at that point, I would simply install a really small SSD (something under 100 GB), have that do the boot handling and then setup to hand off to the NVMP drive. It seems simple enough. Hell, the USB boot idea works equally as well. Basically, anything that can allow you to use this new technology in your old hardware should be considered.
I have a few ideas on some work arounds I would like to explore. Just no money to make them happen.
