You appear to have misinterpreted my sentence.  When I say, for example,
"Win95 supports NetBIOS", I mean that it supports the NetBIOS API and
framework over one or more transports.  It so happens that Win95
supports NetBIOS over TCP (NBT), NetBIOS directly on ethernet (NetBEUI),
and NetBIOS over IPX.  Its SMB code works with all of those, though
running more than one at once creates nasty problems with browsing that
are best resolved by picking one and dropping the rest.  Samba servers
are accessible from a Win95 box if and only if you have NetBIOS over TCP
enabled on the Win95 box.

I don't know why you would _want_ to install NetBEUI.  As for unbinding
NetBIOS from TCP, I'll say again that, to the best of my knowledge, you
cannot currently access a Samba server without using NetBIOS over TCP.

Exactly.  The TCPBEUI driver implements NetBIOS over TCP, not NetBEUI.
