Appendix B. NDIS 2 device driver parameters

 

The following table describes the NDIS 2 device driver parameters. For sample

 

PROTOCOL.INI files, see Figure 3 on page 58 and Figure 4 on page 58.

Table 9. DOS and OS/2 NDIS device driver parameters in PROTOCOL.INI

Parameter

Explanation

 

 

NetAddress

Use this parameter to specify a locally administered address for the adapter. The address

 

must be enclosed in double quotes (“ ”) and be unique among all the addresses on the

 

network.

 

 

The adapter can be known on the network by its universally administered address (the

 

address encoded in the adapter’s memory at the factory) or a locally administered address

 

(a unique, user-assigned address).

 

The universally administered address is the default value. That address appears on the

 

adapter bracket. See Figure 2 on page 44 for an illustration.

 

Valid values: 400000000000to 7FFFFFFFFFFFin hex

 

 

DataRate

Used for configuring the ring speed of the adapter. It is recommended for servers that the

 

DataRate be set to M16 or M4, and clients be set to Auto. This parameter is ignored for 100

 

Mbps network operation.

 

Valid values:

 

AUTO AutoSense – automatic ring-speed detection.

 

 

Note: The adapter will not function with AutoSense if it is the first one on the ring.

 

 

AutoSense is not designed for changing ring speed while the adapter is operational.

 

 

It is usually necessary to reload the driver.

 

M16

16-Mbps ring-speed operation.

 

M4

4-Mbps ring-speed operation.

 

The default is AUTO.

 

 

EnableTxEofInt

This parameter specifies whether the Transmit End of Frame Interrupt is enabled.

 

Valid values:

 

Yes

Indicates that the interrupt will be recognized by the interrupt handler.

 

No

Indicates that the interrupt will not be recognized by the interrupt handler. This

 

 

value is preferable in some environments (such as a server environment) to reduce

 

 

the number of times the interrupt handler is invoked. This can result in reduced

 

 

CPU utilization and increased performance.

 

The default is Yes.

 

 

MaxTransmits (OS/2

This parameter specifies the maximum number of transmit queue entries. The value should

only)

be set high enough to accommodate the sum of all MaxTransmits for all protocol drivers

using the adapter concurrently. Valid values: 1 to 128

The default is 31.
