Cause something looked so strange, I looked at the DHCP-Server (OpenSuse
10.3, running DHCP, TFTP, Apache2) to see at the log-files created by
this DHCP Server. Usually, I give IPs depending on the MAC.
Windows told it, using the "ipconfig -all" command. Same then with knoppix
Last and this is now my only reference to it, cause if checked that so
often: The PXE-Boot of the BIOS tells it at boottime during the first
screen, after PXE-Boot is up and before the PXE-Boot-menu comes up.

Yes, using any life CD like systools, knoppix, ...
didn't ry this one.

Yes, this was my first sight to get an Idea, what was so strange (really,
I never thought to have Problems with a MAC)
I'm ready to use any additionally tool...

Good way! This is what I allmost going to try. But now, my different
angles are gone :-( So any input is welcome!
