Hi, just like the title states I need help understanding there relationship, if any?

 

I want to install 10.12 with Clover_v2.3k_r3859 in the EFI partition. On my last install, 10.10, I did not take notes on how I got it to work on my laptop. 

So I now have to redo the legwork. 

 

I'v been installing OS X on PC's since 10.7. so I'm not a total noob. 

 

Q: What is the difference between bootx64.efi and cloverX64.efi? 

 

Q: I've installed Clover_v2.3k_r3859 but it no longer installes boot0. 

All I see are boot0af boot0ss. Is this what replaces it or could it be that those files are used or will be referenced by cloverX64efi? 

 

So I'm kind of lost in my thoughts and if anybody can help me clarify that would be AWSOME! 

Or point me to some documentation if any exist. 

 

Yes I've searched the fracking web first.

You need to understand the difference in starting UEFI Clover and Legacy Clover.

That doesn't explain bootx64.efi. BOOTX64.efi is the default "fallback" path for an UEFI boot file. As the default it will always be looked for and loaded without the need of adding an additional boot entry. It can be almost any .efi app or executable thats renamed to BOOTX64.efi. On an UEFI Clover install its a CLOVERX64.efi renamed so it will be loaded automatically without needing to set its full path to file as a boot entry, there is the option to do so in its main menu.

If I understand correctly, using a Clover install,

/Volumes/EFI/EFI/BOOT/BOOTX64.efi

and 

/Volumes/EFI/EFI/CLOVER/CLOVERX64.efi

Are the same file, CLOVERX64.efi was renamed to BOOTX64.efi to enable the UEFI to find it automatically?
