| The rc.d script iterates "cpuctl ucode 0" through "cpu ucode hw.ncpu-1" | but the man page says that the option after "ucode" is the filename. Read it again, more carefully.
It just occurred to me that all of my x86 machines are running netbsd-7 because netbsd-8 isn't quite stable yet for x86, so I didn't see the updated man page. Good to know that's fixed.
I sent a message to AMD about amd64.org, which still is owned by them and which still points to their netblock. We'll see if the site has a future.
