Ok, I added: "always-broadcast on;" to my dchpd.conf.

Now, this is the tcpdump (client still does not set the IP):

To me, this looks good.
Could it be that there is a problem with the linux kernel to load?
The path is good (/tftpbook//lts/vmlinuz-2.6.17.8-ltsp-1)...

I do not understand why windows does that and it wont work with the 
boort rom...

Thanks for the help again, but I really would love to get this done...

Do you have another idea?

Best regards
