Hi,

thanks.

Yes, it is enabled (now). But no, it didn't help.



I still have two different alarm settings.

1) The setting stored in the BIOS's ACPI section as "RTC alarm". I can
choose a time and a specific day of the month.

2) The setting stored in /proc/acpi/alarm - there I can only choose the
time, not the day.

These two settings appear to be completely independent from each other.

Also, the 2nd setting does not work. I can change it and the computer
remembers it between reboots, but the BIOS does not wake up the system
from S5. The 1st setting is able to wake up the system.

Two questions: Why are there two different settings? I thought there was
just one?

And more important to me: How can I access the 1st alarm time from
Linux? Since the BIOS lists it in its ACPI settings section, I guess
there is some way to access it through ACPI.
