[G4] Empty set symbol on the screen

Hello all,

This seems to be the best answer. It seems that my MDD lost the  
startup drive setting because it couldn't simultaneously power a pair  
of external Firewire drives. Per TS1892, I held down the X key while  
rebooting, then reselected the startup drive.

Thanks to all,

Bruce
