Protocol Manager: Invalid function

[Matthias Meyer <M.Meyer@maxonline.at>]

Hello,

Because I have no success with the packet-driver for my PCMCIA Xircom-nic I 
try the NDIS-Driver.

After makerom (installed from netboot-0.9.1-87.rpm) I boot my laptop from 
this floppy.
following appears:
-----------------------------------------------
Netboot disk loader
Netboot V0.9, Copyright (C) 1995-2000 G. Kuhlmann

Xircom CardBus Ethernet 10/100 Adapter NDIS v3.14 (010129)
Copyrigth (C) Xircom, Inc. 1996-2000 All rights reserved.

Memory Address CC000, IRQ 11, Node Address 0010A4051111


Protocol Manager: Invalid function
Press any key to continue...
-----------------------------------------------

I use the cbendis.exe and protocol.ini from the Xircom DOS Install Disk.

What the reason for the message?
Anybody can help me?

With thanks in advance
