Unlock UEFI in Sony Vaio VPCF24Q1E/B Aptio Bios EDIT: If I have posted in the wrong thread I'm sorry. Could an admin move my request accordingly? Thank you very much. Hi, I would like to have the BIOS unlocked at least with UEFI boot option. I have extracted original bios in a file (untouched BIOS.ROM, attached) and could open it with Aptio tool AMIBCP 4.53. Succeeded to enable UEFI on/off setting and flash modified ROM. UEFI setting is now shown in Bios Utility after startup, but doesn't seem to work. Is there anything I miss? Or can't UEFI be enabled on this machine? Would really appreciate a pro here having a look and confirm / modify if possible or not. Any help is truely appreciated. Best regards, belierzz
