Windows 2000 and XP Support Information

In order to install Interpex DOS based software under Windows 2000 and Windows XP, certain criteria must be met. 

1. The package you are trying to install must be able to run under Windows 2000 and XP.

2. The copy protection system your package is protected must be compatible with Windows 2000 and XP.

3. You must be running the correct version of Windows Windows 2000 and XP.

4. You need to establish a shortcut to install the package. The default MS-DOS prompt in Windows 2000 and XP will not work due to the way it allocates memory. 

1. Software Compatibility 

The following is a list of software packages that will successfully run under Windows 2000 and XP

Resix v3.x
Resix Plus v2.x
Resix IP v2.x
Resix 2DI v1.x & v4.x
Resix IP2DI v2.x, v3.x & v4.x
Emix 34 Plus v3.x
Emix MM Plus v3.x
Emix MT v2.x
Emix MT2D v3.x & v4.x
Emix VLF v1.x
Temix v4.x
Temix XL v4.x
Magix Plus v3.x
Magix XL v3.x
Firstpix v4.x
Gremix, Gremix 15, Gremix 15S, Gremix S v2.x

None of the Gradix or Seistrix version will work under Windows 2000 or XP. This is due to the specific implementation of protected mode technology and/or Vesa graphics in these programs. 

2. Copy Protection Compatibility

Once you have established that the program that you are planning to run under Windows 2000 and XP, is capable of doing so, you need to make sure your program is protected using a HARDWARE KEY. Program protected with Software keys will NOT run under Windows Windows 2000 and XP.

In most cases a replacement program can be obtained for a minimal cost, however if your program is not the current selling version you might be required to update to the latest version. 

In addition to being protected with a hardware key, you are required to install a Windows 2000 and XP driver for the hardware key. They driver can be found at:

Download this driver and install on your computer.

3. Creating the Windows 2000 or XP shortcut

If you try to use the standard COMMAND PROMPT under Windows 2000 or XP,  the installation of some of the Interpex programs will fail. The standard command prompt under Windows NT only assigns 1 MB of extended memory. The Interpex installation program checks for available memory and will not install the program if the memory is not available. 

To overcome this limitation of the COMMAND PROMPT, you need to establish a shortcut that will assign more memory. Detail on how to do this can be found in the following PDF document. This document is specific to Windows NT, but the procedure is the same for Windows 2000 and XP.

4. Run the UserPort program supplied from AZ-TECH.

The driver downloaded above and installed includes the UserPort kernel mode driver, written   by Tomas Franzon.  This driver allows 16-bit programs running under Win2K/XP to have usermode access to the I/O ports, just like in Windows 95/98/ME.

Please note that the UserPort driver is only required for iButton  access by 16-bit programs running under Win2K or WinXP.  It is not required by any other version of Windows.  Also, Rockeys and 32-bit programs do not require UserPort.

UserPort must be manually started once and will thereafter start automatically each time Windows is booted.   Of course, you can manually stop UserPort at any time.

    To START UserPort:

1. Be sure that the Az-Tech Device Drivers have been installed.
2. Be sure you're running on a Windows 2000 or Windows XP system.
3. Click "Run" on the Windows "Start" menu.
4. Enter "userport" and click "OK".
5. Click the "Start" and "Exit" buttons on the UserPort dialog.

    To STOP UserPort:

1. Click "Run" on the Windows "Start" menu.
2. Enter "userport" and click "OK".
3. Click the "Stop" and "Exit" buttons on the UserPort dialog.

5. Execute the program as per your User's Manual.
