Hi Scott,

Yes it works now.

Even though ASRock put this "Always Power On" feature under
"SouthBridge Configuration" menu item (mislead me very much),
 it actually controlled by SIO, NUVOTON NCT5572D.

I think the E350M1 + coreboot is perfect for me now. so nice to
get a login: in 2 seconds.

But it is really hard to get this done for a user as me. Several
times I almost give up.

coreboot is really really too hard for those users who just want
 to run a NAS / BT server in his/her living room.

Many thanks for your help,
