Hi. I would like to understand better what I am doing here with respect to extended ROMS, etc. First of all, where does the extended ROM live in the file structure -- I would like to see what is in it even before the update? Also, how do you lock or unlock the extended ROM? Is there any documentation as to what goes where on these devices -- ROM VS. extended ROM vs installed software?
I find this process really interesting and I thank in advance all the folks who looked at these things with hex editors, ec.
Have fun.
