Hardware
The hardware seems to be based on the Stormlink SL-3516 SoC, which is a special-purpose chip for NAS applications based on the Faraday FA526 ARM CPU core.
Serial Port and JTAG Interface
- Serial Port (2 Volt Voltage Level!, only populated on newer boards): 2 = RXD, 3 = TXD, 5 = GND. 10 = 3.3V
- JTAG (2 Volt Voltage Level!, not populated): 1+2 = Vcc, 3 = /TRST, 5 = TDI, 7 = TMS, 9 = TCK, 13 = TDO, 15 = /RST, 4/6/8/... = GND
MAX3232 is working with 3.3V.

Firmware
Object Code
Source Code
A first 'cleaned up' version of the kernel changes (against vanilla 2.6.15) can be found at http://laforge.gnumonks.org/tmp/linux-2.6.15-icybox-gemini_v2.6.0.patch.bz2. It mostly removes all the mess introduced by CVS as well as some whitespace changes.
Bootloader
Finally made available after (allegedly) some fighting with Raidsonic. Appears to be loosely based on Redboot, but not much. Not very powerful, no telnet (so access only over serial console), but at least TFTP. Hint: If ethernet in bootloader does not work on first attempt, try pressing the reset button.
