You're doing it the wrong way.  A .iso file is something to burn to a CD; it's 
not a native file format.  You need to mount the .iso and copy fhe contents to 
the flash disk.  I'm not certain how you would need to format the flash disk, 
though I suspect that NetBSD format is correct.  You'll also have to make sure 
there's a boot sector and a disk label.

I think there's more, but I'm not certain what it would be.
