The FailSafe Boot Block ROM allows for system recovery in the unlikely event of a ROM flash failure, as for example if a power failure were to occur during a ROM upgrade. The Boot Block is a flash-protected section of the ROM that checks for a valid system ROM flash when power to the system is turned on.

The following table lists the various keyboard light combinations used by the Boot Block ROM, as well as the meaning and action associated with each combination. Refer to the Desktop Management Guide for more detailed information.
