====== Install HDD Version ======

**Caution : OBSOLETED document, need to rewrite..**

Note : It is recommend use HDD version if stopped during boot, not bootable, memory of target machine is under 64MB.

Currently opencocon hasn’t its installer. so we recommend manual install. Below is how to install opencocon to Harddisk or CF memory card :

Method of install is like Gentoo, so it is easy to install you’re already understand install Gentoo. (maybe..)

===== 0. Boot install-base GNU/Linux distribution =====

You can use Live-CD base distribution(KNOPPIX, Ubuntu, opencocon, …), or Desktop GNU/Linux (if install to another Harddisk, without daily-using Harddisk) to install opencocon.
If you try install to another harddisk, install-base machine must be x86 or x86_64 architecture.

In this manual, Harddisk to install is /dev/sdb . If your target is wrong, replace /dev/sdb to your target.

WARNING : I strongly recommend backup data of target harddisk!
opencocon is not usable for Multi-boot!

===== 1. Prepare Partition =====

Run cfdisk :
<code>
# cfdisk /dev/sdb
</code>

and allocate ext3 patrtiton, for example /dev/sdb1

WARNING : Dont forget select another harddisk of your working.

At least needs 200MB of free space in partiton.
If your target machine is less of memory (about ~64MB), allocate swap partition, for example /dev/sdb2

CAUTION : opencocon supports only ext2/ext3 partition.

After allocate, Select [Write] and [Exit].

===== 2. Format harddisk =====

After allocate opencocon partition, run format like :
<code>
# mke2fs -j /dev/sdb1
</code>

and if you allocated swap partition, prepere like :
<code>
# mkswap -v1 /dev/sdb2
</code>

===== 3. Mount to temporary place =====

Next, mount opencocon partition. For example, mount to /mnt.
<code>
# mount /dev/sdb1 /mnt
</code>

And move current-directory
<code>
# cd /mnt
</code>

===== 4. Extract opencocon-tree =====

Check right place to extract?
<code>
# pwd
/mnt
</code>

If ok, extract opencocon tarball.
<code>
# tar -xzvpf /(Your opencocon-tarball directory)/opencocon-v2…..tar.gz
# tar -xzvpf /(Your opencocon-tarball directory)/modules-….tgz
</code>

===== 5. Setup GRUB bootloader =====

to run GRUB, mount these partition (/proc and /dev).
<code>
# mount -t proc none /mnt/proc
# mount -o bind /dev /mnt/dev
</code>

Enter chrooted enveroiment,
<code>
# chroot /mnt /bin/sh
# grub
</code>

On GRUB prompt, input like :
<code>
(grub) root (hd1,0)
(grub) setup (hd1)
</code>

WARNING : You must understand install place of bootloader.
If you select wrong partition, your working enveronment losts bootable.

Almost case, partition mapped GRUB like :
<code>
/dev/sda1 : (hd0,0)
/dev/sdb : (hd1) /dev/sdb1 : (hd1,0)
…
</code>

For more information, please read GRUB manual before install.

After install,
<code>
(grub) quit
</code>

and Exit chroot-ed enveronment
<code>
# exit
</code>

===== 6. Swap setting =====

Currently opencocon can’t detect swap partition automaticly.
Place this command
<code>
swapon /dev/sda2
</code>

to right place of /sbin/setup.sh

===== 7. Clean up =====

<code>
# sync
# cd /
# umount /mnt/proc /mnt/dev /mnt
</code>

Eject harddisk, and setup to your target machine, and boot.
