To change CONF-82, which switches the AMIGO ID from that of a 7980A to
that of a 7978B, perform the following steps:

       1.  Select CONF 100 and set it to 48
       2.  Select CONF 101 and set it to 76
       3.  Select CONF 40 and set it to "ON"
	    (keeps change in NVRAM)
       4.  Select CONF 82 and set it to "HP7978"

I hope this works for you. I also found out that you might need rev 5.13
of segment 41, the 7984 driver in the OS boot area.

Regards,

Joseph
