node_address
Overrides the network address of the network adapter. Use this entry
only when there are duplicate addresses on the network. The value is
a hexadecimal string of 12 digits enclosed in quotation marks. The
address must be in the range 400000000000 through 40007FFFFFFF.
For strict IBM compatibility, use only decimal digits (0–9), as in
"400001020304." The ncrtrn driver provides a unique default value
for each network adapter.
port_address
Indicates the base I/O address for the network adapter. This entry
must match the adapter’s I/O address jumper settings. The default is
0A20 for the first network-adapter and 1A20 for the second network
adapter.
product_id
Identifies the specific network adapter. The value of this entry is a
string of up to 36 hexadecimal digits (must be an even number). Refer
to the IBM Token-Ring architecture manual for more details. The
default value for this entry is
0910F0F0F0F0F0F0F0F0F0F0F0F0F0F0F0F0.
shared_ram
Specifies the physical RAM location on the network adapter if the
default location is not adequate. Values for each ncrtrn driver must
be unique. The default value for ncrtrn$ is 0xD000, and the default
value for ncrtrn2$ is 0xD200. Valid values depend on the adapter
model and revision level. Check the documentation provided with the
adapter for an accurate list.
Note The NCR Token-Ring adapter may not perform properly if
installed on an 80486 computer and subjected to heavy use.
