in the Recovery PEIM, such as "Try to recover from legacy floppy first,
LS-120 second, CD-ROM third." If there are multiple partitions abstracted
by a given device type, they should be reported in ascending order; this
order also applies to nested partitions, such as legacy MBR, where the
outermost partitions would have precedence in the reporting order. The
