The device driver needed for the adapter to operate with the IBM LAN Client software is provided on the adapter product CD-ROM. The following drivers are provided:

• TOKEN.LAN -- for ISA, Micro Channel^(R), and PCMCIA token-ring adapters
• IBMMPCO.LAN -- for the IBM Auto LANStreamer PCI Adapter
• IBMTRPO.LAN -- for the IBM Token-Ring PCI Family Adapters

The installation program will copy the driver to your workstation hard disk when you tell it which adapter you will be using. It will also provide the correct load statements in STARTNET.BAT.

Supported software

IBM LAN Client provides support for the following protocols and client applications:

For DOS 5.0 or later:

• IEEE 802.2
• NetBIOS
• DOS LAN Services 5.x (with IBM Warp Server)
• Novell IntranetWare Client for DOS and Windows 3.1 (with Novell NetWare 2.15c and later)
• PC3270 Version 4.x
• DCAF (Version 1.3 + CSDs)
• Artisoft LANtastic Version 6.0
• Attachmate 3270 Emulation
• LANDP^(R) (If you are using Version 2, make sure that the service level of LAN.EXE is MS004 or later.)

For Windows^(R) 3.1, Windows 3.11, and Windows for Workgroups 3.11:

• IEEE 802.2
• NetBIOS
• DOS LAN Services 5.x (with IBM Warp Server)
• Novell IntranetWare Client for DOS and Windows^(R) 3.1 (with Novell NetWare 4.x)
• AS/400^(R) for Windows (Version 4.0, V3R1M0, and V3R1M1)
• TCP/IP using Winsock 1.1 or 1.2
• PC3270/Windows Version 4.x
• Artisoft LANtastic Version 6.0
• APPC/Windows

Supported operating systems

IBM LAN Client supports the following desktop operating systems:

• MS-DOS 5.x and 6.x
• PC-DOS 5.x, 6.x, and 7.0
• Windows 3.1 and 3.11, in enhanced mode
• Windows for Workgroups 3.11

Restrictions for this release

The following restrictions apply for this release of IBM LAN Client:

• IBM LAN Client will operate with only one adapter.
• IBM LAN Client does not support the RPL function.

Overview

IBM LAN Client provides program interfaces to support network application programs using selected IBM Token-Ring adapters. It allows a DOS/Windows client workstation to communicate with an IBM LAN Server at Version 3.0, 4.0, and Warp Server, or with a Novell NetWare Server at Version 2.15c or later, or to use TCP/IP applications in Windows. (The IBM and Novell client code is included with this package but, with the exception of PING, TCP/IP applications are not.) In addition, support is provided for programs written to the NetBIOS or IEEE 802.2 application programming interfaces.

Benefits

• Requires as little as 4 KB conventional memory. (See DOS conventional memory usage reduction for more details.)
• Uses one common environment for concurrent multiple protocols.
• One or more of NetBIOS, IPX, TCP/IP, and IEEE 802.2.
• Does not require shim modules, such as ODINSUP and LANSUP.
• Includes client software for attachment to Novell NetWare Servers or IBM LAN Servers.
• Includes DOS LAN Services 5.x.
• Includes Novell IntranetWare Client for DOS and Windows 3.1.
• Provides full access to essential NetWare services such as NetWare Directory Services (NDS).
• Provides improved connection reliability, including the ability to auto-reconnect open files.
• Provides enhanced large Internet packet (LIP) and packet burst support.
• Includes an installation tool with a graphical user interface (GUI) for easy installation of client software.
• Includes a command-line version of the installation tool for use by network administrators who are installing on a large number of workstations.
• Allows the same adapter device driver to be used for client workstations and for Novell NetWare servers, reducing support complexity.

DOS conventional memory usage reduction

IBM LAN Client minimizes the use of DOS conventional memory for network communications. With LAN Client, the LAN adapter drivers and protocol stacks no longer require large amounts of DOS memory. Table 9 shows the memory requirements LAN Client, compared with existing implementations. This table shows how much DOS conventional memory is used by LAN Client for three popular communication protocols, compared with current usage.

Protocol	Before IBM LAN Client	With IBM LAN Client
IPX	59 KB	5 KB
IEEE 802.2	95 KB	4 KB
NetBIOS	95 KB	4 KB

Installation and configuration

1. Run LCINST.EXE from the root directory of the CD-ROM if you have one of the IBM Token-Ring PCI Family Adapters or from the \lanclnt directory if you have the IBM Turbo 16/4 Token-Ring PC Card 2. You can also run it from the installed version of LCINST from the LAN Client diskettes or the self-extracting package file (LCPKG.EXE).

   Note:

   To install LCINST to a hard disk from the LAN Client diskettes, insert LAN Client diskette 1 in drive A and enter install.

2. Select your software environment from the first IBM LAN Client Installation panel (DOS, Windows, or Windows for Workgroups).
3. Select your adapter from the IBM LAN Client Adapter Selection panel.
4. Continue to the IBM LAN Client Application and Protocol Selection panel.
5. Select the protocols to install and click OK.
6. Select the tabs on the IBM LAN Client Configuration panel to configure each protocol.
7. Select Install.
8. Reboot your computer when prompted.

   Note:

   The command line version (LCINSTC.EXE) can also be used to install IBM LAN Client. For a list of valid parameters that can be used with the command line version, type lcinstc /h and press Enter.
