Actually, I would like to activate that motherboard beeper too.
I wrote a program years ago, before I had any sound card on my
MS-Dos PC to generate something on it.   You could vary the 
frequency (tone) and length of beep and that just suited an
experiment I was doing.  I don't know how to do that from a
current machine running any UNIX varient (CentOS, FreeBSD, etc)
That information may be out there, but I haven't tried lately
to dig it up.   If you know or have some pointers, it could
be helpful.
