Our software

OLPC is working with Red Hat on a Linux kernel for the machine, but we are opening up the design; it is inevitable that there will be several variants of Linux to chose from, as well as some version of Windows, and perhaps an OS X offering.

Notes on using the OLPC developer boards

See Jim's Aug 31 post to the OLPC-Devel list
(http://mailman.laptop.org/mailman/listinfo/devel)

• OLPC-devel Please convert your boards to LinuxBIOS
• Upgrading to LinuxBIOS

and a much more detailed explanation of the issues on the Devel-boards list:

• OLPC-Devel-boards Announcement: Conversion to LinuxBIOS must be complete by August 26.

fyi: http://wiki.laptop.org/go/Linuxbios, and http://www.linuxbios.org/index.php/Main_Page

after installing LinuxBios you continue with:

http://wiki.laptop.org/go/Upgrading_to_LinuxBIOS#Continuing_with_an_Installation

You need to get a dev image onto a usb stick or a usb drive and then use the LinuxBios to startup which then starts the dev image. This updates LinuxBios and then you need to reboot.

Now you should have a working linux with a minimal layer of sugar running on top.

You can load a full Fedora dev environment if you need it Installing Fedora Core. The build images are described here: OS images. There are also tools for installing system to the Flash disk: Installing to NAND.
