## Installation (legacy mode)

Installation made with the 2015_12_01 image, which includes the kernel version 4.2.5.

### BIOS configuration

- Touchpad: Basic
- Boot Mode: Legacy
- Boot priority order: the eMMC block device needs to have a lower boot priority than the USB bootable device.

Then save and exit.

### Kernel parameters

Without these options, the installation image will not load at all:

- edd=off
- noapic

Without this option, the kernel will automatically load the pinctrl_cherryview module which is incompatible with the Acer Cloudbook:

- modprobe.blacklist=pinctrl_cherryview

If that module gets loaded, multiple ACPI issues will arise; systemd-udevd will freeze and report multiple errors.

Therefore these parameters needs to be added at the end of the kernel parameters' line of the boot launcher:

    linux /vmlinuz-linux ... edd=off noapic modprobe.blacklist=pinctrl_cherryview

### Installation

- Everything should function without any issues thanks to the previous kernel parameters, proceed to install the image as normal.
  - The module for the wireless NIC is included with the kernel, so Wi-Fi works out of the box.
- Do not forget to add edd=off noapic to the kernel parameters of the boot launcher's configuration file and also to blacklist the pinctrl_cherryview module.

See: Kernel modules#Blacklisting

## Installation (UEFI mode)

No additional kernel parameters are needed.

### BIOS configuration

- Touchpad: Basic
- Boot Mode: UEFI
- Boot priority order: the eMMC block device needs to have a lower boot priority than the USB bootable device.
- Secure Boot: Disabled, or use BIOS menu to trust the Arch ISO bootloader.

Then save and exit.

## Troubleshooting

### GDM

If Gnome/GDM is installed and started, the login page will flicker up-to the point that it becomes nonfunctional. See GDM#Use Xorg backend.

### High load average on idle

The kernel module rtsx_usb_ms is loaded at boot time yet is non-functional (the kernel thread associated to the module when inspecting with top is a zombified process) and unnecessary for the system to function. The module can safely be blacklisted.

### Bluetooth

At least in AO1-431-C8G8 bluetooth device is deactivated via RF-kill by default. After activating it works flawlessly with bluez.
