This box is a cheap (in germany) kirkwood based nas which can used as hardware for IPFire. But you need to add a serial console. http://simon.baatz.info/raidsonic-icy-box-ib-nas6210-my-new-sheevaplug/
CPU: Marvell Feroceon 1.2 GHz ARMv5te RAM: 256MB 16bit DDR2 @800 Storage: 1 (6210) or 2 (6220) SATA Drive Bay(s) 1x GigaBit LAN 3x USB 2.0 HiSpeed 1x eSATA 2.0 (3Gbit) (only 6210)
The icy-box has a outdated u-boot as bootloader. You need to flash an up to date version. (IPFire image ship a working image in /usr/share/u-boot)
After flashing you need to add a basic config environment:
boot_dev=ide boot_part=0:1 bootcmd=${boot_dev} reset; fatload ${boot_dev} ${boot_part} 0x8000000 boot.scr; source 0x8000000; bootdelay=3 console=console=ttyS0,115200 earlyprintk fdt_addr_r=0x6300000 fdtfile=kirkwood-ib62x0.dtb kernel_addr_r=0x6400000 ramdisk_addr_r=0x6900000 root_dev=/dev/sda3 soc=kirkwood
