I worked with Novell Netware when it had 68000 based servers. I forgot what DOS version we used but the Novell Netware software hooked the DOS Interrupt 21H to provide network drives.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;NetWare" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;NetWare</a><p>It came out in 1983 so it supported MS-DOS versions earlier than 3.0 apparently?<p>I remember working with Starnet cards that basically used what looked like 9 pin serial cables. Then Arcnet came out that use Coax cables, and we used Thomas Conrad cards for faster access with Arcnet. I remember the computer lab floor was made out of panels you could remove with a twin suction cup device to access the network cables. We had to install Arcnet hubs under the tables the IBM PC systems were on.<p>Novell Netware was phased out when Microsoft made Windows for Workgroups and had built in file and printer sharing and released Windows NT 3.1 Server with SMB sharing. I think before that used LanManager for DOS sharing. Novell had to get into GNU&#x2F;Linux to survive as it lost Netware licensing as Windows NT took over.
