Hi Rick
NL "distributes" drive numbers in the order it looks for them and sees them. I suppose the change in Kernel is the reason why your drives 0 & 1 changed places.
I'm not 100% sure but I think that you cannot change the order of your hard drives WITHOUT changing their physical connection types. If you have a an external USB disk drive, try to disconnect the drive attached to the MB and plug in the USB drive. Boot NL and see the drive numbers. If this solves your problem, you can try to put the disconnected drive in a USB hard drive box and connect it to the NL server this way.
It may be easier to change your links to these drives instead of changing the drive' connections
