Forcing network speed and duplex in Open Boot prompt

I had a Sun box attached to a switch I had not control over and I needed to jumpstart it. Unfortunately, I was getting nowhere. After crosschecking everything in my setup the only thing I did not try was to force speed and duplex on the Sun box to see if it would start booting. [...]
