My sister's Vaio SVF1421 laptop come with Windows 8 Single Language. But she would like to install 7 OEM. However, I found that BIOS of the laptop has only SLIC OA 3.0 and it is not supported to activate 7 OEM. - The question is BIOS of the laptop really has only SLIC OA 3.0 or it also have hidden SLIC 2.1? - If it has hidden SLIC 2.1 then how to unlock the SLIC table?
