NetBIOS != NetBEUI.  NetBEUI is a non-routable protocol implemented
directly on top of ethernet; NetBIOS refers to that payload in general,
which has been implemented on top of other protocols, including TCP/IP.
Ports 139/tcp, 138/udp, and 137/udp are netbios endpoints on MS
machines.

To make matters more confusing, the standard payload of NetBIOS is SMB
(aka CIFS), which now has its own tcp port in Win2K and later
implementations (port 445).  NetBIOS is still supported, however, for
compatibility with pre-Win2K clients.

The only Microsoft OS I'm aware of that didn't support NetBIOS by
default was Win98 OSR2, which required you to install (but did not
require you to enable) the NetBEUI protocol driver in order to get
support for file/printer sharing.
