My school is currently moving into a new building with new computers, so they're selling the old ones. Now, I need a live CD to automatically wipe the HDD or remove the partition table. There's no private information on the computers, so secure erasing isn't required (even though it would be nice).
I tried DBAN (Darik's Boot and Nuke) which is perfect except it doesn't beep when finished. The problem is that it would be way too much work to plug in a monitor into every computer.
Is there a software which automatically formats / removes the partition table and beeps using the console speaker when finished?
I thought about using a Linux Live CD, but how do I burn a bash script to the CD so it starts automatically?
