"Use function keys 'F5' and 'F6' to select
the Bus Master Arbitration Level.

You can disable the Bus Master capability by selecting 
'Disable Bus Master'.  Disabling Bus Mastering degrades
performance, and we do not recommend that you do so.
Choose an arbitration level that will not be used by
any other adapter in the same computer.  Note that
arbitration levels are also priority levels.  Level 0
is the highest priority; Level 14 is the lowest priority."

  Help
"Enabling the Fairness feature ensures that a Bus Master adapter
cannot monopolize the bus.  The Fairness feature enables an
algorithm that periodically gives low-priority devices access to
the bus over higher-priority devices.  You should generally 
enable Fairness, especially if your computer uses more than one
Bus-Mastering device."
