3 I believe you should check and make sure you have the "Enterprise"
version. If OpenServer is the "Host" version don't bother trying to
get a NIC working. There are still many "host" systems around using
nothing but serial terminals. Others would know the best way of
determing your version. i check it in scoadmin -> licensing .

(IMHO This has to be one of SCO's classic dumb moves to consider
TCP/IP a chargeable option !)
