Can I make grub beep?

Yeah, as Samuel said in his response, I looked it up in a table when I 
figured out how to make it play "On Wisconsin".

I'd be interested in copying your grub directive for playing Ode to Joy. 
When you get that figured out, would you post it here, please? I am 
always looking for more tunes because I like to have grub play different 
tunes depending on the boot medium and version of the operating system. 
  If I'm trying to boot from a CD and it plays "On Wisconsin" instead of 
"Close Encounters", I know it didn't work.

Anybody else have interesting ones, let me know.

I've included an example line that plays a few notes of "On Wisconsin" This is not entirely trivial in that it makes it very clear when to interrupt the boot process in order to select an operating systems. I always tell my end users to press the down arrow once when they hear "On Wisconsin".
