USING KEYWORDS FOR THE DRIVERS
The Protocol.ini file contains certain keywords that are used by the BXND20X.dos AND BXND20X.dos drivers. These
keywords are listed below:
BusNum. Specifies the number of the PCI bus on which the network adapter is located. Requires a decimal number having
a value ranging from 0 to 255.
DevNum. Specifies the device number assigned to the network adapter when it is configured by the PCI BIOS. Requires a
decimal number having a value ranging from 0 to 255.
FuncNum or PortNum. Specifies the PCI function or port number assigned to the network controller. Requires a decimal
number having a value ranging from 0 to 7.
NOTE: These keywords, BusNum, DevNum, and FuncNum (or PortNum) are needed when multiple adapters
are installed in the server and when a specific controller must be loaded in a certain order. These keywords are
used concurrently and are included for manufacturing purposes. Do not use them unless you are familiar with how
to configure PCI devices. A PCI device scan utility is needed to find this information.
LineSpeed. Specifies the speed of the network connection in Mbit/s. Requires the decimal number 10, 100, or 1000.
Technically, a line speed of 1000 Mbit/s cannot be forced and is achievable only through auto-negotiation. For the sake of
simplicity, the driver performs auto-negotiation when the line speed is set to a value of 1000.
NOTE: LineSpeed is not available with the Broadcom NetXtreme II 10 Gigabit Ethernet driver.
Duplex. Specifies the duplex mode of the network adapter. Requires a setting of either Half or Full. When this keyword is
used, the LineSpeed keyword must also be used. If neither keyword is used, the network adapter defaults to auto-
negotiation mode.
NOTE: LineSpeed is not available with the Broadcom NetXtreme II 10 Gigabit Ethernet driver.
NodeAddress. Specifies the network address used by the network adapter. If a multicast address or a broadcast address
is specified, the adapter uses the default MAC address.
Example:
[BXND20X]
DriverName = "BXND20X$"
BusNum = 3
DevNum = 14
PortNum = 2
LineSpeed = 1000
Duplex = Full
NodeAddress = 001020304050
FixCheckSumOff. Turns off the driver’s workaround for the TCP/IP stack to recognize the 1s complemented version of the
checksum.
