Hi,

In my bios I' ve an option
IDE Hard Drive Acoustics Mode which can be set at:
[bypass] (now)
[quiet]
[Suggested]
[Performance]

What is this? Has this anything to do with the quietness of my hard drive?

It a dell worstation 360.



Also kinda dived into IRQs. Can someone say whether I've to change 
something?
