Many boards will come ready (DRD + DSC) if you just wait for a minute after powering on. Others you have to attach to a hard drive with a piece of paper between the PCB and preamp so it can just spin up the motor.
But as a last resort you can always use boot ROM code utility. You just have to attach a terminal connection which you can do using that funny looking calypso board that comes with PC-3000. There's a picture of how to do it in this thread: http://ts.acelaboratory.com/index.php?/ ... connection
