My wired keyboard is starting to flake out and I'm not able to PRAM reset the machine at boot with the Option ⌥ + Command ⌘ + P + R sequence. I tried plugging in a Windows keyboard and use Alt + Windows key + P + R , but the Mac doesn't seem to recognize the sequence.
Is there a command line equivalent to the keyboard boot sequence above? I tried
sudo nvram -c but that didn't seem to do it.
The idea is that I want to set the boot volume to something else, but I'm flying blind on a MacPro3,1 since the video card is a non-EFI PC one so I can't just do the "hold option at boot" trick.
