- CPU: AMD Geode x86 500MHz, 256MB RAM, 2x USB2.0, 3x LAN 100Mb, 1xMiniPCI
(from http://pcengines.ch/) - CardFlash 4GB (as root filesystem)
- WD Passport 500Mb (USB 2.0), using board's power via USB
- Power supply: DC 12V 20W :-D
I tried several x86 OSes on it:- OpenBSD 4.4: by far the easiest and +straightforward installation via PXE
- Debian stable: all Debian versatility thru your serial console installation :)
- Voyage Linux: 1-shot copy-to-CF (no PXE needed) && boot'it && apt-get'em =)
After some back&forth, I finally kept Voyage Linux, mostly because of
- debian versatility
- apt-get install screen ;)
- fully tuned for flash => root filesystem is booted readonly, with all the writable noise kept in memory by using aufs (union fs) and tmpfs
- smaaaaall (merely less than ~150Mb after install)
- openssl/OCF by default
- hardware watchdog, rng, aes support by default
- /proc/cpuinfo

- a full-steam-ahead rtorrent download at 1.5MBytes/sec makes it use ~25% CPU.
