 | |
| 
 | |
|   @par Note:
 | |
|       The MediaInfo structure describes an enumeration of possible block device
 | |
|       types.  This enumeration exists because no device paths are actually passed
 | |
|       across interfaces that describe the type or class of hardware that is publishing
 | |
|       the block I/O interface. This enumeration will allow for policy decisions
 | |
|       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
 | |
|       same logic applies to systems such as IDE that have precedence relationships
 | |
|       like "Master/Slave" or "Primary/Secondary". The master device should be
 | |
|       reported first, the slave second.

 | |
|       The MediaInfo structure describes an enumeration of possible block device

 | |

|       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
 | |
|       same logic applies to systems such as IDE that have precedence relationships
 | |
|       like "Master/Slave" or "Primary/Secondary". The master device should be

|       reported first, the slave second.
