+.Os FreeBSD
+.Sh NAME
+.Nm mount_hpfs
+.Nd mount an HPFS file system
+.Sh SYNOPSIS
+.Nm mount_hpfs
+.Op Fl o Ar options
+.Op Fl u Ar uid
+.Op Fl g Ar gid
+.Op Fl m Ar mask
+.Pa special
+.Pa node
+.Sh DESCRIPTION
+The
+.Nm
+command attaches the HPFS filesystem residing on the device
+.Pa special
+to the global filesystem namespace at the location
+indicated by
+.Pa node .
+This command is normally executed by
+.Xr mount 8
+at boot time, but can be used by any user to mount an
+HPFS file system on any directory that they own (provided,
+of course, that they have appropriate access to the device that
+contains the file system).
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl u Ar uid
+Set the owner of the files in the file system to
+.Ar uid .
+The default owner is the owner of the directory
+on which the file system is being mounted.
+.It Fl g Ar gid
+Set the group of the files in the file system to
+.Ar gid .
+The default group is the group of the directory
+on which the file system is being mounted.
+.It Fl m Ar mask
+Specify the maximum file permissions for files
+in the file system.
+.El
+.Sh EXAMPLES
+To mount an hpfs volume located in /dev/wd1s1:
+.Bd -literal -offset indent
+# mount_hpfs /dev/wd1s1 /mnt
+.Ed
+.Pp
+.Sh WRITING
+There is limited writing ability and it is not well-tested.
+It is strongly recomended to mount readonly!
+.Sh SEE ALSO
+.Xr mount 2 ,
+.Xr unmount 2 ,
+.Xr fstab 5 ,
+.Xr mount 8
+.Sh HISTORY
+The
+.Nm
+first appered in FreeBSD 3.0
+.Sh AUTHOR
+HPFS kernel implementation,
+.Nm
+and manual were written by Semen Ustimenko <semenu@FreeBSD.org>.
