The Fujitsu Siemens S100 like various other early models in the Futro range is based on a 17cm x 17cm Mini-ITX mainboard. The board is designated as a D2456 but I haven't been able to find any data on it. In a quick search I couldn't find any historical data on the S100 on Fujitsu's site.
It looks like the product was announced in July 2009 and at launch was fitted with a VIA Eden 500MHz CPU . A datasheet I found on the S100 was created in January 2010 and also refers to the CPU being a VIA Eden 500 ULV (500MHz). However my example is fitted with a VIA Eden 1GHz CPU. I don't know when the transition occurred or how you can distinguish the two models.
I did find a Fujitsu Road Map (dated December 2010) which showed the S100 reaching EOL at the end of Q1 2011 with the follow-on product being the helpfully named "Successor of FUTRO S100". Maybe the 1GHz upgrade was the successor? There is a label on the top of the PS/2 sockets on my S100 that carries a 2012 date (See right) that kind of supports this theory.
The basic specs for the S100 are:
500MHz or 1GHz
1GB (max 2GB?)
VX800 (Chrome 9)
32 bit colors, 1920 x 1440 / 85 Hz
4 x USB2.0
Kybd & mouse
Coax 5.5mm x 2.1mm
Dimensions H x W x D (mm) 185 x 42 x 185
My S100 came without any flash memory. The datasheet indicates it would be running the Linux based OS eLux RL, or eLux RL lite.
The S100 runs off an external 12V supply. The connector is a standard 5.5mm x 2.1mm coax plug. The PSU that came with it was a Liteon 12V 3.33A unit.
The S100 is fitted with a Via Eden CPU clocked at 1GHz.

This is fairly straight forward. First remove the two screws on the back panel at the top. The front panel/top panel can then be gently slid forward. I found it to be a snug fit and it needed a bit of gentle encouragement to move.
The motherboard is a Mini-ITX D2456.
Flash: The board is fitted with a Compact Flash socket so increasing the size of the flash is straight forward. As you can see in the photo my S100 came without any CF card. I plugged in a 1GB CF card and it worked without any problems.
RAM: The board has a single SODIMM socket for PC2/DDR2 memory. Mine came fitted with a Samsung part - 1GB 2Rx16 PC2-6400S-666-12-A3. (The datasheet says 1GB/DDR2/800MHz).
I tried out a 2GB part: HYS64T256020EDL-2 5C2 (2GB 2Rx8 PC2-6400S-666-12-F0) which worked perfectly.
USB: There are two USB 2.0 sockets on the front and two on the rear.
Click on the photograph to get a more detailed view of the circuit board.
By the battery is JP14 which is a usual 'clear CMOS' jumper. There is also a connector, LPC1, (name implies an Low-Pin-Count bus interface) and an unpopulated connector SPI_CN.
There are two unpopulated SATA sockets on the board. I note that, as is usually the case, the capacitors in the data lines are also missing.
