How do I ring a bell?

In the good'ol days I could make UNIX ring a bell (literally) by sending
\a to the console TTY (an ASR33 in my case). Now there's an electronic
synthesised ting or beep from an terminal emulator IF it's got a sound
card and so on, and an IBM-PC had a beep routine in the BIOS.
Is there any way to make a noise through the built in "bell" speaker
found on an IBM PC compatible server box? Writing 007 to the BIOS cout
routine might do it, but I've realised I haven't got a clue how to do that.
I could easily knock up a bit of hardware to go on a serial port (or
similar) that could be triggered to make a noise, but these things have
already got the hardware built in and I'm looking to use what I've
P.S. "cdcontrol -f /dev/mycdrom eject" is the best I've come up with so
far for getting attention.
