Is more memory ignored or does it hurt operation?

I have my issues here, though I do not know if ppc related or DHCP/TFTP.

The target is a Dual 1.8Ghz G5, 2.5GB Memory.

The build host is an i386 which eports the installation on
/exports/netboot/ppc64

The tftpboot directory contains the loader.ppc64

The dhcpd.conf looks like this:

host bohrium {
      hardware ethernet 00:0a:95:bf:0f:de;
      fixed-address bohrium.andreas.nets;
      next-server 192.168.225.35;
      filename "loader.ppc64";
      option root-path "192.168.225.35:/export/netboot/ppc64";
  }

I can issue the of boot command and I see that I can download the 
loader.ppc64. It 'starts' with my build machines name etc.

But then I get repeated messages like below:

xmt1 timeout , STAT=00002086, Txlist.status=efbeadde:efbeadde

a lot of lines after it says 'bootp: no reply'
and 'panic: arp: no response for 0.0.0.0'

I had to manually type that down....

Any idea? Is my tftp/dhcp crap? Or is my G5 not ready yet ;)

TIA,

Andreas
