+ in the Recovery PEIM, such as "Try to recover from legacy floppy first, \r

+ by a given device type, they should be reported in ascending order; this \r
+ order also applies to nested partitions, such as legacy MBR, where the \r
+ outermost partitions would have precedence in the reporting order. The \r
+ same logic applies to systems such as IDE that have precedence relationships \r
+ like "Master/Slave" or "Primary/Secondary". The master device should be \r
+ reported first, the slave second.\r
