The following table summarizes the possible entries and values in the
[ncrtrn] section of the LAN Manager PROTOCOL.INI file:
Entry Units Range Default
drivername — — ncrtrn$ or ncrtrnn$
interrupt — 2–7 2
max_xmt_size bytes 64–4472 2034
node_address hex. 12 hex. digits See explanation

shared_ram hex. CA00–D600 See explanation
Entries in the [ncrtrn] section of the LAN Manager PROTOCOL.INI file
have the following meanings:
drivername
Identifies the driver name of the network device driver. The base
portion of the filename, plus a digit when more than one Token-Ring
driver is installed, is the drivername. The drivername is ncrtrn$ for
the first Token-Ring driver and ncrtrn2$ for the second.
interrupt
Indicates the interrupt level of the network adapter. The default value
for ncrtrn$ is 2, and the default value for ncrtrn2$ is 3. Values for
each ncrtrn driver must be unique.
Note On an 80286 or 80386 computer, if you specify interrupt level
2, it is redirected to interrupt level 9 because the cascaded
programmable interrupt control (PIC) is already using interrupt level
2.
max_xmt_size
Specifies the size of the transmit buffers in bytes. The default is 2034
bytes.
