How to enter flash mode

Hold Power + Volume Down buttons
Release Power button as soon as device vibrates

Installation

Bootloader must be unlocked
Bootloader from Android 4.0 firmware doesn't support standard bootimg format. Bootloader from Android 4.1 firmware or later should work
Installation with pmbootstrap flasher should work.

Notes

GPU acceleration with the PowerVR SGX540 is not available, but the software based pixman renderer works quite well on the device's x86 CPU.

What works:

booting pmOS with phosh
installing applications
browsing the web
display brightness adjustment
charging over USB

What doesn't

CPU-freq / CPU-idle / Powemanagement
- Device runs in full power mode and drains battery quickly

Mainline

The internal peripherals of the Intel Medfield SoC can be discovered by PCI and mostly already work with the mainline kernel drivers.

Intel MID devices where designed to boot using Intel's "Simple Firmware Interface" (SFI). The mainline implementation of SFI was quite messy and has recently been dropped in newer releases. Therefore, the second stage bootloader Petitboot is used to boot newer kernels with kexec and devicetree.
