So we see that the value "09" was modified by the value:mask "00:01" and became the value "08". Adding the "-v" flag produces verbose output: Here, I set the least-significant bit to zero. Instead of clearing the entire register by setting the value to zero, one can set arbitrary bits using the value:mask feature of setpci. So I made one tweak to the invocation of setpci. I don't know what bit three does but I'd rather not find out the hard way :-). Here we see that it was "09", which is binary 1001. This worked for me on a Mac Mini 6,2 using method 2: I used Ubuntu 14.04 on a DVD to run setpci.īefore making the change I checked the existing value: Once that has been enabled, you can then perform your ESXi installation.

If you already have OS X install on your Mac Mini, then you just need open up the System Preferences and enable auto startup under the Energy Saver section. I have turned off the computer several times, but when it opens the line going across only goes part of the way and then it opens. YMMV depending on your hardware and/or firmware. I am using Sierra and had been working with photos and burning DVDs when the desktop suddenly changed its appearance. Note: I have heard that historically the auto startup flag has not persisted in older Apple hardware, but for the new Mac Mini 5,3 and 6,2, they seem to be persisting without any issue from my testing. I finally got a chance to look into this a bit more for myself and with a bit of research, I found several other methods which also works and may potentially be easier. Several folks from the VMTN community such as zippytiff and twuhabro have already confirmed having success using the latter option when booting OS X off a USB or SD card to modify the energy saving settings. Normally to enable this feature you can either run a setpci command on UNIX/Linux system or configure the energy saver settings in OS X.

The challenge arises when you are running ESXi, how do you go about enabling this functionality in ESXi itself? Well the answer is actually quite simple, you can enable this outside of ESXi. Automatically starting up after a power failure is not a new feature of the Mac Mini and it actually exists on most modern day systems and can be configured using a variety of tools. This is extremely useful for situations where power is eventually restored and you are not physically around to press the power button.

I recently came across a very useful tidbit after receiving several inquires asking how to configure an Apple Mac Mini to automatically startup after a power failure.
