I have replaced my batteries without erasing the firware several times. The
trick is replacing the batteries one at a time with the brick turned off.
You have then several (10 or so) seconds between each replace. If you leave
the brick switched on it drains a lot more power and it can hold the
firmware only for a couple of seconds without a battery before it wipes the
firmware.
But since you can download the firmware at 4x speed, it doesn't matter vey
much, does it? ;)

| Probably related to the garbage on the lcd that you get when turning off the RCX with a sensor active: if there is a light or rotation sensor or a pressed touch sensor connected to the RCX when you download firmware legOS will crash immediately (...)
