Moving HD with DomainOS on HP 400t

[supervinx]

I need to move an HD with DomainOS, from an HP 400t to another.
The HD is tied to NID 404DA.
Well, I thought the easiest way was to set the same NID in the receiving
400t but ...
MD menu is different from the DN3500.
The ConFig (CF) menu lacks node id setting.
I tried NID new_nodeid_number, getting WRITE PROTECT error.
So I begin to think that the physical NID is unmodifiable on the 400t.
Do you know if it's stored in a DIP chip and this is located near the DIO II
bus connector ?
If it is so, I'll swap the two chips... I don't want to use chuvol ...

Well ... the nodeid is stored in the EEPROM, so I must remove it and put in
the other 400, according to the service manual a1630-90007.pdf

Done, thanks !
The whole job has been a bit tricky, since after replacing the id chip and
stored the HD containing Apollo DomainOS, I put a 1050 MB HD,
containing a 1.0 GB HP-UX 9 image, for a friend (source and dest disk
were different).
I had to change boot mode and keyboard, from Domain to HP-UX (it seems
that the KB must be changed with SK only from the Domain side ...) and
hope that HP-UX will like the different HD.
All went well, and HP-UX booted happily.
Now I'll install the old id chip and HD on an empty 400 (with a 68030, the
68040 has gone to the friend ...).
