Hello,
I have been trying in vain for the past whole week to get access to the hidden Chipset menu. I have used Backup_Tools18 to backup my bios and attached the results folder here. Please help me by unlocking the bios to get access for enabling IGPU feature since it is required for runing MAcOS Mojave which does not run properly with nvidia 540m as there are no drivers by nvidia for the same.
Thanks and Regards,
Nilesh Patel

@music2850 - Please confirm, you already tested setting User/Supervisor here at ROOT of Setup, as shown in image below?


If yes, then nothing we can do, I cannot see how it's blocked. You will have to just change the defaults directly in place with AMIBCP, for what you need changed, then reflash BIOS, and load optimized defaults to make those apply.

This is exactly what I have been trying to do since the past week reading various forums and downloading the necessary tools to mod the bios. After finally getting my hands on the right tools, I was able to change the access rights from Default to USER and also to SUPERVISOR when flashing with USER did not work. I know that the flashing has been done successfully since I backed up again in windows and checked the rom in AMIBCP which shows the changes wherever I made. But still, the effect is not reflected in the actual bios which seems to have no effect of flashing with the modified bios rom. Honestly, I am no fan of overclocking since I don't play much games. I was happy to run MacOS Sierra successfully with all hardware detected perfectly and running with full graphics acceleration, until Apple screwed things with Nvidia and tied up with AMD and that's where I felt lost to not be able to run the new MacOS Mojave with my present nvidia card. But reading the successful hackintosh builds on the similar configs like the VAIO VPCF217HG which has Intel HM65 board and 2860QM processor with 8gb RAM and 1GB Nvidia 540M graphics card which is disabled and only the INTEL HD3000 IGPU graphics have been enabled for the graphics acceleration, I started to look into possibilities for doing the same on my laptop but got the shock to find out that all the benefits of advanced menu have been locked and hidden by Sony. I do believe that it's a matter of application of right codes that need to be applied correctly unlock all the features that are present within the system. Please help me with detailed instructions for proceeding ahead step-by-step. I will follow accordingly.
