"You may set the PC4 adapter to any one of the I/O Addresses
listed.  The first choice is recommended.  Make your selection
by using the F5=Previous or the F6=Next keys.  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 PC4 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 by using the
F5=Previous or the F6=Next keys.  We recommend you select the
first level listed, DMA level 5.  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 PC4 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.  Select this option using the F5=Previous
and the F6=Next keys."

  Prompt "Preempt Count Select"
      choice "7 Bytes"    pos[1]=X11XXXXXb
  Help
"When the PC4 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 PC4 will always transfer a maximum
of 7 bytes before relinquishing control of the channel."
