RKM MK 802 IV LE User manual
Welcome!
Thanks for purchasing one of the most cutting edge mini computing devices available today,
the MK802IV LE.
The MK802IV LE is a powerful quad core Linux mini computer which runs a version of
Ubuntu Linux called Picuntu, this is a specially designed desktop OS for devices with ARM
processors. If you are familiar with Linux you should have no problem setting it up and using
the device. If you are new to Linux then this device is a great platform for learning about
Linux on ARM architecture and exploring the many possibilities it brings to modern
computing. This user manual takes you through the basics of setting up the device for the
first time and basic usage.
Please note this product is intended for early adopters of ARM Linux platforms and
developers, many of the features are still under development so certain things might not
behave as expected! This device does not support full hardware accelerated video playback,
however up to 720p video playback is possible due to the high performance CPU cores
which allow software decoding and playback. Development is happening on a daily basis and
we openly invite users to get on board to help with improving this affordable, open source
computer platform. Please join our forum at http://www.rikomagic.co.uk/forum to keep
updated on the latest developments.
