lilo cross install

santana · 01-20-2008, 01:13 PM

I am attempting to cross install linux on a router board(soekris net4521) from my workstation. The media is a compact flash card. I am having difficulty getting lilo installed.

I have made a bootstrap linux install on the cf drive which is mounted from /dev/sdd on /home/me/target.

The primary issue seems to be that in target /dev there are no hd* devices. This my first cross install so I don't know if this is expected or not, and all of the guides I have seen suggest to use grub, which has some issues with my disk geometry. As a result, It was advised that I use lilo instead. I tried to install lilo two ways:

first try, "chroot"

lxion:~$sudo chroot target /bin/bash
root:/# mount -a
root:/# lilo -C /etc/lilo.conf
Fatal: stat /dev/sdd: No such file or directory

hmmm. no luck there. Even though the cf drive is mounted on /dev/sdd iny workstation file system it doesn't show up in the chroot'ed file system /dev...

second try, "external"
lxion:~$sudo lilo -C target/etc/lilo.conf
Warning: LBA32 addressing assumed
Warning: The boot sector and map file are on different disks.
Warning: no PROMPT with SERIAL; setting DELAY to 20 (2 seconds)
Fatal: Illegal 'root=' specification: /dev/hda1

I see that I did something bad with the map file, it should be going on what ever is to be /dev/hda1. I know for sure that when the router boots it's bios reports the cf disk as /dev/hda so I am hesitant to change this...

Now, I have exhausted the options that I know of, and google didn't turn up any thing too useful

this is my lilo.conf

# NOTE: boot and disk below must be set to wherever your distro
# is currently mounted (while you're installing LILO). Don't mess
# with anything else unless you really know what you're doing.
boot = /dev/sdd
disk = /dev/sdd
bios = 0x80

delay = 1
serial=0,9600n8

image = /boot/vmlinuz-2.6.22-14-generic
root = /dev/hda1
append="console=ttyS0,9600n8"
label = soekris-2.6.22-14
read-only

can you advise?

thanks

boot = /dev/sdd
disk = /dev/sdd
bios = 0x80

I would say that boot=/dev/sdd correctly tells your workstation what disk to use to install lilo on the MBR. But I think that the combination of disk = /dev/sdd and bios = 0x80 is supposed to tell lilo what router board BIOS address corresponds to the boot device address on the router board. Therefore I would try:

disk = /dev/hda
bios = 0x80

Before chrooting, try
mount --bind /dev /home/me/target/dev
mount -t proc proc /home/me/proc
and then
chroot /home/me/target /bin/bash

Nice! I tried it but still:

Code:

lxion:~$sudo mount --bind /dev /home/burlen/target/dev
lxion:~$sudo mount -t proc proc /home/burlen/target/proc
lxion:~$sudo chroot target /bin/bash
root:/# lilo -C /etc/lilo.conf

Fatal: Illegal 'root=' specification: /dev/hda1

I was kind of leary about this, because the lilo.conf I have comes froma working install. But, I am out of my leage here, so I tried it. Unfortunately similar "Fatal: illegal" results were returned.

I really appreciate the feedback, thanks.
