Hack your Cannon

This Is getting all complicated and conviluded, not sure if it is worth all the effort if I have to do it again after I "power off". If I figure it out I'll give you an update.

If you read the doc here, you will fgind that you can lock your card and make it bootable (limited safely to 2GB or less cards).

Q. How can I make the CHDK program load automatically at startup?

A. You have to do the following actions:

• Copy the files PS.fir and DISKBOOT.bin into the root folder of your SD card (if you have not already done so).
• Load the CHDK program as described above.
• Enter <ALT> mode.
• Press Menu to enter the CHDK main menu.
• Go to "Debug Parameters" in the Menu on the screen.
• Select "Make Card Bootable". (It won't seem like anything happened. don't worry)
• Switch off the camera and take out the SD-card
• Lock your SD-card. This is mandatory. (But you will still be able to record pictures.)
• Reinsert the card back into the camera.

From now on, CHDK will load automatically on startup until you unlock the card again.
If the camera reports that the SD-card is locked, just ignore that information; the camera is still able to store pictures on the SD-card.
