.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).
