New page

The XO-1 laptop from the One Laptop Per Child project is uniquely suited for mobile mesh operations such as mapping spectrum usage.

Why?

*It uses only 4-6 watts of power.
*It can run on anything from 11 to 18 volts.
*The screen is viewable in direct sunlight.
*Your local hackerspace probably has one or more lying around unused.

This guide show how to get a modern distro (Debian 7.0) on a XO-1 laptop.

Ensure you have a jailbroken XO laptop ([http://wiki.laptop.org/go/Jailbreaking_the_XO#How_to_tell_if_your_laptop_is_secured how to check]).

= Jailbreaking =

If you need to jailbreak, keep pressing escape while booting the laptop until you get the "ok" prompt. That screen should tell you your laptop serial number and UUID.

Now go [https://activation.laptop.org/devkey/post/ here] (possibly on a different computer) and enter the serial and uuid and wait 24 hours.

The developer key is a file called develop.sig. Download develop.sig to /security on the XO laptop (or I believe it can be on a USB drive or SD card, but still in /security).

= Installing Debian =

The installation procedure is:

*First install DebXO 0.6 which will give you Debian Squeeze (6.0)
*Then dist-upgrade to Debian Wheezy (7.0)

== Installing DebXO ==

There's a nice guide [http://wiki.laptop.org/go/DebXO here].

Here's a short summary:

Download xfce.img and xfce.dat from [http://lunge.queued.net/~dilinger/debxo-latest/images/nand/ here].

Put xfce.img and xfce.dat on a usb stick with a vfat filesystem and plug into XO laptop.

Keep hitting escape while booting until you get the "ok" prompt.

Ensure you're running Q2E20 or later (it should say at the prompt).

At the prompt, type:

update-nand disk:\xfce.img

Wait for the flashing to finish.
Reboot into Debian (it may take a while to boot).

== Upgrading to Debian Wheezy (7.0) ==

First, set the root password:

sudo su -
passwd

If you don't do this, then you won't be able to get a recovery terminal later if things don't work out as expected.

For the rest of this guide, it is assumed that you are root.

Now, you can't actually run the upgrade with the amount of space available on the internal flash, so insert an external usb stick with some free space.

Unmount it if it automatically mounted (it probably did):

umount /dev/sda1

Now mount it in /var/cache/apt/archives so downloaded archives during the install are saved to the usb stick instead of the internal flash:

mount /dev/sda1 /var/cache/apt/archives

You'll need an internet connection. I'm assuming you have an unsecured wifi access point you can connect to:

iwconfig wlan0 essid <your_wifi_network_ssid>
dhclient -v wlan0

Ensure you have the newest version of Squeeze:

aptitude update && sudo aptitude safe-upgrade

Edit /etc/apt/sources.list so it only contains:

deb http://ftp.us.debian.org/debian wheezy main
deb http://security.debian.org/ wheezy/updates main

Run the upgrade:

aptitude update
apt-get dist-upgrade

(note: it is important that you use apt-get instead of aptitude for the dist-upgrade)

After the upgrade is complete, ensure that fsck.ubifs is installed:

apt-get install fsck.ubifs

Reboot and hope it works!
