No, setting the boot pref from within OS X is the same as setting it  
from within OS 9.  It sets the OpenFirmware (read BIOS) default boot  
device. I thought maybe you were trying to do this diskless, in which  
case you'd have to go with the open firmware option.
To set it back to local booting, it depends on what OS is on the HD.   
If OS 9, you could zap the PRAM by powering on and holding down the  
Command + Option+P+R and let chime a few times. That should let it  
startup from the HD.  Once you're in OS 9 you can set the default  
boot device from within the Startup Disk Control Panel.
If you have OS X installed, you can just hold down the Option key  
after powering on and you should be presented with a list of possible  
startup devices to choose from.Once you're in OS X you can set the  
default boot device from within System Prefs.
