Soft Off

[Phibred]

Hey,
Does any one know how to do a 'Soft Off', like how Windows and Linux 'turn off the computer automatically'. I've been searching for a bit but I can't find it in the Linux Kernel.

Thanks,

Hi

First, you should write the APM driver for your OS because APM provides API for machine power management. If you would like to do a 'Soft off' you should call APM's set_power_state() routine with the power state APM_POWER_STATE_OFF

Look at my code: http://dembol.inwestuj.com/cgi-bin/sour ... apm.c#L150

I'll have to take a good long look at that one. It just seams like a lot of overhead for just turnning the computer off though, but I see its use for laptop drivers and such.

I'll try to post my assembler version of the apm driver so people doing asm can enjoy that.
