[Samba] MSDOS on my network

[Alex]

Hello,
I am looking for the first time at setting up Linux with Samba as a primary 
server on our network. I would like to replace my SCO Unix system and a 
Windows box I use to serve MSDOS machines. The MSDOS server seems to be the 
stumbling block at this point in my research. I can only run netbEUI on 
them as far as I know and Samba seems to only talk on TCP/IP. Do you know 
of a solution?
Thanks for any help,
Alex Janssen
