+.Sh NAME
+.Nm installboot
+.Nd install bootstrap software on an FFS partition
+.Sh SYNOPSIS
+.Nm installboot
+.Op Fl nv
+.Ar boot
+.Ar bootxx
+.Ar device
+.Sh DESCRIPTION
+The
+.Nm installboot
+utility prepares an FFS partition for bootstrapping.
+.Pp
+The NetBSD/alpha disk bootstrap software is split into two parts:
+a small first-stage boot program that is written into the disklabel
+area of a disk
+.Po
+and hence is limited in size to 7680 bytes
+.Pc ,
+and a second-stage boot program that resides in the filesystem proper
+.Po
+typically with the name 
+.Pa /boot
+.Pc .
+The first-stage boot program is loaded into memory by the SRM console
+software.  After receiving control of the system, it loads the
+second-stage boot program from a set of filesystem block numbers that
+have been
+hard-coded into it by
+.Nm installboot .
+The second-stage boot program locates and loads the kernel.
+.Pp
+The second-stage boot program and the prototype code for the
+first-stage boot program can be found in
+.Pa /usr/mdec/boot
+and
+.Pa /usr/mdec/bootxx ,
+respectively.
+.Pa /usr/mdec/boot
+may be installed simply by copying it to the root directory of the
+partition you wish to boot from, but after it is installed
+.Nm installboot
+.Em must
+be run.
+.Pp
+The options recognized by
+.Nm installboot
+are as follows:
+.Bl -tag -width flag
+.It Fl n
+Do not actually write anything on the disk.
+.It Fl v
+Verbose mode.
+.El
+.Pp
+The arguments are:
+.Bl -tag -width bootxx
+.It Ar boot
+The name of the second-stage boot program in the file system
+where the first-stage boot program is to be installed.
+.It Ar bootxx
+The name of the prototype file for the first-stage boot program.
+.It Ar device
+The name of the raw device in which the first-stage boot program
+is to be installed.  
+This should be the raw device containing the file system
+which holds
+.Ar boot .
+.El
+.Sh EXAMPLES
+The following command will install the first-stage boot program in the
+root filesystem
+.Pq assumed to be mounted from Dq sd0a
+using the file
+.Pa /boot
+as the second-stage boot program:
+.Bd -literal -offset indent
+installboot /boot /usr/mdec/bootxx /dev/rsd0a
+.Ed
+.Sh BUGS
+NetBSD/alpha systems are only capable of booting off of disks'
+.Dq a
+partitions, and bootable partitions must start at the beginning
+of the disk.
+.Pp
+.Nm Installboot
+requires simultaneous access to the mounted file system and
+the raw device.
+That is not allowed with the kernel
+.Dv securelevel
+variable
+.Po
+see
+.Xr sysctl 8
+.Pc
+set to a value greater than zero, so
+.Nm installboot
+only works when the system is in
+an insecure mode (e.g. single-user mode; see
+.Xr init 8 ).
+.Sh "SEE ALSO"
+.Xr disklabel 8 ,
+.Xr init 8 ,
+.Xr sysctl 8
+.Sh HISTORY
+The NetBSD/alpha
+.Nm
+command first appeared in
+.Nx 1.2 .
