Re: [cobalt-users] StaQWare [RaQ 3]

[Sai Sivanesan <sai@xxxxxxxxxxxxxx>]

We use staqware on 2 raq4i's

On the box it says - it will work w/ raq3i or 4i  "dual ethernet interfaces.
and identical hard disk capacity."

 don't see why you cany install an intel pro 10/100 pci card and get your
dual adapters..... 

Answering one of my own previous question as well, according to Sutherland
Consulting (Cobalt tech support) the staqware does an exact mirror of the
hard disk, so in regards to your question about hacking - yes you get double
hacked so to speak.
