I just bought an iBook and I am trying to netboot NetBSD on it.
It loads the ofwboot.xcf via tftp, but then it fails.

I do:
0 > boot net:0,ofwboot.xcf netbsd

The dhcp, tftp and nfs daemon are on the same NetBSD i386 machine.
This is my /etc/dhcpd.conf:

This is the network traffic after the tftp:

I do NOT see network traffic that indicates that the
"/export/clients/spock/root" information is sent to the iBook.

Any suggestions?

PS I have experience with netbooting NetBSD. I can successfully netboot
a SPARCstation 1 and pxebooting a Soekris net4501.
