We use a few different methods to install operating system images.

The signed installation methods are the same for XO-4, XO-1.75, XO-1.5 and XO-1. This was by design, since we do not wish to increase the training burden for the deployment teams.
A deployment will typically sign their builds and inject deployment keys at manufacture or on site.
The unsigned installation methods depend on the type of internal storage. XO-1 has raw NAND Flash. XO-1.5, XO-1.75 and XO-4 have microSD or eMMC managed Flash.
