Installing Ubuntu 10.04 in the fitpc2i

was as easy as installing Ubuntu in any

other computer. Use a bootable USB image or attach an external USB-CD Drive.

Just make sure that you choose a 32 bits image as the Atom CPU runs 32 bits.

In our laboratory we have tested the Fitpc2i with a Intel(R) Atom(TM) CPU Z550@

2.00GHz

and 2 GB of RAM. The unit runs at 35-40 C when idle so make sure that

you do not forget it under a pile of books as I did. There are at least two revisions

of this hardware but the process of installation should be the same.

CompuLab, the company behind the FiTVT provides support for Linux Mint as the

hardware seems to be targeted to those that want to run a nice multimedia

station at home (i.e. stream audio/video obtained from good friends to a

television). We warned that the unit does not come with VGA output and has a DVI

Digital output up to 1920 x 1200 through HDMI connector instead, so you will

need a LCD/TV screen with HDMI or DVI input to connect the FitPC.

There are two useful accessories that you can consider, an analog VGA converter

is powered from the DVI port and requires no external power source and the

external heat-sink.

The main glitch in the installation process is that the stock kernel that ships with

Ubuntu 10.04 has buggy R8169 network driver that has broken auto-negotation.

In my case, only one of the interfaces was able to negotiate the speed, while the

other interface required the ethtool to force the speed to 10 Mbps. Fixing the

speed of the second card to 10 Mbps was the only solution so you can upgrade

your kernel.

Once you upgrade the kernel from version 2.6.32-33 to 2.6.32-38 you will discover

that the DADHI drivers that are used Asterisk are now broken and you will have to

rebuild them. The DADHI drivers depend on kernel version (i.e. wrong symbols). In

a nutshell, in order to get the network cards to work you will have to (1) upgrade

your kernel and (2) rebuild DADHI Asterisk drivers.

The default linux kernel uses the PAE extensions that allows to run 32bits with lots

of RAM.
