[Guide] HackrNVMeFamily co-existence with IONVMeFamily using class-code spoof

[RehabMan]

ok i will look that up when i come home but for now is it possible to use windows 10 to go on usb and check the ACPI path? or windows must be installed in order to get the correct info...
can vmware workstation that have windows 10 in it get that info as well btw? i have 10.13.3 on my 960 evo m.2 installed already.
should i buy a 32gb usb drive or is that just waste of time and money since windows to go will not help me after all...?

No idea what you mean by "windows 10 to go on usb".
VMware not applicable.
This guide does not apply to 10.13.x.

However you decide to run Windows is ok, as long as it is on bare metal and not within a VM host.

okej so if i try to use windows 8.1 that is installed on another ssd is that possible to see the 960 evo or does it only work from windows 10 ?

Edit:
btw is it safe to upload my .iorg file here ? or is that a security risk for me since it shows all my hardrive serial numbers etc.
i really cant make this work and have no choice but to upload the file and hopefully you could find the correct path and tell me so i can move on already and go to the next stage in the kext making

I have never used Win81 for this purpose.
You could always try it and see what is displayed in Device Manager.

It is done quite often here.
Your call.

NVMe SSD is here:

The device is at a path without a full ACPI identity. Partial path is _SB.PCI0.NPE7.
As per post #1..., the full ACPI name needs to be added, and since this is 10.11 and a804, additional properties are needed to spoof as a801.

All you need as far as creating SSDT_NVMe-Pcc.aml is in post #1172.
Other details (generating HackrNVMe kext) is in post #1.
