You may call it a PC, you may call it a low-cost Mac-Mini, Microsoft calls it an ULCPC – an ultra low cost PC, I call it an ideal home server. If your Linksys NSLU2 is great but lacks RAM and performance but you do not like the noise and power consumption of a standard PC, then read on.
The B202 does not support X64 (64bit mode), but as the hardware design limits memory to max 2GB, the no point in running a 64bit-OS.
Debian (lenny) boots without any problems, just WLAN is not recoginised.
