I hopefully solved the problem with this error message: it's not a bug
in the netboot NDIS interface but in the Xircom NDIS driver. It does
not report it's upper layer interface correctly to the bootrom. Actually,
there is just one byte wrong in the Xircom driver image, which is at
offset 0x05A0 of cbendis.exe and reads 0x00 but should read 0x01. You can 
use a binary editor to change this byte, and then it should work. However, 
I wrote a workaround for netboot, which will appear in the next release.

Please note that I'm unable to test this myself due to missing hardware.
