Hi all,

I am booting a machine that is standing in a hot environment, and
during the boot sequence, I am getting the message
"Critical temperature reached (63 C). Shutting down."
After which the system obviously shuts down.
I suppose this message is coming from ACPI. My question is however, is
there a way to control at which temperature ACPI shuts down the
system.
Can I control the behavior of ACPI? I think normally the BIOS sets
these values, but in my BIOS I am not able to change these values, so
I am wondering whether or not it is possible to override the BIOS
values, and how.

Hopefully someone is able to help me.

Do you really think that posting this again will give different answers?
You do not say how hot a "hot environment" is. You have been told that
the answer is to make sure that your cpu remians below that figure. If
the temp. outside the case is >50 degrees, you need to install air
conditioning. If it is not, then you need to install much better cooling
of the cpu. A cpu running at 63 will have a much shorter life and will
make random errors in running. That is why those limits are there.
Now how about going away and implimenting some of the suggestions,
rather than asking the identical question you asked last time.
