Ah.  The new motherboards that support P4C's also support ACPI.
Recent 2.4 kernels support power control through ACPI, even w/ SMP.

Your client's old motherboard wouldn't have ACPI.

If you look at /usr/src/linux/arch/i386/kernel/apm.c, you'll see
this comment.  (I'm looking at vanilla 2.4.21.)

There are some other comments in that file worth reading, too.

I don't have access to a pre-ACPI SMP motherboard anymore, so I can't
try this.  It looks, from a cursory reading of the code in that file,
like you should boot with apm=smp,power-off or
apm=smp,power-off,realmode-power-off.

If apm is a module, you can pass the right options in when you load
it.

# insmod apm power_off=1 smp=1
or
# insmod apm power_off=1 smp=1 realmode_power_off=1


 The coffee hasn't kicked in yet so I'm having trouble the English

You should do what I do.  Until you've finished your morning coffee,

Hi,

I think we have that same P4 and it works for me too.  I have a client with a dual
233.  It's never worked with that.  I was hoping that the kernel had progressed
enough to be able to power it off also.  Maybe 2.6.1?

The power off capability is in the kernel.  The right combination will turn off a
single CPU system when you type halt.  The wrong combination will either do nothing
or lock it up.  The coffee hasn't kicked in yet so I'm having trouble the English
language.

Thanks

 Has anyone gotten powerdown to work on a Dual CPU system yet?

I have it working on a hyperthreaded P4, which is sort of like a dual
CPU system.  Unfortunately, I don't know the magic incantation.  When
I installed gentoo-sources, it Just Worked[TM].

I suspect the Gentooers added a kernel patch to make it work.

 short answer: apm -s or apm -S
 
 If that doesn't work, make sure apm support is in your kernel and 
 check out the man page for apm.

And make sure apmd is running ...
