Lenovo z51-70: graphics acceleration for AMD R9 M375 GPU

Recommended Posts

File is not UEFI volume.

Also Lenovo BIOS are locked/encrypted, you won't be able to modify it.

You'll just have to use the patch bypass the DMVT Pre-Allocated check

Each Time i run the installer with every bootleg I can think and combination thereof, I can not get past the IOGraphic x43 hang.
I have the Lenovo z51 and followed every single guid, tried everything.

This laptop has switchable graphics AMD R9 and Intel HD5500

The bios is locked and allows me to select UMA graphics option and nothing else.

I can see this laptop is compatible, can you help just get to the installer at least.

Can I have a DSDT/SSDT to replace or just the EFI folder for this laptop , anyone help?
