Comment 1 Arjan van de Ven 2002-02-08 21:55:23 UTC

Does it work if you type 
"nomce" 
on the syslinux prompt?

"MCE" is self-diagnosis. whoever it seems that some board designer at compaq
made a habbit of wiring the MCE pin of the cpu to the 5V line ;(
nomce disables the checks.

Many thanks install now proceeds

Old compaq docs confirmed some early compaqs reported MCE incorrectly. Current
product treats pentium MCE as unreliable
