This really depends on your network. TCPBEUI is NETBEUI, packaged
within TCP/IP packets. TCP/IP is routable, while NETBEUI is not. As
soon as you want to connect to a machine that isn't reachable with a
broadcast (for instance because it's behind a router), NETBEUI won't
get you there. However, because of the overhead of TCP/IP, TCPBEUI is
a fraction slower than NETBEUI.

MPTS should be able to show it. Or, you can have a look at
protocol.ini. The interesting parts from my protocol.ini:

[NETBIOS]
   DriverName = netbios$
   ADAPTER1 = netbeui$,1
   ADAPTER0 = tcpbeui$,0

[netbeui_nif]
   DriverName = netbeui$
   Bindings = ,E100BEO2_nif

[tcpbeui_nif]
   DriverName = tcpbeui$
   Bindings = W168CX1014_nif

[tcpip_nif]
   DriverName = TCPIP$
   Bindings = W168CX1014_nif,E100BEO2_nif

>From this, you can tell that:
- TCP/IP is bound to both adapters
- TCPBEUI is bound to the genmac driver (for an Atheros card) (as number 0)
- NETBEUI is bound to an ethernet driver (as number 1)

Then, over to the interesting part of ibmlan.ini:

[networks]
  net1 = TCPBEUI$,0,LM10,34,100,14
  net2 = NETBEUI$,1,LM10,34,100,14

net1 uses TCPBEUI, on number 0
net2 uses NETBEUI, on number 1

(further down in ibmlan.ini, I have wrknets and srvnets set to net1,net2)

Btw: with the setup above, Peer works over my genmac driver.
