NAME
     md -- memory disk driver

SYNOPSIS
     pseudo-device md [count]

DESCRIPTION
     The md driver enables use of system or user memory as a disk.  Memory for
     the disk must be allocated within the kernel or with mdconfig(8) before
     the md device may be used as a disk.  Its behaviour is configured by the
     kernel options MEMORY_DISK_HOOKS, MEMORY_DISK_IS_ROOT,
     MEMORY_DISK_ROOT_SIZE, MEMORY_DISK_DYNAMIC, and MEMORY_DISK_SERVER.

FILES
     /dev/md??   block mode memory disk devices.
     /dev/rmd??  raw mode memory disk devices.
