Description Alan Cox 2003-05-07 11:37:18 UTC
Description of problem:

The explanation for the use of "nomce" on compaq systems is wrong. The technical
description 
is apparently "Compaq connected the external pin to the wrong value". I guess
the polite/end user summary is 

"Early Compaq pentium machines may need this option because they do not support
processor error checking correctly."

Also btw

"A few other laptops - notably those using the Radeon IGP chipset may need this
option"

Comment 1 Sandra Moore 2003-05-08 14:05:39 UTC
Thanks again for the feedback. I've edited the nomce boot option to read as follows:

This command disables self-diagnosis checks performed on the CPU. The kernel
enables self-diagnosis on the CPU by default (called 'Machine Check Exception').
Early Compaq Pentium systems may need this option as they do not support
processor error checking correctly. A few other laptops, notably those using 
the Radeon IGP chipset, may also need this option.

This correction will appear in the next release of the documentation.

Cheers!
