In case I didn't understand properly: what do you want to do, now? You said
you wanted to speed-test your machine long and in real mode.

You seem to have done the test under Linux already. You were in long mode
when running Linux. Why do you want to go to long mode manually then?

What's left is real mode and there are quite few things easier than running
some code in real mode.

If there's a specific reason, indeed, to go to long mode by hand, you may
also use Pure64[0] to boot into your long mode and execute code then.
