How can I set up a boot up password. Not from the welcome screen, but in MS DOS.?

Question

I've seen on fellow employee's pc's at my office.

Answer 1

Note that not all BIOS's have this password feature, your bios may not have it in which case you won't be able to restrict access to your computer in this way.

Select USER PASSWORD and you'll be prompted to enter a password:

Answer 2

Are you thinking a BIOS password?
