Ahhh...  The chip manufacturer does distribute a reference/example
copy of firmware, and the firmware is actually microcoded and supplied
from the OS.  The NCR driver code/microcode source is normally
distributed along with the driver.  You can compile it yourself.
In that regard, it is similar to the Adaptec 78XX drivers.

I would suspect that the microcode source is in the NetBSD source
tree in ncr.c (it is embedded into a C struct/array.)
