I have down loaded all versions of CHDK for my Canon S100
I have 3 cameras
One card works and two do not
They were installed when I bought it
I downloaded ACID and Camera version 1.3
Both say I have a 101B firmware
I used the disk boot tool and moved CHDK plus diskboot over to the SD card that was fully formated and formatted in my Camera
Nothing stops the bootup saying Memory card locked
I am ready to kill myself with a dinner fork if I cant get this to work
