+Boot time autodetection of RAID arrays
+--------------------------------------
+
+When md is compiled into the kernel (not as module), partitions of
+type 0xfd are scanned and automatically assembled into RAID arrays.
+This autodetection may be suppressed with the kernel parameter
+"raid=noautodetect". As of kernel 2.6.9, only drives with a type 0
+superblock can be autodetected and run at boot time.
+
+The kernel parameter "raid=partitionable" (or "raid=part") means
+that all auto-detected arrays are assembled as partitionable.
