Audio: Initializes the audio system. For the audio system to
take effect, any startup option key must be pressed before the
end of audio initialization.
If the POST process stops and indicates an error on the LED or console in any one
of these subsystems, record the error number and refer to Chapter 8, “Determining
Hardware Problems.”
For more information on:
The System Management Services (started by pressing F1 or the numerical 1
key), see Chapter 3, “Using System Management Services.”
The Open Firmware command line (started by pressing F8 or the numerical 8
key), see Chapter 3, “Using System Management Services.”
Alternate boot modes (started by pressing F5 or the numerical 5 key, or F6 the
numerical 6 key), see “Working with System Startup Options.”
The last indicator to appear is the boot indicator. This indicator shows that the
server hardware is preparing to load and start the operating system.
At this point, the server prompts you for the power-on password if it has been set.
(See Chapter 3, “Using System Management Services,” for instructions on setting
passwords.)
If three incorrect responses are given to the password prompt, the server locks up
and must be turned off and turned on again to be reset. If the power-on password
has been lost, then the power-on password jumper must be reset or disabled:
To reset the power-on password, remove the server power cable; then remove
the server battery for 30 seconds. See “Changing the Battery” on page 4-36 for
the location of the battery.
To disable the power-on password, see “Enabling and Disabling the Power-On
Password” on page 4-8.
Attention: Removing the battery may also erase system configuration information
stored in the nonvolatile random access memory (NVRAM), such as the custom boot
list.
Note: If the privileged-access password has been lost, contact your authorized
reseller or marketing representative.
