Just been chaseing up some post install loose ends, one of which was
getting the 'automatic power off on halt' to work...
The steps required turned out to be:
a. apt-get install apm
b. echo apm >>/etc/modules
c. echo 'options apm power_off=1' >/etc/modprobe.d/apm
which seems to have done the trick nicely.
However I am a little concerned about the messages produced when apm
is loaded:
apm: BIOS version 1.2 Flags 0x03 (Driver version 1.16ac)
apm: disabled - APM is not SMP safe (power off active).
This is a SMP motherboard with two cpu's installed:
Intel MultiProcessor Specification v1.1
Virtual Wire compatibility mode.
OEM ID: INTEL Product ID: 440GX APIC at: 0xFEE00000
Processor #0 6:8 APIC version 17
Processor #1 6:8 APIC version 17
I/O APIC #2 Version 17 at 0xFEC00000.
Enabling APIC mode: Flat. Using 1 I/O APICs
Processors: 2
So is the message about apm being disabled lying - it is doing something
as it is enabling my auto power off, and /proc/apm appears showing:
penemunde:/etc# cat /proc/apm
1.16ac 1.2 0x03 0xff 0xff 0xff -1% -1 ?
I have skimmed through the apm source, at it looks to me like it is just
that the message is a listtle misleading and that the power off part
of apm is safe with SMP, and the unsafe bits are disabled.
I think this is right, but thought it worth mentioning as it seems like
something that should be in an Etch FAQ..
