Questions about boot script !!!

Hello, I’m Total5200SDP user. I have some questions about boot script and
script files.

Few days ago I downloaded BSP 1.0.2 for Total5200. Then, I made new OS image
to upgrade my Total5200’s OS(v6.2.1 to v6.3) but there was no scriptfiles in
/etc/ directory.
On factory status, there was a script files like “boot.ksh, config.ksh,
netconfig.ksh etc.”
but on BSP, there is nothing else.
Also, there was utility named “netconfig” which is to set network parameters
easily. But there is not exist in BSP1.0.2.

Is this normal??? If anyone could answer this problem, Plz help me.
