SB5100 - config questions

Using Tom's JTAG Util, I have done this:

detect
ldram boot (select file "SIGMAX-BL_v2.6-LITE.bin")
ldram image0 (select "SB5100MoD.1.0.4.Beta.bin")
program boot
program image0

Power cycled the modem.

I have access to 192.168.100.1 (Motorola web server) and to 192.168.100.1:666 where I find the SB5100 MOD control panel.

Questions:
a) anything done o.k. so far, or did I miss something ?
b) Would a config file for SB5101E work on SB5100 ? If not, what can I do ?
c) if b=yes, what else do I need to get access to the network ?
e) For SB5101 I have a nonVol from a working unit - do I need the same for SB5100 ? If yes, where do I get it from ?

Greetings.
