
      choice "Fairness Enabled"    pos[1]=XXX1XXXXb
      choice "Fairness Disabled"   pos[1]=XXX0XXXXb

  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."

  Prompt "Preempt Count Select"
      choice "7 Bytes"    pos[1]=X11XXXXXb

  Help
"When the NCR SCSI Adapter detects that another adapter requires 
use of the channel, the Preempt Count feature is activated.  The 
Preempt Count is the maximum number of bytes to transfer before 
yielding control of the channel.  The Adapter will always transfer 
a maximum of 7 bytes before relinquishing control of the channel."
