Lenovo Y50-70 UHD need DVMT-prealloc 128 mb

[KShak]

I am having trouble booting into the bios. The novo button does not do anything and pressing F2 does nothing. This is after downgrading to 1.13 and executing the rest of the instructions in the README.

Here is a Trick . . .

No worries, I just found out if I hold F2 then power on like normal,
it does the same as the Novo button, but thanks for your help!

Dear @BDMaster;
according to this guide,
For installing hackintosh on my lenovo y50-70 UHD, need a patched bios so that I can change DVMT-prealloc BIOS setting to 128MB.
uh... I recently uses the lenovo bios tool to update my bios to version 9ecn43ww (updated from 2.01 to 3.03)
One more thing is that how can I install the received bios patch on my laptop?
any help would be appreciated.

here are my results:

Then how could I flash it over the sleep bug? cause I'm on mac right now and cannot install a windows OS.
Is it possible to flash it using a bootable usb flash containing Dos as guides like this ?or no?

Hi there !

I am really in need of extending my DVMT-preallocated memory to 128 MB in order to install Hackintosh on my Lenovo Y50-70 having an UHD screen.


Machine name: Lenovo Y50-70 UHD version
CPU: Intel Core i7 4710HQ
Samsung SSD 512 GB
GTX 860M

BIOS version was downgraded to 1.14 from 3.03 today.

Would really appreciate if you modify my BIOS with 128 MB DVMT Preallocated memory and if you can to enable advanced settings menu.

I attached DSDT.bin dumped with RW 1.6.8.1 and also AIDA64 full report txt.

Thank you !
