Resetting the System OpenBoot Firmware

SPARC/CPU−56T 103

Resetting the System

If your system needs to be reset, there are two possibilities:

S Software reset

For this type of reset, use the command reset at the Forth command line.

S Button power−on reset

In both cases the system begins with the initialization procedures. If the system is reset via

a button power−on reset, the power−on self test is executed before the initialization if the

NVRAM configuration variable <diag−switch?> is set true.
