- Boy, there sure is a lot of confusion over what NetBIOS is. Quoting from
- "C Programmer's Guide to NetBIOS" by W. David Schwaderer (Howard W. Sams
- Publisher) without permission, "The Network Basic Input/Output System
- (NetBIOS) is an application programming interface for data exchange between
- data sources and data sinks. Loosely speaking, NetBIOS is a programming
- gateway to sets of services that allow computer applications and devices
- to communicate."
-
- All together now... NETBIOS IS AN APPLICATION PROGRAMMING INTERFACE.
-
- One uses NetBIOS by setting registers and invoking software interrupt 5Ch
- on an Intel 80x86 architecture machine. Period. There is no standard
- NetBIOS packet to be "encapsulated" into different protocols. The NetBIOS
- standard as it currently exists does not specify the actual network protocol
- to use on the wire. There are lots of different implementations of the
- NetBIOS interface that use different protocols on the wire including
- TCP/IP, OSI, DECnet, IPX/SPX, XNS, NBP, NetBEUI, and probably lots
- of others I forgot about. There is no "trickery" involved in using IP
- as the transport for NetBIOS. You just buy and use a NetBIOS which
- uses TCP/IP. These can be had from FTP Software, Microsoft, and 3Com
- among others.
