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. https://en.wikipedia.org/wiki/NetWare https://en.wikipedia.org/wiki/NetWare It came out in 1983 so it supported MS-DOS versions earlier than 3.0 apparently? 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. 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/Linux to survive as it lost Netware licensing as Windows NT took over.
