Vaio aptio bios I tried editing this bios on vaio cb15 and eb46fg, i success fuly unhided some options in the boot menu-like gate a20 options, fast boot, quiet bot etc. And bios update option in advanced menu; i used the amibcp software to unhide it. In the software interface i was able to see all the options in the bios, but only the above ones were unlocked. The chipset menu, advanced menu contains processor and thermal cotrol options and many other options like switchable graphics but cannot be unlocked after flashing the bios, except the above ones.
