Note that signed installation methods are the same for XO-1 and XO-1.5. Intentional design, since we do not wish to increase the training burden for the deployment teams.
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 [[OSBuilder#Signing_preparation|sign their builds]] and [[Firmware_security#Adding_Deployment_Keys_to_Manufacturing_Data|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.

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.
