Now I have installed this version 47CN32WW(2.10) of bios! I think this BIOS not fully compateble for the Windows 8 and not all options include for dual graphics! When the new version of BIOS for my laptop is coming with full compatibility and functionality?

This option can't be implemented because of the nvidia optimus technology physical realization. It's because nvidia graphics card outputs all the data via intel hd3000 frame buffer. Moreover, there is actually a way to disable IGP if you use an unlocked unofficial bios, but everyone who tried it got the laptop with non-working graphics (which is kinda logical, if you think about it). Also, I'm really curious why do you need gt555m always turned on; based on my everyday experience I can say that hd3000 is good enough for all (including video players) but games/heavy graphics applications, which you can easily launch via context menu, if it's not launched automatically. If you need gt555m for linux, then you can search for so-called "bumblebee" project or wait until nvidia makes it's drivers for linux (AFAIK, they promised to do it), and there's no known way to enable optimus-based discrete GPU in mac os x.

Sadly, the option to only use the Nvidia GPU is only available to the Thinkpad line. Both Ideapad and Thinkpad support switchable graphics, but the Thinkpad's bios has the option to run on the Nvidia graphics permanently. You just have to wait for Nvidia to provide drivers that fixes your issue.
