my github address！Urgent problems! The screen becomes blurred at startup

YOGA-S740

I hope you can make more progress, especially the ACPI hot patch. I don’t know much about it, but you can make it first, and then it will be compatible with ice lake.
, Such as the touchpad, although it is not compatible now, we can do the hot patch first, as well as the button mapping and so on! I really can't do this, I hope you can do it!

The sleep seems to be successful, but it seems to be unsuccessful. My test is to plug in the power and there is no way, and further customization is needed! And this may require a graphics card driver to achieve!

Thanks for the tip. Obviously you are on a higher level. By the way, TUNNING's EFI is my work, I gave it to him. Enjoy!!!!

Do you have any new progress?If you are proficient in hot patches, I hope you can help make an adaptation!

08-05-s740-OC. The sound card is normal（really fixed）， the frequency conversion should be normal, the time is normal, with wifi driver, Bluetooth driver, graphics card is not driven, and the touchpad is not working！

At the same time, the wifi driver panel is attached! Just put it in the APP folder

I tried this efi folder, but I can't boot into system. I uploaded a video booting from this efi folder.

 

 

I tried your efi folder and I can boot into system with your same issues. 

 

Your problem should be that it is not the same device as ours. Try to change the platform id (should not be left or right) or MMIO. I don't know. There are many situations like this, and I am not sure!

s740-0penCore. Applying the Korean efi can enter the system, the sound card shows no sound, the time problem is changed to oc fixed, the graphics card has no driver，But there seems to be hope! the existing problem is mainly the adaptation of the ACPI table(I'm not good at this), and the repair of the sound card. It is time to mobilize!20200805-s740-OpenCore,need fix ACPI pach.zip

Are you making any progress? We seem to have to move to oc! A Korean seems to be driving a graphics card. His graphics card is G4 

https://x86.co.kr/mymac/4919509  This is his post. We discussed it for a day yesterday without knowing how he drives it!

Hey guys, maybe audio will work with this applealc kext version.

no working ！I have tried it a long time ago, and currently only fack sound cards can make sound! And there are still problems! When driving the sound card according to the usual steps, there is only a driver but no sound. Some people say it is an IRQ problem, but I tried to use this to counterfeit the repair, but it failed!SSDT-HPET_RTC_TIMR-fix.zip

but！The nodes of s740 and c740 codec are the same. If theHPET IRQ problem is solved, it should be possible to try to drive with ID=61, no need to do sound card adaptation!

How can I find the Tencent QQ group  ?

How to use Google search and join, maybe you can get more information!

Just now, Sabau Ioan said:

You're right, the display is 4k. Is there a method to make it work?

So far, there is no way! Unless "whatevergreen" is updated! I have switched to Linux (elementary os) in the past twenty days, and the efi I uploaded is all my progress!

Maybe you can also join our 10nm chat! In the Tencent QQ group "1071663502"

Try this Clover. It is forCLOVER.zip Yoga S740. It works on mine  but the graphic card  has only 31 Mb VRAM. How did you changed your CFG lock and DVMT ? Do you have a modded BIOS?

31M is because your screen is 4K (UHD), I will upload the CFG lock and DVMT modification method! Even if you upgrade the BIOS, if you do not choose to restore the default configuration, it will not be affected！

Please load your complete configuration 

I don’t know what you mean. My EFI has been shared in my reply! You can check it yourself! Hope you have more progress!

Repost my own tonymacx86 post

After referring to the efi of TUNIN96, I entered the system desktop!
Now the completion is very low!
ok: sound card(Sound card microphone popping sound and ten seconds before playing card), frequency conversion, Bluetooth;
no: graphics card, touchpad, and so on!
There is an urgent need to solve the problem: the time is abnormal and the rotation is fast! Time jumps two seconds or more in one second!
Attach EFI!
Hope that everyone who is the same Lenovo and the same machine we can complete the adaptation of this machine!
