	MorphOS for EFIKA posted by Matthias Muench on 5th August 2008 Finally, after 2 years of the announcement MorphOS appears for the EFIKA. But I gave the EFIKA already in January to another developer because I was not happy with the hardware lock registration MorphOS uses and I had no use as a Linux box. So thats it for me. This was the final case I used for the EFIKA. I used Debian GNU Linux 4.0 but wasn't very happy with. 128 MB were definetly not enough so everything was a bit slow. [Permalink]

	EFIKA in summary posted by Matthias Muench on 26th June 2007 Since MorphOS is still not available for EFIKA and I often get the question what the are the pros and cons of EFIKA I will write some short summary: + small size, can fit nearly everywhere + low power, takes about 10 watt for a full system + low cost, for $99 you can't get something similar - can handle only 1 IDE drive, no SATA ports - only USB1.1, no USB2.0 ports - no second Ethernet port, useful for router or proxy - RAM is soldered, not expandable via socket - no standard form factor, you can't use default cases - no onboard gfx EFIKA is a nice system for many fields but lacks some features which makes it uninteresting for a small and light desktop computer.

	Stream Benchmarks posted by Matthias Muench on 10th April 2007 My next step was to do some benchmarks under Linux to check the RAM performance. I used the Stream test against Pegasos and Sam440ep board.

	EFIKA cases posted by Matthias Muench on 10th April 2007 After receiving the EFIKA I started to setup a system and installed Linux. I tested 2 cases and did some photos of the conversions. [Permalink]
