MP 1,1-5,1 Opencore Bootpicker Drive Order

[calmacfan]

I have the latest version of OpenCore 0.5.9 installed and it's fantastic. One thing I've been trying to figure out though is how the order of the drives as presented in the Bootpicker screen is determined. I have two bootable SSD's and a NVME drive with Mac OS Mojave, Windows and Mac OS Catalina installed. The order of the drives presented seems to vary depending on which SATA Port or PCIE slot the drives are installed in. Is there a protocol that OpenCore uses to determine the order in which it drops the Drives in the Bootpicker from left to right?

Any thoughts or input on this one?

Does anyone know the sequence that Opencore or the cMP uses when populating the BootPicker? Does it go to the SATA bays first or the PCIe Slots? Does it go survey 1-2 Optical, 1-4 SATA and then 1-4 PCIE? or the other way round? Any input would be appreciated.

Curious about relevance of this. What are you planning to do with this information?

Not sure about the order of the icons but to determine the default, change your startup disk in System Preferences

Listen a real Scenario. You have 2 macOS'es Installed on the SAME OR A DIFFERENT SSD. Sometimes you need to reset the NVRAM and when you do that the DEFAULT BOOT DRIVE you had selected vanishes and you need to set it again.. or it boots to the 1st available OS it picks on the picker. it would be really nice to be able to PICK a default Boot Drive that would persist EVEN after an NVRAM RESET. This is the issue I am facing because I have a lot of mac'oses. Also... For some reason WINDOWS are always first on the boot picker .. this is hilarious... After so many months and opencore releases... Has anyone found a solution to set the way drives are generated on the boot picker ?
