I have found the solution myself, i forgot "-DIMAGE_FREEBSD", in fact i thought i set it at my 2nd try, but on the 2nd try, i had the floppy write protected, which i didn't notice.. :-( Now the kernel gets loaded, last output from etherboot is "........done" and then the system reboots.. :-( Heinrich > > Thanks for any hints > > Heinrich > > > ------------------------------------------------------------------------ > > # > # Config for Etherboot/32 > # > # Do not delete the tag OptionDescription and /OptionDescription > # It is used to automatically generate the documentation. > # > # <OptionDescription> > # User interaction options: > # > # -DASK_BOOT=n > # Ask "Boot from Network or from Local?
