[Guide] Lenovo Y50 (UHD or 1080p) using Clover UEFI (10.11)

Status
Not open for further replies.
@masterscarhead1 Thanks for quick response and clarification. I understand that my BIOS version is not compatible.

I would like to keep my BIOS version if possible, since it fixes few issues with internal fan and sleep issues on windows which I experienced with older version.

To do that I need to patch DVMT-prealloc with UEFI shell, according to the guide.
The instructions point to http://www.tonymacx86.com/yosemite-...d-1080p-using-clover-uefi-19.html#post1050617

However that page doesn't redirect me to correct post. It seems permalinks are broken currently for me for tonymacx86.com.

Can someone tell me exact post number so that I can find it?

Eventually, is it possible to restore BIOS version 1.14 and where can I find a link to installer?

I was also very sceptical downgrading my laptop's BIOS. Good news is that you don't have to do it PERMANENTLY. You can downgrade your BIOS to 1.14, patch DVMT-prealloc and then, install again the 3.03 BIOS. Everything works now perfectly in Windows as well as in MacOS. The new adjustment remains unchanged when you upgrade your BIOS to 3.03!!!

That link is to patch with downgraded BIOS, which is what I suggest. Please read carefully. I fear you may brick your computer if you do something that you don't fully understand.

RehabMan said:
But you can also use a UEFI shell to adjust the DVMT-prealloc and avoid using a patched BIOS. Lately this is commonly done on Broadwell machines. Check at the links from the FAQ: http://www.tonymacx86.com/el-capita...faq-read-first-laptop-frequent-questions.html.

This is the link for UEFI

@biofotos That's really great news, where can I find a link to instructions on how to do that? How did you do this?

With the forum software change, evidently many links broken.
 
Hello there,
so my problem is sometimes I'm losing audio and it's necessary to change the volume down and up for few times and then audio is back. But it doesn't work always - sometimes the only way it's to logout or put for a second jack 3.5 and put it out.
I'm attaching the files

Does it happen with a fresh install? (may be something you installed).

Note several things added (you might try removing):
- VirtualBox
- NoSleep
- Android File Transfer (see FAQ, will break bluetooth/BrcmPatchRAM)

I think it was from the beginning, but I tried to delete this three apps. Let you know soon.
 
Hello again,

I was able to successfully change prealloc setting to 0x4.

What I did is:
Download 1.14 bios.
Change bios installer flag in .ini file to allow downgrading.
Downgraded to 1.14.
Set variable for prealloc to 0x4 from 0x1 via uefi boot loader on usb pendrive.
Upgrade back to bios 3.03.

> OSX screen flickering is gone.
> Bios version is 3.03 again.

However new problem appeared:

When running osx screen randomly goes black after 30-60 seconds, I have to use Fn+F1, alt combo to wake it up.

Has anyone experienced this problem before?
Is it easy to fix?

EDIT: Fixed by disabling legacy boot.

Thanks for your help guys, looks like all issues are resolved now and I can fully enjoy my hackintosh y50-70 UHD model :)

The property name is: USBMouseStopsTrackpad (set to 1).

Many clues for configuration in the Info.plist.

The command doesn't work (with or without sudo). It shows :
Code: 
ioio: setting property 'ApplePS2SynapticsTouchPad:USBMouseStopsTrackpad' as number to 1 (0x1)
But touchpad is still not disabled. I wonder whether it has to do with the options being removed in syspref
