shutdown problem

[koen de wijs]

Hello,

I have reinstalled FreeBSD. First I used 5.2.1 and now am I using 5.3. 
When I shutdown my system I have to press the power button to shutdown. 
With 5.2.1 I didn't need to do that.
I searched some time and I found this:

I found this text on this site: 
http://www.freebsd.org/releases/5.3R/relnotes-i386.html
The acpi(4) 
<http://www.FreeBSD.org/cgi/man.cgi?query=acpi&sektion=4&manpath=FreeBSD+5.3-RELEASE> 
driver will now be disabled automatically when the machine has a 
well-known broken BIOS. This behavior can be overridden by setting the 
loader tunable hint.acpi.0.disabled to 0.


Do I have to add the line /hint.acpi.0.disabled="0"   /to loader.conf??

Or do I have to add the line /hw.acpi.disable_on_poweroff="0"??

/Could anybody help me? I'm new to both FreeBSD and Unix.


Thanks Koen
