Um... by "firmware" one usually understands the kind of software stored
into a system's ROM or so, which is responsible for the very early steps
of the boot process, e.g. on a PC to read the MBR etc.
You do not update that from NetBSD - there are usually boot disks from the
PC/hardware vendor to do so, and there's not much help the (any) operating
system can do in that process, I'm afraid. At least NetBSD doesn't provide
anything as far as I know.
If you mean just replacing a few files like kernel and other funstuff on a
local filesystem (CF card, whatever), that's different.
But I'm not sure what exactly you mean here.
