My Heavy-OperatingSystems-Tests on Yoga Book

[THE MAXIMUM POWER]

Hi Users and Devs
im writing my test results here about dual booting and other operating Systems that i have installed them on my yoga book Windows Version and i will try to explain lot of Details about this stuff
First i will share the operating Systems and Details about what work and what not on yoga book.
Ubuntu(17.10.1), PhoenixOS(2.6.2 based on Android-x86 Nougat 7.1.1), BlissOS(10.1 based on Android-x86 Oreo 8.1.0), DeepinOS (15.5): no Sound, no halo Keyboard, no Auto rotating, no sensors, no Bluetooth, only Booting, Touch Screen, Screen brightness controling and WiFi are working
Android-x86(7.1.2), Openthos(Based on Android-x86 Lolipop 5.1): nothings at all

There might be a lot of other OSs that i might Forget to mention above, but i released why some Hardware cant work like Sound, Bluetooth,......
the main Problem is the KERNEL(the kernel is a big Collection of modules and Drivers that boot up our Hardwares as soon as we enter any Operation system), some kernels 4,9.x cant boot or wifi and touch Screen cant work, all kernels 4.12.x Support booting, touch Screen and wifi, all kernels 4.15.x Support booting, touch Screen, brightness controling and wifi
the only kernel that will make other OSs work like a charm and without any missing Drivers is buildslave kernel, this kernel came pre-load with most of Lenovo Yoga series + Yoga Book (for yoga Book Android users go to about tablet and check out it), the Problem is that i dont have a 100 GB (i will explain this later) ( in 22 mar 2018 they released the second Version of the Open Source Code for Lenovo YB1-X90F/L https://pcsupport.lenovo.com/au/en/products/TABLETS/YOGA-SERIES/YOGA-BOOK/downloads/DS118515 ) also depend on my Tests the kernel is only for Android 6.0.1, not for 7.1.1
i tried to build Android x86 from sources using Yoga Book Open Source Code from Lenovo but AOSP files are Need at least 100 GB with Additional files from Android x86 abot 20 gb, unfortunatly i dont have this big size of hard disk on my SSD
Yoga Book Android and Windows versions are 99.99% contain the same hardwares (0.01% are only the Keyboard shapes but also the halo Keyboard is the same in both) thats why it make my optimistic about running Stock yb Android Rom on Windows (Windows Version of yb used same bios as yoga Windows series, but yb Android Version use the same bios as yoga Android series does and all of yoga win and Android series based on Insyde bios)
Android yoga Book System based on Android-IA Project which is from Intel to allow Android run in Intel CPUs https://01.org/android-ia as yoga Book based on cherry Trails cpu
for Android yb users you can install Windows and other OSs on your device but you will force same Bugs above and you need to buy a licence key to get Windows updates on it (i only have yb Windows so i dont know lot of informations about this)
Windows yb BIOS contains a very basic informations and options (for example there is no UEFI and legacy option, there is also no ACPI enable;disable option, cpu overclocking......)
I believe there is a way to install Android stock in yb windows, i mean through reimagie the eMMC, for more infos, visit http://en.miui.com/thread-419845-1-1.html

i will add more informations in the future:fingers-crossed: Also i might be wrong about stuff, after all its my expermints and thoughts

yoga win and Android series based on Insyde bios

Same Bios? Not really...

 

[THE MAXIMUM POWER]

Same Bios? Not really...

i didnt say same bios, i said both based on insyde

 

[jamespmi]

What makes you believe the Android YB has an Insyde Bios? Not really, and as many tests demonstrated it not even has a proper ACPI implementation.

Windows BIOS dont support ACPI implementation, that because its hidden and it need to be edited through platform.ini editor tools (inside yb win version bios), the chipset on yb win and android (so far i know both are insyde).
after all you might be correct
correct me if i was wrong

 

[jamespmi]

Windows BIOS dont support ACPI implementation

It's quite the opposite...
Beginning with Windows Vista, the operating system supports only a computer with an ACPI-compliant BIOS

Android however does not use APM or ACPI directly for power management. Android instead has its own Linux power extension (wakelock).
That's why Lenovo uses a basic BIOS on those devices..

Aha, didnt know this before, is there is a way to install fastboot mode alongside with bios ? i mean like mi pad 2, chuwi,.....

Fastboot is a Kernel feature introduced ages ago with 2.6.29 (2009) to allow asynchronous function calls (mainly to direct probe things like SCSI or libdata port scans). Nothing to do with the Bios.

Chuwi and some Chinese manufacturers use the special Insyde H20 Bios. Which the Yoga Book is not (by intention), the EEPROM is on a totally different basis.

@THE MAXIMUM POWER What is the best possible Android for playing around on the yoga book at the moment? I know, many things dont work for now, but if i want to try, would blissrom be the best way for now?

Yes, Bliss is the best one (till now)

Hey Man !
I'm not sure if you're still following this; but, I thought maybe I'd better ask if you're still keen on development of this as I'm a kernel dev and have very recently migrated to this lovely new tab. So , I thought maybe if you're still into this, maybe we could gather a team to work on I'd be happy to help with the kernel part as far as my experience beside the medical school allows me to :laugh:

Kind Regards

Hi,
You can join us on MOD EDIT: LINK REMOVED, we Need a Kernel Developer so could help us Fixing some Bugs, we are working also on a Linux that support YB

I'm afraid this doesn't seem to work. I think you people should have changed the address, mate
