Excellent research! Though you didn't take notes, you sure did hit quite a
few of the good binaries and interpreted quite a bit.
I'm just about done fiddling with the OS (since I'm getting antsy to implement
Linux) but I know there is a lot there they can do with it. I have to agree
that it certainly wasn't a 20 minute QNX install and a shove out the door.
Some very good thought went into this thing.
My $.02 for the day, that I haven't seen posted yet
I noticed that all the DSM data was stored on the sandisk in hd0t98 (proven
with a 'cat' of the device to see the data fly by).
What use is this? Try adding an entry and/or an attribute, then try deleting
it. While -X and -Y are options to dsmod, I get the error stating that
deleting items has not been implemented yet! :)
For those that like to screw around with the "nvram" using dsmod, I recommend
a backup (or two) of /dev/hd0t98 to a file on /app or /os.
