Debian on NSA221 (4 replies)

OK, I've dug all over the forum as well as the internet and can't find any info on whether anyone has ever tried to get Debian or anything else running on the older Zyzel NSA221. Is this doable? I've successfully done this on Buffalo NAS's, my Zyxel NSA310 and NSA320 units but I can't see any info on the NSA221, hence the question.

Looks pretty close to the NSA320 device. Can this be done or is the CPU too different from anything else to be workable?

Here's what I can tell you about it.
