Thanks for help

Maybe someone will need it: step-by-step for all of you how don't know how to start CHDK with diskboot.bin. I'm not involved in any porting job and information provided here were previously posted mainly by
fboesch,
pev69 and others. They done hardest job here. So only gathered informations:
1. go to
http://stereo.jpn.org/eng/sdm/index.htm and download package with sdminste.exe (e.g. Common_Files.zip)
2. unpack and run sdminste.exe
3. select drive where SD card is
4. press "make bootable disk"
5. copy CHDK folder and diskboot.bin to SD card
6. write protect you card and place in camera
7a.) to start camera in play mode press PLAY button or other method press ON/OFF button for short time (less then 1 second)
7b.) to start camera in rec mode press ON/OFF button for longer then 1 second
8. If CHDK starts properly splash screen should appear and auto focus assist LED (green in front of camera) should blink twice
If I'm right this apply for cards
smaller then 4GB. For bigger (SDHC) cards look here:
