Can Clover boot the nvme disk under legacy BIOS?

1. Hi, everyone.
   
   My workstation have no UEFI support. I install OS X or Windows 10 on a nvme disk, then install Clover on a USB disk. Uder legacy BIOS, I boot Clover from the USB disk, and boot the OS on the nvme disk, at last I seems to boot from the nvme disk under legacy BIOS. Does it work?
   
   I give this question because I think Clover makes a virtual EFI environment when it's up, and there is a nvme driver under driver64 folder. So I think it may work. If it works, I wonder set up a nvme disk for my workstation.
   
   Maybe I don't express it clearly.
   The question is: Can Clover that installed on a usb disk or a hard disk boot windows 10 or OS X installed on a pcie nvme disk under legacy bios or UEFI bios without nvme support ?

For Legacy BIOS to be able to boot from a PCIe boot drive the PCIe card has to have its own boot firmware and control chip.
Legacy BIOS has never directly supported booting from a PCIe drive.

Thanks a lot for your reply.
Yeah, I think you are right, and I heard, for example, some Rocket raid card has its own efi boot firmware, and can boot OS X directly.

My trouble is: UEFI bios contains nvme driver, can boot nvme disk. Clover create a virtual EFI environment when it is up, and contain Nmveexpressdxe64.efi driver. So I think Clover may boot a nvme disk directly. I don't make a try because I have no a nvme disk.

From what I understand, OS Sierra contains no support for NVME booting - there is a kext or Clover patch available, but since I have no NVME drive to test it on I cannot say for certain. Forum search is your friend here.

I already make a try. Under legacy bios, clover with nvmexpressdxe64.efi driver, can know and boot a pcie nvme disk. I install windows 10 on the nvme disk, and boot the windows normally, just like under a UEFI bios with nvme support.
