Download and installation

Development builds are available here:

• http://build.laptop.org/12.1.0

New builds are announced on the devel mailing list.

XO-1.75 and XO-1.5

To install from Open Firmware on an unlocked XO-1.5 or XO-1.75, download a .zd file to a USB drive. Choose the correct one: there are several. Files which end in .zd2 are for 2GB media and .zd4 is for 4GB media.

Insert the USB drive into the XO-1.5, get to the Ok prompt and type:

fs-update u:\osXX.zdN

Where osXX.zdN is the file you downloaded, for example os22.zd4.

XO-1

To install from Open Firmware on an unlocked XO-1, download the .onu and .uim files to a USB drive.

Insert the USB drive into the XO-1, get to the Ok prompt and type:

update-nand u:\osXX.onu

where osXX.onu is the .onu file you downloaded, for example os22.onu.

(Watch out, there's a trap. Never use copy-nand for this file format. copy-nand was for previous releases with .img and .crc files, but we no longer use it for .onu and .uim files. copy-nand might seem to finish okay, but your XO-1 won't start. If that happens, do it again using update-nand as above.)

Developers

The release is built with Build system::OS Builder version Build system version::5.0.x (master) under Build platform::Fedora 17, using f17-xo1.ini, f17-xo1.5.ini and f17-xo1.75.ini at this point in the development process. The f17, f17-xo1, f17-xo1.5 and f17-xo1.75 RPM dropboxes are used.
