Then first of all we would need to reduce modes pointers. Keeping mode pointer in every state struct is/was useless. About introduced solution (keeping struct and memcpy to it) I introduced that to make hacking requested mode possible. Info from AtomBIOS about PCIE lanes seem to be useless (I've never seen anything else than 16) so I want to hack found mode for DPMS OFF to use 1 PCIE lane. Without keeping whole struct it would be impossible without overwriting original entry in array and loosing original info. -- Rafał ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
