I have used NetMinder to get the packet information but I haven't had 
time to look at them yet. I have packets from a ROM 3 booting off of an 
AppleShare 3.0.1 server and packets from a ROM 3 trying to boot off of 
an AppleShare 2.x server (the "fizzy" code looks like it comes in one 
ATP packet from the 3.0.1 server but comes in many packets from 2.x). 

Anyway, I am not able to get the ROM 3 to boot successfully off of the 
2.x server and I haven't had time to swap a ROM 01 motherboard in to get 
a packet trace from a ROM 01 boot off either server.

I could post the packet traces if someone wants to look at them (it 
looks like I won't have time until around Thanksgiving or Christmas 
before I'll be able to get to them, especially with spring here and the 
yard exploding from the mild winter this year).
