Well., that's the story they're feeding me now. Something to do with the
fact that its a new range??????

Tell me about it.., Considering I had a bean on a CISCO 837, but Zen
told me outright that they'd not offer me *any* support if I wasn't
using a device purchased from them. This was the only non-usb rubbish I
could get from them..,
Sadly, I was beta testing the unit for SMC, and handed it back in :-)
Really pisses me off this.., I'm quite fond of the FreeBSDforums site,
one of the best *bsd-related forum site I've come across.., too.
Really appreciate your taking the time.

Stacey
