Each time the PC boots and I pop in the Debian DVD into the DVD tray, it emits a blaring sound. I know the sound is emitting from the speaker inside of the PC but short of pulling it out or disable it via the BIOS, can I disable it in any other way as no sounds are heard when I boot with say Fedora, Ubuntu, etc?

The pc speaker is usually being handled by a kernel module named pcspkr. To unload this module manually you can try

modprobe -r pcspkr

Of course, you need to do it as root (or through sudo).

To make this persistent, you could add the line

blacklist pcspkr

to a file in /etc/modprobe.d/

Disabling the pc speaker from BIOS is probably overkill, since those BIOS beeps are a valuable source of information when debugging hardware issues.

Thanks. How do I unload the module before the Debian installation menu is presented as the sound emitted occurs as soon as the DVD boots? – PeanutsMonkey Aug 31 '11 at 0:48
