Revision v34	2003-08-07
__ Jubilee edition: ten years of existence of the BogoMips mini-Howto. Ratings have now reached new peaks over 6000 BogoMips
Revision somehow numbered 1.2	1999-11-12

Revision unnumbered publication. Probablye the first Linuxdoc SGML version. Highest just over 900	1999-02-08

Revision First publication	Late 1993
__ named BogoMips Information Sheet, well before the term Howto and mini-Howto were coined. Does anyone still have a copy of this text for me, please? Plain Ascii list.

The mini-howto text gives information about BogoMips, compiled from various sources such as news and e-mail. New BogoMips entries for the mini-Howto, notably for unlisted CPUs, will be highly appreciated. They can be sent by e-mail to the author Wim van Dorst
