Okay I just got it running on a win2k machine. I used the same download, only I renamed the warpl~2.exe. (I think...it is the 673K file) You can open it in winzip and see the files are 26 aug 2000, the ~1 files are the exact same age and size as on the CD.
After I installed, and once I added the new LAN connection (in properties) I had to install the packet.ini as a protocol for the warplink.
I already had a LAN with a regular nic (with ICS) so I had to disable that one (for now) and make the warplink 192.168.0.1 (for ICS).
After a couple of reboots to reset the warplink card to the new Ip address, it works, and I am doing this on the Iopener (98SE machine) with ICS through a win2k machine.
Only weird part...and probably due to my win2k install...I have to disconnect the warplink card for boot up otherwise win2k reboots at the setting network connections part of the boot.
Okay weird part #2. For ICS you set up the modem (in my case) for sharing. Well it wouldn't let me share to the new lan connection, so I had to make a new internet connection, exactly like the first. When I went to sharing on that connection, it now showed both LAN connections and gave me a choice for sharing.
Of course what that means is either the Warplink lan gets the internet or the regular lan, but not both.
I will probably have to play with server to get both to work (nat).
