NOTE:  The server may not support all the following examples. 
NOTE:  If the boot drive is not empty or has been written to in the past, 
ORCA does not automatically configure the array. You must run ORCA 
to configure the array settings.

To change any ORCA default settings and override the auto-configuration 
process, press the F8 key when prompted. 
By default, the auto-configuration process configures the system for the English 
language. To change any default settings in the auto-configuration process, such 
as the settings for language, operating system, and primary boot controller, 
execute RBSU by pressing the F9 key when prompted. After the settings are 
selected, exit RBSU and allow the server to reboot automatically. 
For more information, refer to the HP ROM-Based Setup Utility User Guide on 
the Documentation CD or the HP website 
(http://www.compaq.com/support/techpubs/whitepapers
). 
 
Boot Options 
After the auto-configuration process completes, or after the server reboots upon 
exit from RBSU, the POST sequence runs, and then the boot option screen is 
displayed. This screen is visible for several seconds before the system attempts to 
boot from either a diskette, CD, or hard drive. During this time, the menu on the 
screen allows you to install an operating system or make changes to the server 
configuration in RBSU.
