about MAINBOARD_POWER_ON_AFTER_POWER_FAIL

[zhu shi song]

I'm using i845gv based MB. The superio is w83627hf . 
I have set
MAINBOARD_POWER_ON_AFTER_POWER_FAIL=MAINBOARD_POWER_ON.Before
linux booting up, I turn off power switch, when turn
on power swith again, MB can boot again.  But when I
have booted linux successfully, I can see the console
and can login linux, at this time I turn off the power
switch and after 10secs then turn on it, MB can't boot
again.
Who have such experience to make mainboard power on
again after power fail using software solution?
tks

you can take a look at that the arima hdama code does for this. It is all 
motherboard-specific, I guess ... not sure in all cases.

The factory bios of my MB has "power fail restore"
option and I set it to enable.  The MB has the same
problem as linuxbios does.  When linux is booting
without console prompt, unplug power supply and plug
again, MB will boot automatically without press power
button.  But if linux has console prompt and I can
login the system, at this time I unplug power supply
and plug again, MB will not boot. I must press the
power button.  It seems that linux has done something
to disable the function.
