 .Dt MD 4
 .Os
 .Sh NAME
 .Nm md
 .Nd memory disk
 .Sh SYNOPSIS
-.Cd device md
+To compile this driver into the kernel,
+place the following lines in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device md"
+.Ed
+.Pp
+Alternatively, to load the driver as a
+module at boot time, place the following line in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+geom_md_load="YES"
+.Ed
 .Sh DESCRIPTION
 The
 .Nm
 driver provides support for four kinds of memory backed virtual disks:
 .Bl -tag -width preload
 .It Cm malloc
 Backing store is allocated using
 .Xr malloc 9 .
 Only one malloc-bucket is used, which means that all
 .Nm
 devices with
 .Cm malloc
 backing must share the malloc-per-bucket-quota.
 The exact size of this quota varies, in particular with the amount
 of RAM in the
 system.
 The exact value can be determined with
 .Xr vmstat 8 .
 .It Cm preload
 A file loaded by
 .Xr loader 8
 with type
 .Sq md_image
 is used for backing store.
 For backwards compatibility the type
 .Sq mfs_root
 is also recognized.
 If the kernel is created with option
 .Dv MD_ROOT
 the first preloaded image found will become the root file system.
 .It Cm vnode
 A regular file is used as backing store.
 This allows for mounting ISO images without the tedious
 detour over actual physical media.
 .It Cm swap
 Backing store is allocated from buffer memory.
 Pages get pushed out to the swap when the system is under memory
 pressure, otherwise they stay in the operating memory.
 Using
 .Cm swap
 backing is generally preferable over
 .Cm malloc
 backing.
 .El
 .Pp
 For more information, please see
 .Xr mdconfig 8 .
 .Sh EXAMPLES
 To create a kernel with a ramdisk or MD file system, your kernel config
 needs the following options:
 .Bd -literal -offset indent
 options 	MD_ROOT			# MD is a potential root device
 options		MD_ROOT_SIZE=8192	# 8MB ram disk
 makeoptions	MFS_IMAGE=/h/foo/ARM-MD
 options 	ROOTDEVNAME=\\"ufs:md0\\"
 .Ed
 .Pp
 The image in
 .Pa /h/foo/ARM-MD
 will be loaded as the initial image each boot.
 To create the image to use, please follow the steps to create a file-backed
 disk found in the
 .Xr mdconfig 8
 man page.
 Other tools will also create these images, such as NanoBSD.

 .Sh HISTORY
 The
 .Nm
 driver first appeared in
 .Fx 4.0
 as a cleaner replacement
 for the MFS functionality previously used in
 .Tn PicoBSD
 and in the
 .Fx
 installation process.
 .Pp
 The
 .Nm
 driver did a hostile takeover of the
 .Xr vn 4
 driver in
 .Fx 5.0 .
 .Sh AUTHORS
 The
 .Nm
 driver was written by
 .An Poul-Henning Kamp Aq Mt phk@FreeBSD.org .
