Adapter Independent
Invisible LAN Operating System
for DOS and Windows 3.X
Version 4.00K

This is the Adapter Independent (AI) version of the Invisible LAN Operating System, for DOS and Windows 3.X.

The AI version supports a wide variety of network boards, manufactured by many different companies. Supported network boards include: Novell NE-2000 compatibles, Novell NE/2 compatibles, Western Digital WD-8013 compatibles, 3Com 3C509B adapters, DEC "Tulip" adapters, and IBM Token Ring.

The Invisible LAN operating system has many features, including:

• Drive and printer mapping, file sharing, and record locking.
• Print spooling with remote viewing and management of print queues.
• Electronic mail.
• Network polling, browsing, and diagnostics.
• Disk cache that supports delayed write-back, track buffering, and elevator seek.
• Security system with password protection, user- and group-based permissions, and directory-level access controls.
• Remote management of server functions, including statistics, logged-in users, activity log, and security.
• Highly configurable memory usage, supports upper memory and expanded memory.
• DOS version includes both command-line utilities and menu-driven interface.
• Windows 3.X version includes graphical interface.

The software available on this web site can be used in three ways: (a) to set up a new installation of Invisible LAN; (b) to upgrade an earlier version of the Invisible LAN software to version 4.00K; and (c) to replace an existing installation of Adapter Dependent (AD) software with Adapter Independent (AI) software. We give instructions below for each of these possibilities.

Note: Unlike earlier versions of Invisible LAN, this version does not require a serial number file.

Instructions -- For A New Installation

If you want to set up a new installation of the Adapter Independent Invisible LAN Operating System, for DOS and Windows 3.X, do this:

1. Click here to download ILAI.ZIP (1666K).
     
2. Make a directory on your hard disk to hold the Invisible LAN software. We recommend calling the directory C:\NET30. The following command is an example of how you might create the directory:
   
       MD  C:\NET30
    
3. Unzip ILAI.ZIP into the directory you just created. For example, with PKUNZIP you could use the following command:
   
       PKUNZIP  -d  ILAI  C:\NET30\
   
   Notice the -d parameter. This tells PKUNZIP to use the subdirectory information in the ZIP file.
     
4. Run SETUP30 (standard setup) or QSETUP (quick setup) to set up the Invisible LAN software. Refer to the instruction manuals for details. Note: When running SETUP30, you don't need to use the "Copy Files" command because the files are already installed on your hard disk.

Instructions -- To Upgrade

Here is how to upgrade to version 4.00K, if you have an existing installation of the Adapter Independent Invisible LAN Operating System, for DOS and Windows 3.X.

1. Click here to download ILAI.ZIP (1666K).
     
2. Unzip ILAI.ZIP directly into your existing NET30 disk directory. (The NET30 directory is the directory where the Invisible LAN operating system is installed.) For example, with PKUNZIP you could use the following command:
   
       PKUNZIP  -d  ILAI  C:\NET30\
   
   Notice the -d parameter. This tells PKUNZIP to use the subdirectory information in the ZIP file.

When you unzip ILAI.ZIP, the version 4.00K files overwrite your existing Invisible LAN files. Your existing network settings and security system are preserved through the upgrade.

Note: If you are running Ultra Server, you should also download and install version 4.00K of Ultra Server.

Note: Upgrading only works if your existing Invisible LAN is version 3.00 or later. If you have a version prior to 3.00, you need to delete your old Invisible LAN software and perform a new installation of version 4.00K.

Instructions -- To Convert from AD to AI

If you replace an Invisible Software network board with a network board manufactured by someone else, then you need to convert your existing Adapter Dependent software to Adapter Independent software. These instructions tell you how to perform the conversion.

1. Click here to download ILAI.ZIP (1666K).
     
2. Unzip ILAI.ZIP directly into your existing NET30 disk directory. (The NET30 directory is the directory where the Invisible LAN operating system is installed.) For example, with PKUNZIP you could use the following command:
   
       PKUNZIP  -d  ILAI  C:\NET30\
   
   Notice the -d parameter. This tells PKUNZIP to use the subdirectory information in the ZIP file.
   
   When you unzip ILAI.ZIP, the version 4.00K files overwrite your existing Invisible LAN files. Your existing network settings and security system are preserved.
     
3. Delete the file NETAD.OPT from your existing NET30 disk directory. This deactivates your existing Adapter Dependent software. The following command is an example of how to delete the file.
   
       DEL  C:\NET30\NETAD.OPT
    
4. Run SETUP30 (the Invisible LAN setup program), and select the appropriate network hardware type.

Note: If you are running Ultra Server, you should also download and install version 4.00K of Ultra Server.

Note: This procedure only works if your existing Invisible LAN software is version 3.00 or later. If you have a version prior to 3.00, you need to delete your old Invisible LAN software and perform a new installation of version 4.00K.
