CHDK instructions
Download the correct firmware according to your camera model

Method 2 - Using CHDK itself to make the SD card bootable.
Start out with your SD Card Lock switch in the unlocked position (the small slide switch on the side of the card - see picture above - make sure it is in the unlocked position to start this process.)
Low level format the card in camera using the camera's built-in card format menu selection. Warning : any images on the card will be erased at this point.
Remove the card from your camera and put it into the SD card reader of your PC.
The card should now contain a single FAT32 partition. If you are using a large SD card, please make sure your camera did not format the card as exFAT - see warning note at start of this section. You may need to use something like FAT32 Format to reformat the card in your PC if so.
Now please check again (by looking at the properties of your card in an SD card reader in your PC) to ensure that your card is formatted either FAT16 or FAT 32 - and not exFAT!
Unpack the appropriate build of CHDK for your camera and firmware version directly to the card (including all subdirectories).
With the Card Lock switch still in the unlocked position put the card back into your camera.
Turn on your camera by pressing the Play button (or using the Play switch on some cameras). Do not start the camera with the On/Off switch or this process will not work.
Reset factory settings on the camera in order to enable the firmware update setting (if it's not there already)
Start CHDK manually by selecting the Firmware Update option in the Canon menus.
After the CHDK logo briefly displays, start CHDK by using the <ALT> key sequence for your camera.
Enter the CHDK menu (press play button and then MENU for the CHDK menu), and select Miscellaneous stuff -'> SD Card' -> Make Card Bootable
Turn your camera off, write protect the SD card by moving the little switch on the side of the card to the lockedposition, insert the card back into your camera. Note that CHDK will cause the camera to ignore the lock switch so that you can take pictures normally.
