.Dt INSTALLBOOT 8
.Os
.Sh NAME
.Nm installboot
.Nd install a bootstrap on a FFS disk or partition
.Sh SYNOPSIS
.Nm installboot
.Op Fl n
.Op Fl v
.Oo Fl s Ar spt Oc
.Oo Fl h Ar tpc Oc
.Ar boot
.Ar biosboot
.Ar disk
.Sh DESCRIPTION
.Nm installboot
is used to install a
.Dq first-stage
boot program into the boot area
of a FFS disk partition, and initialize the table of block numbers the
.Ar biosboot
program uses to load the second-stage boot program.
.Pp
The options are as follows:
.Bl -tag -width flag_opt
.It Fl n
Do not actually write anything on the disk.
.It Fl v
Be verbose, printing out the CHS (Cylinder, Head, Sector)
triples that are stored in
.Ar biosboot
along with lots of other information.
.It Fl s Ar spt
Used to specify the sectors-per-track value if the drive has
sector translation activated, and
.Nm
is unable to determine the translated geometry.
.\" If not specified, this defaults to d_nsectors from the disklabel.
If not specified, this defaults to the value retrieved from the BIOS
at boot time, available via
.Xr sysctl 8 .
.It Fl h Ar tpc
Used to specify the tracks-per-cylinder value if the drive has
sector translation activated, and
.Nm
is unable to determine the translated geometry.
.\" If not specified, this defaults to d_ntracks from the disklabel.
If not specified, this defaults to the value retrieved from the BIOS
at boot time, available via
.Xr sysctl 8 .
.El
.Pp
The arguments are:
.Bl -tag -width biosboot
.It Ar boot
The name of the second-stage boot program in the mounted file system
where the first-stage boot program is to be installed. This should be
a full pathname.
.It Ar biosboot
The name of the prototype file for the first stage boot program,
usually
.Pa /usr/mdec/biosboot .
.It Ar disk
The name of the disk containing the partition in which the second-stage
boot program resides and the first-stage boot program is to be installed.
This can either be specified in short form (i.e.,
.Sq sd0
or
.Sq wd0 ) ,
or as the explicit device node, such as
.Pa /dev/rsd0c
or
.Pa /dec/rwd0c .
.Pp
Note that you must be in single-user mode or have your kernel in
insecure mode (see the
.Xr sysctl 8
.Va kern.securelevel
variable or
.Pa /etc/rc.securelevel )
to enable access to the raw partition of a mounted disk.
.Pp
The
.Sq c
partition is always used to represent the
.Dq entire
disk on i386.
.El
.Sh EXAMPLE
The typical use is
.Pp
.Dl # cp /usr/mdec/boot /boot
.Dl # /usr/mdec/installboot -v -n /boot /usr/mdec/biosboot sd0
.Pp
And if the information supplied looks right, run the above without the
.Fl n
flag.
.Pp
If you are replacing much older versions of the bootblocks on your
drive, you will need to use the
.Fl s
and
.Fl h
arguments to installboot to properly install the bootblocks. You can
either get these figures in your BIOS, or by booting a new floppy
and typing
.Pp
.Dl boot> machine diskinfo
.Pp
.Sh BUGS
The disklabel
.Va d_type
field must be set to a value other than
.Dq unknown .
.Pp
You cannot run
.Nm installboot
for drives/partitions others then the one you want
.Pa /boot
loaded from.
