Hi,

I'm looking at external IDE disk serving as NAS.
Many of them advertise using Linux and seem to be able to upgrade the PROM.

My question is, what is the generic procedure to replace the embedded Linux with a home-made NetBSD kernel/userland ? Is this difficult ? I mean is there a need of finding a hole in the software update process or is it as simple as "replacing the firware image" with a bootable iso file ?

TIA,
   Jo
