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 xo-backup, xo-repart, and xo-restore scripts, (these may be destructive, look at them before you use them),

• includes reversion server and client, for rapidly undoing filesystem changes made by laptop use, in test collections or shared classrooms.

Downloads

• XO-1 and XO-1.5, microcore-3.4-xo-2011-01-18.tar (15 MB) (md5sum b2b69b4b2c73e713d9b6c062d627f780)

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

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
