Topic: FW loading.

I have a terminal connected to my BB Chumby 3.5" internally.
The original FW got lost in the hackinh.
I run rom.falconwing.img
works good EXCEPT....
The usb port and the wireless are not enabled in this FW
I dont have a network.conf file.
Is there a way to load the TGZ files onto the internal sd card so a FW update happens ?
Would you put it in /mnt/storage directory ?
I have a win7 computer to r/w the sd card with an adapter.
