I almost do not know Linux, but I managed to run WiFi and Bluetooth.
From the original Android I downloaded the firmware files and used them in Ubuntu, restarted and it works! 🙂
I attach the files in the attachment, in one picture is shown in the terminal where to copy them under what name.
I'm still trying to play with UEFI Setup and find out what's preventing Windows from running, but I'm a UEFI beginner, so I don't know if I'm going to succeed.
WiFi + BT.zip
Wifi working now in android x86. Doesn't work on live CD but works fine when installed.
Just need to get touch screen and drivers working now and it'd almost be a usable tablet again. Well, other than the fact it only boots into safe mode.
In the 10th partition, I remember the Mac's WiFi address is hidden.
Is there a Broadcom connected via SDIO if I'm not mistaken but needs to upload a Mac address and then it should work smoothly, but we haven't tried it yet, there's no time for it.
Touching, it should just be enough to load the driver, I don't remember what chip is used there, but it shouldn't be a problem to get in touch. I think it will be connected via I2C.
