10.2 OpenBoot Emergency Procedures for
Systems With USB Keyboards
The following sections describe how to perform the functions of the Stop-
commands on systems that have USB keyboards.
10.2.1 Stop-A Functionality
Stop-A (Abort) works the same as it does on systems with standard keyboards,
except that it does not work during the first few seconds after the machine is reset.
10.2.2 Stop-N Equivalent Functionality
1. After turning on the power to your system, wait until the front panel power-
indicator LED begins to blink and you hear an audible beep.
2. Quickly press the front panel power switch twice (similar to the way you would
double-click a mouse).
A screen similar to the following is displayed to indicate that you have successfully
reset the NVRAM contents to the default values. If a screen similar to the following
is not displayed, repeat steps 1 and 2.
