Introduction 
Overview 
HP ProLiant Generation 2 and later servers have a configuration utility embedded in the system ROM. The 
configuration utility, RBSU, starts when you press the F9 key from the startup sequence.  
RBSU performs a wide range of configuration activities that may include: 
•  Configuring system devices and installed options 
•  Displaying system information 
•  Selecting the primary boot controller 
•  Configuring online spare memory 
 
 
IMPORTANT: Menu options may differ from those in this document, depending on specific 
server options. 
 
Based on the generation of the server blade, this user guide is divided into two sections: 
•  HP ProLiant G7 servers or server blades ("RBSU menu (HP ProLiant G7 servers or server blades)" on 
page 9) 
•  HP ProLiant G6 and earlier servers or server blades (including the HP ProLiant servers and server 
blades with AMD processors) ("RBSU menu (HP ProLiant G6 and earlier servers or server blades)" on 
page 103) 
 
Running RBSU 
1.  To run RBSU and modify configuration settings, press the F9 key when prompted during the startup 
sequence. 
2.  Modify configuration settings as needed. 
3.  Exit RBSU by pressing Esc at the main menu. To confirm configuration setting changes, reboot the 
system when exiting RBSU.
