BIOS AMI 5.11 of the tablet system board

[tumanovalex]

I bought a Chinese tablet with this bios. There's a sea of settings in which I do not understand much. But I would like to understand and adjust the tablet. A detailed description for the tablet on the manufacturer's website did not find the following: http://en.51cube.com/Product/3615044933.html. How do I act? Write manually all BIOS parameters and search for their description on the Internet? Maybe there is another way?
