Description
Back in 1994, a bug was discovered in a certain number of Intel
Pentium processors in which certain mathematical operations would
yield an incorrect result. The bug was fixed in all Pentium
processors produced after 1994. In the unlikely event that
you’re running Windows XP on a computer that old,
open a command prompt and type pentnt to test your
processor for the bug.
