microcore 3.4 for XO-1 and XO-1.5

Announcing a build of Tiny Core Linux for XO-1 and XO-1.5.

Useful for testing and diagnosis without touching the internal storage. Added recently are combined XO-1 and XO-1.5 support, a few scripts for backing up, restoring, and reverting laptops.

Features

  • based on Tiny Core Linux 3.4 microcore variant, configured for a root shell in text mode, with additional shells on demand,
  • uses the OLPC kernel, for hardware support, based on the kernel from OLPC OS 10.1.3 build os860,
  • includes the wireless firmware shipped with OLPC builds, and binary redistribution of wireless and some filesystem tools from the OLPC builds,
  • includes reversion server and client, for rapidly undoing filesystem changes made by laptop use, in test collections or shared classrooms.

Downloads

Prepare USB Drive

  • select a USB drive of at least 128 MB capacity, (it may have either a FAT or ext2 filesystem),

Linux - GNOME and Firefox

  • insert the USB drive,
  • click on the tar file link above, and a dialog window will appear asking you what you want done with the download,

  • close the dialog window,
  • close the Archive Manager window,
  • close the Downloads window,
  • eject the USB drive.

Linux - Terminal

  • download the tar file using the link above, to the USB drive:
cd /media/FRED
wget ${URL}
  • extract the tar file, at the top of the USB drive:
cd /media/FRED
tar xf microcore-3.4-xo-2011-01-18.tar
  • eject the USB drive:
umount /media/FRED

Mac OS X

  • insert the USB drive,
  • control-click on the link above, select Download Linked File As ..., and a Save As dialog will appear,
  • change Where to the name of the USB drive, usually Untitled, then click on Save, the dialog will go away,
  • switch tasks to Finder, display the USB drive,
  • double-click on the tar file, and the contents will be expanded, a new folder boot will be created,
  • delete the tar file if you like, it is not required further,
  • eject the USB drive.

Windows

  • download the tar file,
  • insert the USB drive,
  • use WinZip or other operating system features to expand it onto the USB drive,
  • eject the USB drive.

Boot USB Drive

  • boot the laptop from the USB drive,
  • after a short wait you will see the system prompt:
root@box:~#
  • configure wireless manually:
root@box:~# iwlist eth0 scan
root@box:~# iwconfig eth0 essid mynetwork
  • a DHCP client is in the background waiting to act when a network interface comes up, it may take a few seconds,
  • additional utilities needed for a task can be installed:
root@box:~# su -c 'tce-load -wi rsync' tc
  • additional shells can be started using Alt/F2, username tc.

microcore 3.0 for XO-1

The latest build for XO-1 is based on microcore 3.0. Download microcore-3.0-xo-1-2010-08-02.tar (9.8 MB) and then follow the instructions above, subject to the following changes:

  • use the correct file name when unpacking the tar file,
  • use an ext2 filesystem only (or rename microcore.gz to initrd and change olpc.fth to suit).

tinycore 2.8 with GUI for XO-1 and XO-1.5

In January 2010 a version based on microcore 2.8 was announced for both the XO-1 and XO 1.5.

Ready version of Tiny Core Linux for the XO-1 are available here and instructions for installation (for tc_xo_mm) here

tinycore_xo is the minimal installation with just Xfbdev for display driver

tc_xo_with_apps adds a file manager, basic applications and Opera web browser

tc_xo_mm adds sound, audio and video players

tc_xo_X adds Xorg and functioning game keys

tc-xo_01 in 3 flavors is now available. See the build announcement for more

The tc-xo_02 based on tinycore v2.10 and unmodified OLPC kernel is now available. See the v02 build announcement for more
