# rpm -q dhcp
dhcp-3.0.5-5.el5

I think that is what I have set 'filename' option to be...only yaboot
but that file and TFTP never worked for the Macs unless yaboot and
associated files were located in tftp root - nowhere else (I could be
wrong on this but that is what I found)

where's 'next server' setting?

boot the iBook with <Apple><Option><O><F> and typing...(not that I'm
sure that this will make a difference).

boot enet:192.168.0.254
