This is SuperH boot.b for LILO.

You can use this program with LILO as /boot/boot.b.

* Use of LILO in cross development environment

Here's lilo.conf which I use:
------------------------------
linear
# Cross LILO
# Actually, it's /dev/hda
boot = /dev/hdc
disk = /dev/hdc
  bios=0x80
#
delay = 30
vga = normal
image = /boot/vmlinuz
	label = linux
	root = /dev/hda1
	read-only
------------------------------

As of SH BIOS 0.5, only LBA access is supported.  So, you must need
"linear" line.

It is better *not* to add "compact" line.  As SH BIOS doesn't check
how many multiple sectors can be read, it may not work.

In my cross environment, Compact Flash card is accessed as the device
/dev/hdc at the host.  This disk is shown as /dev/hda at the target
side.  I specify "boot = /dev/hdc" to write the MBR and `map' file in
the disk of /dev/hdc (at the host).  However, since the disk is shown
as /dev/hda at the target machine, special care is needed (or else,
/dev/hdc would be accessed in the target too).  That's the trick two
lines: "disk = /dev/hdc ... bios = 0x80", where 0x80 means /dev/hda
for BIOS.  With these lines, disk geometry uses 0x80 (/dev/hda).

If you mount /dev/hdc at /mnt, the invocation of LILO is:

	# lilo -r /mnt

You need to have /mnt/etc/lilo.conf and /mnt/dev/hdc, /mnt/dev/hda1 and
other files in the target disk under /mnt.
