I have a few of these motherboards being used at different locations and all require "Restore on AC/Power Loss" which is set in the BIOS. Now i have two boards with versions P1.60 and they do not have this setting in them. I then updated to the latest version of the BIOS (P2.0) which i got from the ASRock website and this version also does not have the "Restore on AC/Power Loss" function. I know that the P1.70 version definitely supports this function but i cannot find it anywhere. Where can i get it and how do i down grade to it?

ASRock tech support is taking very long to respond to me.

Hope someone else can help?

Same issue here.
We have a specific version which operates for us (1.308)
We would prefer to use 2.10 but it changes the way it communicates with the RS232 ports in addition to the AC option missing.
We also use LVDS and the screen colour is washed out older than 1.90.
We have to settle for the washed out option due to the AC issue.

I may have a copy of all of them somewhere.
