I installed windows 11 on this new chrome book. bios Coreboot is installed with version 4.22. I bought the Audio and USB4 drivers from @coolstar and I followed carefully the installation guide.
I no longer have any missing drivers. All drivers installed without any error message.
Regarding the audio driver, I only have the headphone option in the mixer, no internal speaker. But no sound at all even with an headphone.
Hey, I don’t have a solution to your Problem but I have to ask: did you get any issues while installing another OS on the CX5?
I can’t even get into recovery mode on my CX5500 and I wonder if that’s a common theme with this model.
@MrChromebox - could this be similar to the Osiris ACPI issue?
I’m a bit outdated on my firmware - but i have no issues with FELWINTER on 4.20.0 05/15/2023
@JoeM143 do you mean that you successfully installed a windows 11 OS without any missing hardwares (touchpad, sound etc…)? I planned to give another try and my idea to first downgrade the firmware to a previous version. I may try with the same version you are using 4.20. Thank you.
Hardware was all there - (I still had to find/install some drivers - but they showed up as (!) in device manager)
No Issues with Coolstar’s Touchscreen/TouchPad/Sound drivers on that particular version of coreboot
I just saw that a new firmware version was released yesterday 4.22.1 (01/16/2024). According the changelog there is a fix related to the ACPI issue.
I updated my firmware and make a fresh Windows 11 installation. Almost everything is working fine now ! I’ve got the touhscreen, the touchpad and the sound working correctly. This is really great !
The only thing missing is the numpad. I will try to find a solution for this. I had the same problem also on Linux.
