I have an Ixus 310HS (firmware version 101a); I have DISKBOOT.BIN and PS.F12 on the SD card. I followed the instructions (on the ‘Prepare your SD card’ page, http://chdk.wikia.com/wiki/Bootable_SD_card
), see below, but step 6 didn’t start CHDK. What am I doing wrong?
UPDATE: tried again and got CHDK working but only if the card is in the unlocked position... When locked I can't access CHDK.
UPDATE 2: OK, I got to the end of the process, but this sentence needs to specify the method for turning the camera back on:
"Now each time that you turn your camera on, the CHDK logo should briefly display automatically, indicating that CHDK has successfully loaded". Given that the most recent instruction re turning the camera on was to use the Play button, the newbie now doesn't know whether that instruction still applies, or whether after completing this process that the On/Off button is used...
