UDMA-Driver for 3.12

Hello,
I tried the information on
http://www.huweb.hu/maques/nwudma.htm
and find it interesting.
I tested it on my 3.12 server and nearly all things seem to work fine,
but during startup the message came: NEB.NLM cannot be loaded by STARTUP.NCF
Does Anybody know, wether it is a serious problem or not? The system is
running...
with kind regards,
Gerd Steffens
