Hi !

I use FreeBSD 4.9, an on my computer, the CD-ROM seems to support
"automatic acoustic management" (see results of atacontrol cap below).

How can I enable this feature (which seems disabled by default ?) Is
there an utility to do it under FreeBSD ?

Thank you very much in advance,

Regards,

js
