This is my 2-cents worth on the Startup Chime situation. First, at one time I had a Power PC 9500 and when I added a 3rd party G4 upgrade card, the tone of the startup chime changed. I called the company that made the G4 card and they gave me a big run around that the chime was not needed and they had no chimes on the factory units. My assumption was they screwed up the card and did not want to admit to the error. I replaced the 9500 with a real G4 machine.. For reasons I do not understand the volume of the G4 Startup Chime would change with time. The fix was very simple ..... just zap the pram and the volume came back normal. I could tell by sound of the start up tone when it was time to zap or reset the machine. The G4 has now been replaced with one of the new 24-inch 2.4 GHz iMacs and I am very pleased with the new Mac. BTW, if someone needs a good Apple G4-450 AGP processor card, drop me note. I upgraded the G4 to a G4 1GHz with a OWC card a few years ago. The 450 would be a good upgrade to 350 or 400. The 450 processor is a drop in card replacement for a Power PC Sawtooth. Dick
