Which architecture, which board?

What exactly is the problem with this? It's what I would expect... If
you want to  automatically  switch  to  NC  as  soon  as  it  becomes
available you can always do this using some CONFIG_PREBOOT settings.

What does your overwrite_console() look like?

And  what  exactly  are  you  trying  to  do  here?  What  does  your
environment settings look like?

What do you mean by "bootup"? NC will or course only work  after  the
main  intitialization  sequence  has  been  completed,  i.  e.  after
relocation to RAM, and after ethernet and devices initialization.

The software required `Windows 95 or better', so I installed Linux.
