Xavier,
Great thanks for all that.
Now I have no problem getting access to the SD card. This is the method I used. Could you tell me if this is the best way, or is there maybe something from the main FM3 menu? Either is fine of course, I just want to be sure I'm doing the right thing:
<<Power the FM3 off
Power it on while holding down the red menu button
You will get a menu. For SD card access it will say to push button 3. Do this.
Wait up to 15 seconds and you will see the image appear on the computer screen.
Again, at your own risk -- and whatever you do don't accidentally push button 1 when you're in the boot loader, LOL>>>
