Hi hamada,

The most foolproof way (and the way I have had the most success with) is to:

  • Load MPTS and select the NIC card in the bottom list. Change it to "No network adapter" by selecting "No network adapter" in the top list, exit (and save) out of MPTS.
  • Restart the machine (or if the new NIC isnt in it, shut down OS/2 normally, install new NIC and restart).
  • Load MPTS again, change "No network adapter" in the bottom list to the new NIC card driver, exit and save, and restart.

* If the new NIC card driver is not on the list, you can copy it into the IBMCOM/MACS directory before step 3 above.

This method is the method I have found to be least likely to corrupt the ini files... as I have had happen on occassion when removing the network card and it's associated network bindings from MPTS.

If you need more detailed explanations, let me know, and I can post screen shots and more detailed instructions...

Well, seeing that you have received no replies to your basic question, I want to welcome you to the OS/2 World!  Below is the bare scheme of what is to be done:

At your OS/2 window command prompt, type:


click yes, if needed, to the IBM informational dialog and you will be offered the following dialog

If you will be installing a NIC driver, then select the button labeled Install, and you will be subsequently  presented with another dialog prompting you to specify the path of the Nework Information Files (.NIF).  Simply provide the path to where those are and select OK; the utility will install your NIF --make sure to note down the name of the driver reported by the utility when it successfully completes.

If you will be configuring (i.e., removing and/or adding Network card NIFs and/or Nework protocols, select Configure button, of course.  You will be presented with an additional dialog like this

Select Configure once more and you will be presented with the next screen.  Looking straight at the screen, on the upper left corner you have the available Network card NIFs; on the upper right corner will be the available protocols that you can install after you have successfully installed a Network card NIF, of course.

Finally on the bottom window, you will see your current configuration for your Network card NIF and the associated protocols.  Make a note of the existing protocols, specially if your current setup was working fine.

To remove an existing NIF and Protocol association (from the window below) that will effectively remove them from your OS/2 configuration files (after you reboot), you must first remove the protocol before attempting to remove the NIF; else you will see the following error

To install another Network adapter NIF, you select it from the available ones in your upper left window (a 3Com in this example) and select the button Add.  You will see the NIF added to your bottom window.  It wil be ready to accept a protocol from the upper right window:

Now, from the upper right window, select (one of) the protocol(s) that you want to associate with this NIF, say IBM TCP/IP implementation. Once you select the Add button your selected protocol will appear under your highlighted NIF (3Com in this case).

Save your changes by selecting the Ok button on the right and subsequently Exit and agree to have your OS/2 CONFIG.SYS modified (you may decide to make a back up copy first by pressing CTRL-ESC and selecting to open another OS/2 command prompt before the modification takes place).

After you are done with your task, you may want to write a short how-to article, blog, wikki, etc., and post it here (or somewhere else) to help others who will come across a similar issue  ;)

P.S. Moderator, you posted before I finished this.

Is the 'Change' button in MPTS on Warp3 not available? On Warp4 and up there's no more to do than select the installed current driver in MPTS, select the new one in the other window and press change. Exit and reboot and you're done.
