Can you please include the BIOS settings you changed in the Product desciption as well?

sbarbara commented

Hi

Thanks for your reply... I already saw that. What I meant was for example Secure Boot, VT-d, TPM etc... What should those settings be? From the BIOS accessed by pressing F2. Hope it is clearer now.

Thanks

Here's everything I know about this model. (excerpt from my notes)
You can translate and read it yourself.

U938 BIOS 设置

特殊键

  2. 分别输入 3hqgo3 回车，jqw534 回车，0qww294e 回车
  3. 记录下弹窗出现的代码，访问 bios-pw.org 进行解密

调整设置

最佳设置

先逐项按需配置，再使用 setup_var.efi 调整。

# CFG Lock
setup_var.efi CpuSetup:0x3C=0x00

# Package Power Limit MSR Lock
setup_var.efi CpuSetup:0x29=0x00

# Above 4GB MMIO BIOS assignment
setup_var.efi SaSetup:0xE4=0x01

# Intel(R) SGX
setup_var.efi CpuSetup:0xF2=0x00

# DVMT Pre-Allocated
setup_var.efi SaSetup:0xDF=0x02

调整 MSR

把以下命令编写成脚本并添加到计划任务，触发器设置如下：

  1. 设置为 登录时, 延迟任务时间 10 秒
  2. 设置为 发生事件时, 源为 Kernel-Power 并设置从睡眠唤醒的事件 ID, 延迟任务时间 10 秒
  3. 设置为 发生事件时, 源为 Kernel-Power 并设置电源更改的事件 ID, 延迟任务时间 10 秒

Hi again.

I managed to set the commands in Opencore openshell and Osx Sonoma booted and is working like a charm. WIFI and bluetooth working out of the box?????!!!! Incredible man... Great job with the EFI setup, I am truly amazed. Can't believe how much the laptop is great for Osx.

One thing I noticed though after the commands issued is that I cannot get into the BIOS of the laptop. Although I think it is in the background it is not showing up on screen Same for the logs while OSX is booting. Then after some time the apple logo appears and OSX login is shown. It is not related to verbose mode as I did not change anything related to that.

Try after shutting down completely, quickly click F2 when turning on the computer.

sbarbara commented

Already did that but nothing is displayed even though I am sure I am in the BIOS... Strange behavior... Can I somehow revert the commands I issued from Open Shell?

Not sure, I've never encountered this problem.
