"Upgrading" Intel InBusiness Storage Stations?

Michael Gilbert asks: "I have a 30Gb Intel InBusiness Storage Station, which is based on a limited version of FreeBSD 2.02 (see here) It is, as is usual, totally undocumented by Intel as to it's inner workings. Since both the 30Gb and the 60 Gb models use the same chassis, I was looking into adding my own 2nd 30Gb HD. Intel of course does not support such an upgrade. Does anyone out there have any relevant information as to the specifics of the unmarked jumpers and connectors on the unit's main board? Console port perhaps? Has someone already done this upgrade? While there may indeed be easier ways to add more networked storage to one's home network, the fact that Intel does not want me to do this only increases my curiosity and desire. Having discovered the (undocumented) telnet port, I can get a FreeBSD shell, and so far have surmised that due to the age/version of the FreeBSD system, the upgrade would require a new kernel, as this one seems to be static as far as not probing resources."
