Demo Diagnostic OS Installer¶
The ONIE distribution also comes with a demonstration diagnostic installer. This is an installer that illustrates how to write an installer for a diagnostic image as discussed in Hardware Diagnostics [Optional].
The demo diag OS installer illustrates a number of concepts, useful for hardware vendors creating their own hardware diagnostic installers:
- Where the diag image resides in the system
- How to boot the diagnostic image from ONIE
- Other architecture specific requirements for diagnostic images
Building the Demo Diag OS Installer¶
Building the demo diag OS installer follows the same mechanism
described in the Building the Demo Installer section. Just build the
demo target.
This Makefile target will build both the demo OS installer and the
demo diagnostic OS installer. When compilation finishes, the demo
diagnostic OS installer is located in
build/images/demo-diag-installer-<platform>.bin.
Installing the Demo Diag Installer¶
Install the demo diagnostic OS the same way you install any other ONIE OS installer.
Note
The order of operations in the factory for installing a diag on a new machine must follow:
- Install ONIE
- Install the diagnostic OS
