Chapter 8 About Network Device Drivers 107

Protocol Manager

LAN Manager supports the use of multiple protocols. The most

practical limit to the number of protocols a computer can support is its

memory capacity. Your computer could be connected to as many as 12

networks, of which LAN Manager can manage one, some, or all.

LAN Manager’s Protocol Manager module coordinates communication

among drivers and adapters.

The Protocol Manager driver (PROTMAN.OS2 or PROTMAN.DOS) is

listed before other network device drivers in CONFIG.SYS so that it

will load first. When Protocol Manager loads, it reads the

PROTOCOL.INI file, which contains configuration data for all the

protocol and media-access control drivers installed on your computer.

(The directory containing PROTOCOL.INI is specified by the /i: option

on the CONFIG.SYS device line that defines the Protocol Manager

driver.) The Protocol Manager uses the data in the PROTOCOL.INI file

to bind (tie together) the device drivers so they can work together.

Note

If only a monolithic driver is installed, the Protocol Manager is not

used.

For more information about the configuration data for Protocol

Manager, see “

The PROTOCOL.INI File,

” later in this chapter. For

more information about binding, see the Microsoft/3Com LAN Manager

Network Driver Interface Specification (NDIS), version 2.01.

The NetBIOS Interface

The NetBIOS interface is used by applications to communicate with

NetBIOS-compliant transports. The LAN Manager redirector program

(installed as NETWKSTA.SYS on an OS/2 workstation) is an example

of such an application.

By default, LAN Manager supports a NetBIOS 1.0 interface that is

installed with the redirector. Also provided with LAN Manager, but not

installed, is a NetBIOS 3.0 interface for OS/2 workstations. This

interface works with the NetBEUI protocol driver only, and supports

the IBM Ring 0 and Ring 3 interface specification.

To install the NetBIOS 3.0 interface, edit your CONFIG.SYS and

LANMAN.INI files, making the changes described in the following

sections.
