and make a CD of it. You will need to go into your BIOS and make you CD-ROM the first boot device and place the disc in the CD-ROM. The next time you turn your computer on it will boot to the CD, follow the prompts and it will over write the information on the hdd.
If you are going to give this relic away without an operating system it is pretty much worthless, especially if it is old enough to be running ME. I wouldn't even fool with the hdd, just take it out and trash it and hope that someone will take the puter for parts. Ever seen what a sawzall will do to one?
