From: Bill Croft <croft@safe> Since the disk drive motor is shut off with a software timeout, it can remain on "forever" if you hit a breakpoint in macsbug while it's spinning. Bruce Horn offers this advice: Yep, you're right, it's timed in software. The address to kill the motor is the IWM, DFF1FF. Just do a DM DFF1FF in the debugger and it should turn the thing off. Bruce
