Enable/Disable Adapter
Use the disabled setting if you are not
using the adapter
in your system

I/O Base Address
The EtherLink/MC 32 occupies 16 bytes in
the I/O Address
space.
< "728x"
(7280-728f)>,
729x (7290-729f), 768x (7680-768f), 769x
(7690-769f), 7A8x (7a80-7a8f),
7A9x (7a90-7a9f), 7E8x (7e80-7e8f), 7E9x (7e90-7e9f)
Shared Memory Ranges
EtherLink/MC 32 requires a 16K memory
window and it may
be located at any of eight possible address ranges.
<"RANGE:D800-DBFF,
16K">, DC00-DFFF, 16K, C000-C3FF, 16K,
C400-C7FF, 16K, C800-CBFF,
16K, CC00-CFFF, 16K, D000-D3FF, 16K, D400-D7FF, 16K
Interrupt Level
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.
<"Level
10">,
11, 9, 12
Arbitration Level
Level eight has the highest priority, and
higher levels
decrease priority
<"Level
10">,
11, 12, 13, 14, 8, 9
Fairness Enable
Fairness is provides equal access is to the
host bus for
competing bus
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.
<"Enabled
" >,
Disabled
Address Burst Management
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.
<"Disabled">,
16-byte
boundary, 32-byte boundary, 64-byte boundary
Transceiver Type
The active connector is determined by the
selection of
the Transceiver
Type. 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
