+# Module that lays Disk I/O protocol on every Block I/O protocol.\r
+#\r
+# This module produces Disk I/O protocol to abstract the block accesses\r
+# of the Block I/O protocol to a more general offset-length protocol\r
+# to provide byte-oriented access to block media. It adds this protocol\r
+# to any Block I/O interface that appears in the system that does not\r
+# already have a Disk I/O protocol. File systems and other disk access\r
+# code utilize the Disk I/O protocol.\r
