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The icy-box has a outdated u-boot as bootloader.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

kernel_addr_r=0x6400000
ramdisk_addr_r=0x6900000
