After experiencing difficulties with his computer, a poor, incognizant user called the system makers technical support line for assistance:

Technician: Hello. How can I help you today?

Customer: Theres smoke coming from the power supply on my computer.

Tech: Sounds like you need a new power supply.

Cust: No, I dont! I just need to change the startup files.

Tech: Sir, what you described is a faulty power supply. You need to replace it.

Cust: No way! Someone told me that I just had to change the system startup files to fix the problem! All I need is for you to tell me the right command.

For the next ten minutes, in spite of the technicians efforts to explain the problem and its solution, the customer adamantly insisted he was right. So, in frustration, the technician responded…

Tech: Im sorry. We dont normally tell our customers this, but theres an undocumented DOS command that will fix the problem.

Cust: I knew it!

Tech: Just add the line LOAD NOSMOKE.COM at the end of the CONFIG.SYS file and everything should work fine. Let me know how it goes.

About ten minutes later, the technician received a call back from the customer…

Cust: It didnt work. The power supply is still smoking!

Tech: Well, what version of DOS are you using?

Cust: MS-DOS 6.22.

Tech: Well, thats your problem. That version of DOS doesnt include NOSMOKE. Youll need to contact Microsoft and ask them for a patch. Let me know how it all works out.

When nearly an hour had passed, the phone rang again…

Cust: I need a new power supply.

Tech: Really? How did you come to that conclusion?

Cust: Well, I called Microsoft and told the technician what you had said, and he started asking me questions about the make of the power supply.

Tech: What did he tell you?

Cust: He said my power supply isnt compatible with NOSMOKE.
