Which version of the ROM monitor are you using?  The old one couldn't download
over the 100 Mbps port, so we had to connect both.  We used the 10 Mbps port
to download the kernel, and the 100 Mbps port once the kernel comes up.  Of
course, you need a 10/100 switch to do this.  I believe that Embedded
Planet are working on a new ROM monitor, which hopefully will correct this
problem; I don't know if they're shipping it with production boards yet
though.

Note that there is a hack in the fec driver which munges the ethernet MAC
address for the FEC port by adding 80:00:00 to the number that the monitor
reports on the CPM port.  You'll need to configure your dhcp & nfs server to
recognise the board via the munged address.  Your tftp server on the other
hand needs to recognise the unmunged address.

You're using the unmunged address here, where it should be 00:10:EC:80:00:00.
This is probably why your bootp server doesn't respond.  By the way, they
didn't _really_ sell you a board with a MAC address ending in all-zero, did
they?

Once you've got it set up, your arp scripts will be unnecessary.
