Q&A: The Pentium FDIV Bug
Q: How many Pentium designers does it take to screw in a light bulb?
A: 1.99904274017, but that's close enough for non-technical people.
Q: What do you get when you cross a Pentium PC with a research grant?
A: A mad scientist.
Q: What's another name for the "Intel Inside" sticker they put on
A: The warning label.
Q: What do you call a series of FDIV instructions on a Pentium?
A1: Successive approximations.
A2: A random number generator.
A3: Or a really expensive space heater.
Q: Complete the following word analogy: Add is to Subtract as Multiply
A: Number 4.
- On a Pentium, all of the above
Q: What algorithm did Intel use in the Pentium's floating point divider?
A: "Life is like a box of chocolates." (Source: F. Gump of Intel)
Q: Why didn't Intel call the Pentium the 586?
A: Because they added 486 and 100 on the first Pentium and got
Q: According to Intel, the Pentium conforms to the IEEE standards 754
and 854 for floating point arithmetic. If you fly in aircraft
designed using a Pentium, what is the correct pronunciation of "IEEE"?
Q: How do you share 50 Pentiums amongst 50 users?
A: You can't.
A: Throw one Pentium away, and then give one to each user.
Q: What new instruction are Intel working on?
A: BDV - Branch Davidian.
Q: What is Intel's follow-on to the Pentium?
Q: What does the element Pentium decay into?
A: Inert silicon with the emission of a press release.
Q: What's the difference between an Intel Pentium and a Ford Pinto?
A: None, really: the flaw and the company's attitude about it really burn you.
Q: What's the difference between a Thalidomide pill and a Pentium chip?
A: One causes deformities on the outside, and the other is deformed on the
Q: How do you use a Pentium machine so that you get correct calculations?
A: Steady your hands against it so you are not shaking your slide ruler.
Q: What's the difference between Intel's executives and Richard Nixon?
A: Even Nixon had ethics once in a while.
You are at a remote research station. If you had a choice between a bag
full of Pentium chips and a bag full of nacho chips, which would you
The nacho chips. Both bags will give you heartburn, but at least the
nachos would help you survive.
You have heartburn because of your Pentium microcomputer. How do you

No Pentium jokes please!
I have a 100 MHz Pentium based computer and would like to point out that
- despite of recent negative reports - this machine is highly rel!##@$%%%&&^\^^^
