195	across interfaces that describe the type or class of hardware that is publishing\r
196	the block I/O interface. This enumeration will allow for policy decisions\r
197	in the Recovery PEIM, such as "Try to recover from legacy floppy first,\r
198	LS-120 second, CD-ROM third." If there are multiple partitions abstracted\r
199	by a given device type, they should be reported in ascending order; this\r
200	order also applies to nested partitions, such as legacy MBR, where the\r
201	outermost partitions would have precedence in the reporting order. The\r
202	same logic applies to systems such as IDE that have precedence relationships\r
203	like "Master/Slave" or "Primary/Secondary". The master device should be\r
204	reported first, the slave second.\r
