You are right. I was wrong. Thanks for your answer. Sorry for wasting 
your time.

I verified it so far with a Vmware partition (two nics, floppy, cdrom, 
disk) and in all combinations of boot order  (first NIC first, the rest 
variable) and localbot does the right thing (goes either to floppy, 
disk, cdrom or second NIC).

I will recheck what is the problem with problematic nodes that failed 
previously.
