I did sent a BRK to the serial port and that drops us into the firmware
"ok" prompt. There is a failed fan but in fact the fan is entirely not
there. At all. I removed it because it had failed five or six years ago
and getting another one is just annoying. Also it is not really needed.
Is the heatsink on the board cooled by a chassis then?
We can see that there is 1G of ECC memory and the memory passes all the
basic tests.
Now I setup a few of the firmware variables and reset the unit :
ok printenv
Variable Name Value Default Value
[...]
local-mac-address? false false

However there must be a bug somewhere because the physical MAC address
is the same on both interfaces.
This is due to `local-mac-address?` set to `false` in OBP. See e.g. [1]
for details.
