Try unplugging the HD and see if it gets to the ? disk screen.   If so, 
you've got a dead HD.   If not, you may have a dead logic, and what you're hearing 
is the inverter section on the board trying to crank up.   

Do pull the PRAM batt for awhile, reset the Power Manager (30-45 sec hold on 
reset btn on reverse, no AC, no battery) and try again.   Might have just gone 
wonky.

I may have a 250 mg HD around here still, and I do have a good 280 logic, 
which will need an orig. clock chip reinstalled (currently hacked for 40 
mhz....).
