Using CHDK

To Start – Auto load method

Cameras that have an SD card that has been prepared as

bootable and is locked (write protected,

with the slide tab on the side of the card), will load CHDK automatically when turned on. This

is usually called the “Autoload” or “Autoboot” method, using a camera version specific file

“DISKBOOT.BIN”

The card lock is bypassed by CHDK and photos and video are able to be saved as normal.

– Manual load method

When the SD card has a camera specific file, which for some versions is “PS.FIR”, and others

“PS.FI2”, the card is left unlocked and then:

1. Switch the camera on in Play mode, not Record mode,
2. Press the

MENU

button, then press UP once (or scroll down the menu list)

3. An option to update the firmware appears, Select that option (press

FUNC.SET

)

4. Confirm the update, (

OK

-press

FUNC.SET

)

See:

for instructions to make memory card bootable, and information on the loading process.

The CHDK splash screen will appear for about 2 seconds, while the Print button blue led flashes,
confirming that CHDK has now loaded into the camera’s memory. (The splash screen can be disabled
in

Main Menu > Miscellaneous stuff

).

CHDK will now be running in the background. Some features are enabled by default, for example,
battery and

file space indicators

. However, most features are disabled by default.

To make changes to how CHDK operates, you start by entering

mode.
