That was my first assumption. I hit F5 because that' sends a break and 
it didn't. Hence my confusion. I probably missed something.

Either that or I am forgetting something about UltraSPARC II era 
hardware? I yanked the hard drives while I test it ant it's trying to 
netboot (it'll struggle!) So it's stuck in a timeout loop. From my 
memory Stop-A/BREAK drops it out of the loop to the OBP?

Re-educate me with heavy wooden objects if I'm wrong there by all means :)
