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

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

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.

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.
