Installation

Firmware Update

If the machine does not boot after the firmware update, make sure that the battery is fully charged, could save you some time.

Launching the LiveCD

Generic instructions, as well as downloads are available at Adam Williamson's Fedlet website.

Note that the internal SD card reader is not bootable, and that the Onda's firmware will not see the USB drive by default. For that you will need to:

Press "Del" at startup (when you see the Onda logo)
Then select the "Save & Exit" section and activate the "Launch EFI Shell from filesystem device" menu item
At the EFI shell, type:

Shell> map

you should see a number of items, one of them will be tagged as "Removable HardDisk" with the "fsX" alias (fs3 with the default Windows install)
Type to change the current drive:

Shell> fs3:

Followed by:

Shell> \EFI\BOOT\BOOTIA32.efi

Voila, you're booting the live CD. Proceed as per usual.

Note the necessary changes in the firmware menu below for the internal MMC before starting the installation

If the machine hangs randomly when booted from the Live USB disk, make sure that the disk is plugged into a powered USB hub, even if it's the only device plugged in directly to the USB OTG port.
