"This determines the interrupt level of the EtherLink/MC 32.  The
interrupts can be shared with another device, however the software
drivers for both devices must support interrupt sharing.  You may be
able to improve performance by selecting a level that is not used by
another device."

masters and in most instances should be enabled.  In a system where it
is desired that a higher priority device have increased bus utilization,
fairness may be disabled."

NamedItem
Prompt "Address Burst Management"

   choice "16-byte boundary" pos[3]=xxxxxx01b
   choice "32-byte boundary" pos[3]=xxxxxx10b
   choice "64-byte boundary" pos[3]=xxxxxx11b

Help
"The Address Burst Management feature enables the Etherlink/MC 32 to
relinquish control of the Micro Channel Bus at specific address boundary
crossings.  As an example, if the 16-byte boundary Address Burst
Management is selected, the Bus Master relinquishes bus control as the
address increments from xx0Fh to xx10h.
In some system configurations, the Address Burst Management feature may
provide improved performance, but generally it should be disabled."

Help
"The active connector is determined by the selection of the Transceiver
Type.  Check the cabling system in your area to determine which
connector should be used.  If you have a thin ethernet network and wish
to connect using a T-connector, select On-board.  If you have the thick
drop cable from an external transceiver and wish to attach to the 15-pin
AUI cable, select External."
