OpenBoot Diagnostics

Like POST diagnostics, OpenBoot Diagnostics can be run if the diag-switch?variable is set to true.

You can also run OpenBoot Diagnostics interactively and select which tests you want it to perform. To do so, follow the steps below from the ok prompt.

1. Type:

ok setenv diag-switch? true ok setenv auto-boot? false ok reset-all

2. Type:

ok obdiag

This displays the OpenBoot Diagnostics menu:
