| Each form returns "cpuctl: -1: No such file or directory"
The hint for the problem is the "-1" in that message. It
turns out that cpuctl doesn't actually like you giving -1
for the processor number, and you don't need to, that is the
default. (Any other number, except -1 is acceptable).
That's why it can't find the file, it is looking for something
literally called "-1".
Just leave that out, and try again. Generally for an AMD processor
when the microcode is stored in the (a) correct place, just
cpuctl [-v] ucode
should be enough. I'd suggest including the -v when you run
it manually (but not when it is in a script run by rc.d or similar,
once the correct format works)
