Most modern motherboards supports the timer based
automatic power on
via BIOS settings. With linuxbios this is not(?) possible. There is a program
for linux, called nvram-wakeup, to set the wakeup time in nvram or rtc. But
especially for the K7SEM or EPIA boards a reboot is needed after it, so the
wakeup settings can take effect.
Does anyone know what the BIOS is doing what linuxbios does not?
Perhaps it can be done in a program?
I believe it is just a matter of programming some real-time clock registers
so an alarm will go off at a specified time, and setting up the
appropriate southbridge or superio bits so that the board will wake up
when the alarm is triggered. I doubt it even requires BIOS support at
all. Though that can't hurt.
