=== Instructions ===
== Prepare USB Drive ==


* unpack the tar file, on a USB drive (FAT or ext2 filesystem), for example:
* select a USB drive of at least 128 MB capacity, (it may have either a FAT or ext2 filesystem),


=== Linux - GNOME and Firefox ===
cd /media/FRED
tar xf microcore-3.4-xo-1.5-2011-01-06.tar


* boot the laptop from the drive,
* insert the USB drive,


* click on the zip file link above, and a dialog window will appear asking you what you want done with the download,
* after a short wait you will see the system prompt:


* accept the default to open it in Archive Manager, and the Archive Manager window will appear,

* click on ''Extract'', and a dialog window will appear asking you where to extract to,

* click on the USB drive in the ''Places'' list, then click on the ''Extract'' button, a dialog window will appear to tell you it worked,

* close the dialog window,

* close the Archive Manager window,

* close the Downloads window,

* eject the USB drive.

=== Linux - Terminal ===

* download the zip file using the link above, to the USB drive:

cd /run/media/olpc/FRED
wget ${URL}

* extract the zip file, at the top of the USB drive:

cd /run/media/olpc/FRED
unzip core-4.7.7-xo-2015-11-14.zip

* delete the zip file if you like, it is not required further,
rm core-4.7.7-xo-2015-11-14.zip

* eject the USB drive:

umount /run/media/olpc/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 zip file, and the contents will be expanded, a new folder ''boot'' will be created,
* delete the zip file if you like, it is not required further,
* eject the USB drive.

=== Windows ===

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

== Prepare laptop ==

* ensure the laptop is [[Activation_and_developer_keys|unsecured]], or sign the kernel and initrd files with your deployment keys,
* insert the USB drive into the laptop,

== Boot laptop ==

* turn on the laptop, and the USB drive will be automatically read,
* after a short wait you will see the Tiny Core Linux system prompt:
root@box:~#
root@box:~#
* you may remove the USB drive.

Tiny Core Linux is now ready for your commands.

== Configure wireless ==

wifi.sh

The script scans for available networks, lists them, and allows you to choose one, and enter a password if necessary.

== Configure wired USB ethernet after boot ==

When a USB ethernet adapter is connected before boot, if drivers are present it will be configured and be ready for use. When the adapter is added after boot, configure the interface using DHCP:
udhcpc

== Installing additional utilities ==

* additional utilities needed for a task can be installed:
su -c 'tce-load -wi rsync' tc

See the Tiny Core Linux documentation for more detail.

== Additional shells ==

* additional shells can be started using Alt/F2, username tc.

== Access to XO-1 filesystem ==

* you can mount and investigate the XO's [[JFFS2]] flash filesystem, for example:
cat /proc/mtd
mkdir /mnt/root
mount -t jffs2 mtd0 /mnt/root

== Access to XO-1.5, XO-1.75 and XO-4 filesystem ==

* you can mount and investigate the XO's eMMC or microSD filesystems, for example:
cat /proc/partitions
mkdir /mnt/boot /mnt/root
mount /dev/mmcblk0p2 /mnt/boot
mount /dev/mmcblk0p2 /mnt/root


== Backup and Restore ==
* configure wireless manually:


See [[Backup]] for how to use Tiny Core Linux for backup and restore of a laptop.
root@box:~# iwlist eth0 scan
root@box:~# iwconfig eth0 essid mynetwork


See [[/Save Journal|Save Journal]] for how to use Tiny Core Linux for backup of the Sugar Journal on multiple laptops.
* a DHCP client is in the background waiting to act when a network interface comes up.


== microcore 3.0 for XO-1 ==
== Reversion ==


See [[/Reversion|Reversion]] for how to use Tiny Core Linux to revert an XO with OLPC OS to a pristine filesystem configuration, as if it had just been installed. This can be used to quickly clean a set of class specific or loaned laptops.
The latest build for XO-1 is based on microcore 3.0. Download [http://dev.laptop.org/~quozl/tinycore/microcore-3.0-xo-1-2010-08-02.tar 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).


== Remote Diagnosis ==
== tinycore 2.8 with GUI for XO-1 and XO-1.5 ==


* connect a USB ethernet adapter or [[#Configure_wireless|configure wireless]],
In January 2010 a version based on microcore 2.8 [http://lists.laptop.org/pipermail/devel/2010-January/027364.html was announced] for both the [[XO-1]] and [[XO 1.5]].
* run our script:
xo-remote
* respond to the password change prompts for the user {{Code|tc}},
* wait for script to complete, and note the IP address of the laptop:
* set up inbound port forwarding on router if required,
* connect your OpenSSH client,

See also remote diagnosis using firmware only.

Boot from JFFS2 on XO-1

Mount the JFFS2 filesystem, save the original boot directory, and make a new one:
