Where is yaboot.conf

[Stephen Allen]

Hello,

I'm trying to boot an Xserve G5 into Linux over the network.  After 
spending ages messing with DHCP I am now at the stage where the client 
receives an IP address and boot filename (yaboot), and duly goes off to 
fetch it using tftp.

However, when yaboot executes it is giving the message:

     method 'load' failed fffffefc
     Error, can't read config file
     Welcome to yaboot version 1.3.13
     Enter "help" to get some basic usage information
     boot:

The version of yaboot I'm using is 1.3.13a-ubuntu5 and I at ve tried 
binaries from both the Debian and Ubuntu respositories.

The contents of [tftproot] are:

     boot.msg
     initrd.gz
     mini.iso
     vmlinux
     vmlinuz-chrp.initrd
     yaboot
     yaboot.conf

So I gues the question is, how does the yaboot binary know where to 
fetch yaboot.conf from?  Or, where is it expecting it to be when booting 
from the network?

I hope someone can help as I'm completely out of ideas.

Kind regards,
Stephen Allen
