Pre-Installazione Lenovo Yoga S740 Ice Lake 14" (S740-14IIL)

[iCanaro]

per l'audio, esegui il dump del codec, clicca su FAQ che ho in firma che è spiegato come fare; mentre se clicchi su audio, viene spiegato come iniettarlo da properties

[iCanaro]

allora non ti resta che provare i voodooHDA

togli AppleALC ed inserisci nei kext in EFI VoodooHDA e AppleHDAdisabler

@TUNIN96 hai per caso info riguardo linux... lspci?

putroppo se hai provato correttamente i layout c'è poco da fare, unico mio dubbio in caso è il controller non ancora compatibile

Grazie, però gengik84 già mi disse di fare il dump con F8 e mi sono comparsi due dispositivi audio. Provammo a mettere alcid=13 e 21, valori presi dal database in boot args e non funzionava. Provammo anche metterlo nella sezione id audio di clover e nemmeno funzionò.

A quanto so, su 10th gen sono richiesti FakePCIID e FakePCIID_Intel_HDMI_Audio (per quanto "brutto" possa essere utilizzarli), almeno per ora

[Gengik84]

ok pero non parliamo di audio HDMI

[Gengik84]

servono info relative al controller audio... ID

[iCanaro]

magari prova con una distro live di linux, avrà qualcosa di simile a un pannello di controllo con una lista hardware a cui poter vedere gli ID

 

altrimenti da windows con AIDA64

Infatti parlavo di audio in generale. Su tutti i 10th gen con cui ho avuto a che fare e di cui ho avuto notizie sono state necessarie quelle sue kexts, per un gatto di controller non supportato, come anche tu hai detto. Sicuramente però ci sono alternative più eleganti 

[Gengik84]

quel kext si "allaccia" a controller di fatto già compatibili, oltre a questo salvo fork quei kext non sono aggiornati da tempo e 10th al tempo non c'era

Ho fatto alcuni dump da linux, possono essere utili per capire l'hardware che ci sta sotto, soprattutto per TB3 e le nuove usb xHCI

[Gengik84]

ma non avrei visto ID riguardo all'audio, controller etc

dopo riguardo meglio, forse mi era sfuggito

[foskvs]

lspci -nn

It seems that your audio controller is Intel Smart Sound. I'm afraid there's no way to solve the sound issue in macos, at least not yet.

[yoqueco]

TUNIN96: Did you solve the graphics acceleration issue?

[yoqueco]

I have Lenovo Yoga S740 IceLake. I managed to boot 10.15.6 with your Clover EFI. No graphics acceleration, no sound.  I guess i7-1065G7 would need some patch to get graphics acceleration.

You know anobody at Acidanthera would take care of this?

Unfortunately no

It has already been asked
they said they won't work on this
maybe in the future but not now...

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!

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!

[Sabau Ioan]

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！

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"

[Sabau Ioan]

Thank you, I will!

How can I find the Tencent QQ group  ?
