[DEPRECATED] ASRock Rack EP2C602 Install Guide for Sierra and High Sierra

[teamawesome]

Your mobo EP2C602 has crappy UEFI support - latest offical 1.80 12/24/2013. My have latest offical 1.80 3/23/2016.

This is why we can't have nice things.

That I can say is what ASucks firmware verification process is broken as f...ck.

How about -xcpm boot option!

Removed, and also you'd use -xcpm_ipi since it's multi-cpu.

And yes, this board has the jankiest bios UEFI implementation I've ever come across.

Correct, you would have to use -xcpm_ipi... if it still existed.

• Does Sleep and Power Nap works?

I have been running renderings and encodings so much I haven't checked. I haven't really had a moment yet where the system was idle to sleep.

Have you tested? Don't forget https://tonymacx86.com/posts/1695886

@meltman, does Sleep and Power Nap works on your Asrock EP2C602 system?

@meltman, does Sleep and Power Nap works on your Asrock EP2C602 system?

No, neither work. I've not spent much time trying to make it work but I'm not super encouraged by initial results.

In my past builds the systems would usually sleep when instructed to. I've been unable to get MacOS to sleep this build at all thus far.
