Pentium FDIV bug

The Pentium FDIV bug was a bug in Intel's original Pentium floating point unit. Certain floating point division operations performed with these processors would produce incorrect results. According to Intel, there were a few missing entries in the lookup table used by the divide operation algorithm.

The presence of the bug can be checked manually by performing the following calculation in nearly any application, including the Windows calculator:

4195835.0/3145727.0 = 1.333 820 449 136 241 000 (Correct value)
4195835.0/3145727.0 = 1.333 739 068 902 037 589 (Flawed Pentium)

Eth ithin Mr. Linus kiyanne ewa echchara gaanak nae kiyala.

However, Linux founder Linus Torvalds posted a message on the RWT Web site noting the bugs were "totally insignificant".

Weird thing is that it says "This update does not apply to your system".
Maybe that patch is included in the Reliability and Performance update (beta) that I installed, and is already present in my Vista installation.

I don't think so. It is coming through Windows Update and it is only 40 odd MB in size. (see first news item of http://www.thehotfix.net/)

Maybe what you are referring to is Windows Vista Service Pack 1 Hotfix Preview shown here: http://vistasp1.net/

P.S.
According to the 3rd news item at http://www.thehotfix.net/, it seems what was leaked as performance & reliability pack and compatibility & reliability pack are what will be available in windows update.
