Flash Bios Help! :)

Hey,

Trying to flash my Bios but i got a few problems.. I got a custom laptop so i cant go to a website like asus or something... When I run CPU-Z it says my motherboard is Notebook W65-67SF and my BIOS is American Megatrends Inc 1.03.03

At this moment my BIOS is very limited with options. I want/need more options.

Whats the best thing to do now? I hope someone can help me...
