.Sh NAME
.Nm boot98cfg
.Nd HDD boot manager installation utility
.Sh SYNOPSIS
.Op Fl B
.Op Fl i Ar boot0
.Op Fl m Ar boot0.5
.Op Fl s Ar secsize
.Op Fl v Ar version
.Op Fl f Ar boot0.bak
.Op Fl F Ar boot0.5.bak
.Ar disk
.Sh DESCRIPTION
On NEC PC-98s,
.Sq boot loader
consists of the
.Sq IPL
and
.Sq HDD boot menu.
The IPL occupies sector 0 of a disk and is followed by the partition
table. The IPL loads the HDD boot menu that starts from 0x400.
The
.Nm
installs and makes backup copy of the IPL and the HDD boot menu; and
allows changing the version number field in the sector 0.
Note that the format command in NEC's OSs replaces the HDD boot menu
with its own HDD boot menu when the version number field is smaller
than that in the format command.
The options are:
.Bl -tag -width indent
.It Fl B
Install the IPL and HDD boot menu. This option causes the IPL and HDD
boot menu code to be replaced.
.It Fl i Ar boot0
Specify which IPL image to use. The default is /boot/boot0.
.It Fl m Ar boot0.5
Specify which HDD boot menu image to use. The default is
/boot/boot0.5.
.It Fl f Ar boot0.bak
Specify that a backup copy of the preexisting IPL should be written to
.Ar boot0.bak .
This file is created if it does not exist, and truncated if it does.
.It Fl F Ar boot0.5.bak
Specify that a backup copy of the preexisting HDD boot menu should be
written to
.Ar boot0.5.bak .
This file is created if it does not exist, and truncated if it does.
.It Fl v Ar version
Specify the version number.
.It Fl s Ar secsize
Specify the sector size. The default secotor size is 512
(bytes/sector).
