Hi zizan
So, you unzipped the package into \ibmcom\macs, ran MPTS to add the card and required protocols and rebooted.
Did you see any message regarding the driver loading during boot? - create an empty text file called ALTF2ON.$$$ in the root of the boot drive or, if you are quick, press ALT-F2 when the system displays OS/2 (or eCS) in the top left of screen as boot starts. I find the file method works nest for me as I always seem to mistime when to press the key combination.
As mentioned previously I have no experience of using this type of nic so no idea on an extra setup steps required. Hopefully someone will have some ideas either here or in the os2 newsgroups - might be an idea to search these forums as the answer could well have been posted in the past.
Regards
Pete
