On the one machine that went through (because it got the IP first) I got the output from dmesg, printed it and compared it to the both boot screens. And they are really identical. I didn't see any option (or "extension") that contains the mac address. Could that be the problem? Do I have to tell the server that the mac address must be in the request-list? cu, Frank IP-Config: Entered.
