A guy rings tech support to report that his computer is faulty.
Tech: What's the problem?
User: There is smoke coming out of the power supply.
Tech: You'll need a new power supply.
User: No, I don't! I just need to change the startup files.
Tech: Sir, the power supply is faulty. You'll need to replace it.
User: No way! Someone told me that I just needed to change the startup files and it will fix the problem! All I need is for you to tell me the command.
Ten minutes later, the User is still adamant that they are right. The tech is frustrated and fed up.
Tech: Sorry, Sir. We don't normally tell our customers this, but there is an undocumented DOS command that will fix the problem.
User: I knew it!
Tech: Just add the line LOAD NOSMOKE.COM at the end of the CONFIG.SYS. Let me know how it goes.
Ten minutes later.
User: It didn't work. The power supply is still smoking.
Tech: Well, what version of DOS are you using?
User: MS-DOS 6.22.
Tech: That's your problem there. That version of DOS didn't come with NOSMOKE. Contact Microsoft and ask them for a patch that will give you the file. Let me know how it goes.
One hour later.
User: I need a new power supply.
Tech: How did you come to that conclusion?
User: Well, I rang Microsoft and told him about what you said, and he started asking questions about the make of power supply.
Tech: Then what did he say?
User: He told me that my power supply isn't compatible with NOSMOKE
