HDD on demand wiping

Ok, its been a long time since I've done this and my scripting is very bad now days. So I thought I would come here and ask for help. Back in the day I had a script that I could run, that would in turn reboot the computer and run a program like DBN (Darik's Boot and Nuke). I was wondering if anyone has something similar or can help me out here. I've been working for this company for a while and have my own computer there. I get the feeling my days are numbers and I don't want any of my files going to them. So, if they day comes I want to be able to well, hit a keyboard sequence and wipe the HDD.

Thanks for any help

I remember something like that a long time ago, but I was unable to find it.
But you have to be careful, nowdays you can get in trouble for deleting a company's computer, usually their end user agreement states that nfo & files you've created belongs to them.
You could create a DBAN CD or floppy.. pop it on the drive and C-A-D.
