Chapter 9 Network Device Driver Options 195
Entries in the [ibmtok] 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 ibmtok$
for the first Token-Ring driver, ibmtok2$ for the second, and so on.
earlyrelease
Specifies the “early token release” option for IBM Token-Ring 16/4
network adapters. This entry is a function that reduces the average
time another network adapter must wait to gain access to the
network. Adapters that don’t support early token release ignore this
entry. This entry is not followed by an equal sign.
maxtransmits
Sets the number of transmit-queue entries in the driver. On an
MS OS/2 server, this number should equal the transmit window size
times the maximum number of sessions.
netaddress
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 double 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".
primary or alternate
Identifies driver assignments when more than one Token-Ring
network adapter is installed. A primary entry denotes the first
(primary) adapter; alternate denotes the second adapter. If these
entries are missing, the ibmtok driver defaults to the first adapter it
finds, trying primary first. This entry is not followed by an equal
sign.
Note When installing two IBM Token-Ring adapters in a
computer, one of the adapters must have a primary entry in the
PROTOCOL.INI file, while the other adapter must have an alternate
entry. Be sure to jumper the two adapters to different ROM
addresses. For more information, see the manuals for the IBM Token-
Ring adapters.
product_id
Identifies the specific 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 0110F0F0F0F0F0F0F0F0F0F0F0F0F0F0F0F0.
