Hi Gambit,
Thank you for considering Sony Community!
We do not recommend installing a different operating system to your Vaio laptop. We only have Windows drivers for this unit: https://esupport.sony.com/US/p/model-home.pl?mdl=VPCEH3QFX&template_id=1®ion_id=1&tab=download#/downloadTab.
For further assistance regarding your concern, please contact the Sony offices/Sony representative offices nearest to your place of residence in Asia Pacific region http://www.sony-asia.com/countryselector.html?hpid=countryselector:AsiaPacific. Due to proximity, they are in a better position to respond to your questions or concerns.
Regards,
Vincent
