I was wondering when I first read about this - was it only disabled on power on, but still occured on a restart?

Short question for clarification: is my interpretation correct that the first of these commands disables the boot chime, while the second enables it?
 
I have two questions:
  1. Could I enable AutoBoot on my older Mac?
  2. Can I have both the chime and AutoBoot on my new Mac?

Oh man you spoiled a headline news with virtually all IT tech website - they are sooooo lame to not figure it out.

You are champ!

Kudos or should I say kiitos!

You brought back, and I quote: "iconic Mac startup chime" - haters will be sooo disappointed.
