The loader should just be using BIOS calls and should work with almost
any system that presents the SD card as a bios disk device.  IIRC when
booting with an SD card in the slot the loader finds drives C to E,
which, again IIRC are:
C:	nvme
D:	USB to SATA disk in external enclosure
E:	SD card

The output of that was included in my original mail, and is still
