Well, BOOTP is the predecessor of DHCP, so if you specify that, that
means automatic address retrieval. If it works the same way as in SLOF,
you simply have to omit the "bootp,":

 load net:10.61.2.7,takeover.elf,10.61.254.21

I think I've seen this once or twice on the PowerStation, too, ... IIRC
it went away after rebooting. Not sure what the problem here is...
