 As I said in my original report, I needed to have a functioning system
 on the machine in question, so I've installed a Linux distribution and
 therefore cannot check exactly what was in /libdata/firmware. I did
 mention previously that there was a file, perhaps a directory, in that
 firmware directory and it certainly had the string 'iwn' in its name.
 It may well have been if_iwn.
 I did a pretty vanilla install of NetBSD 7.1 on this machine. I did
 elect to customize the sets, eliminating games and tests from the
 defaults and adding some things, too, e.g., documentation. So I think
 it's reasonable to assume that I had the same firmware files you do,
 if they are a standard part of the installation, as they appear to be,
 despite the confusion about whether firmware gets installed by default
 or via a package. But after setting up the wifi device (I did the
 install using the ethernet port), the boot-time attempts to load the
 firmware always failed, as I reported and the wifi device was not
 functioning (I tried to ping my gateway).
 I do have a spare 320GB USB drive and thought I'd try redo-ing the
 install to that drive. But with the drive plugged in when booting the
 installer system, there does not appear to be a way to choose that
 drive as the target. The only choice I get is the internal disk.
