[mythtv-users] How to Stop ACPI RTC Wakeup?

[Craig Huff]

Antani:

I have an Asus mobo.  If I recall correctly, it is an A8N-SLI Premium unit.
As you described, mine, too, has a BIOS dialog for setting the APM alarm and it
has an enable/disable control for it.  However, the ACPI alarm is apparently
separate, so when I set one, I am not setting the other one.  The same thing goes for
the enable/disable control.

The mobo works with the APM alarm.  Fedora Core 6 wants to use ACPI.  I suppose 
I could get a different Linux distro, or override the defaults to use APM instead, but
I perceive that to be a step backwards.

As far as testing out my scheme for recognizing a "magic" time in order to get the 
alarm shut off, I have to confess...The honey-do list and the nice weather conspired 
to keep me from getting much done on the computer.  I did get the modifications into
/etc/init.d/halt done, including figuring out how to test for a regex pattern (so I can 
ignore the year field in the alarm string), but I didn't get a chance to see if my system
DIDN'T wake up at midnight GMT (7pm local time).

Will advise when I find out.
