Welcome to the 64-bit Fedora 18 installer!                                      
Hit <TAB> for boot options.                                                     
                                                                                
                                                                                
Welcome to yaboot version 1.3.17 (Red Hat 1.3.17-6.fc18)                        
Enter "help" to get some basic usage information                                
boot: help                                                                      
                                                                                
Press the tab key for a list of defined images.                                 
The label marked with a "*" is is the default image, press <return> to boot it. 
                                                                                
To boot any other label simply type its name and press <return>.                
                                                                                
To boot a kernel image which is not defined in the yaboot configuration         
file, enter the kernel image name as [[device:][partno],]/path, where           
"device:" is the OpenFirmware device path to the disk the image                 
resides on, and "partno" is the partition number the image resides on.          
Note that the comma (,) is only required if you specify an OpenFirmware         
device, if you only specify a filename you should not start it with a ","       
                                                                                
To boot a alternative initrd file rather than specified in the yaboot           
configuration file, use the "initrd" command on Yaboot's prompt:                
"initrd=[name.img]". This will load the "name.img" file after the default       
kernel image. You can, also, specify a different initrd file to any other       
label of the yaboot configuration file. Just type "label initrd=[name.img]"     
and the specified initrd file will be loaded.                                   
                                                                                
To load an alternative config file rather than /etc/yaboot.conf, enter          
its device, partno and path, on Open Firmware Prompt:                           
boot conf=device:partno,/path/to/configfile                                     
.To reload the config file or load a new one, use the "conf" command            
on Yaboot's prompt:                                                             
conf [device=device] [partition=partno] [file=/path/to/configfile]              
                                                                                
If you omit "device" and "partno", Yaboot will use their current                
values. You can check them by entering "conf" on Yaboot's prompt.               
boot: conf
