Installing the CHDK
3. The distribution contains a file
ver.req
or
vers.req
. This allows you to
determine the real firmware version as described in section 3.2. If it
does not match your guess, download the correct version and unpack it
into your card.
4. Now you are ready to boot manually. Leave the camera in
Playback
Mode
and insert the card. Press
MENU
and navigate down to the last
item (
Firm update…
). Press
FUNC/SET
, select the
OK
button, and confirm
again with
FUNC/SET
. The CHDK is loaded and will soon show the
CHDK splash screen. It stays loaded until the camera is switched off.
Actually, no firmware upgrade was performed! The
Firm update…
func-
tion was just hitchhiked by the CHDK.
5. To enable the AUTORUN function, you must make your card bootable.
That can be done with the CHDK, too. Press the
ALT
key (
chapter 4
) fol-
lowed by the
MENU
key to invoke the CHDK menu. Navigate to
Miscel-
laneous stuff
>
Make Card Bootable…
and press
FUNC/SET
.
6. Switch the camera off, remove the card, and lock the card to enable
AUTORUN mode. Insert the card again and switch the camera on. CHDK
will now boot automatically each time the camera is switched on—
until you disengage the write protection lock.
Once you have installed the CHDK on your card, you should, as a matter of
fact, avoid formatting your card to get rid of images. Formatting would also
delete the CHDK and require a complete reinstallation. Instead, you have two
options for deleting obsolete pictures:
f
Use the camera’s original delete functions to delete images. Switch the
camera to
Playback Mode,
press
MENU,
and select
Erase…
Then you can
delete by selection, by folder, or all images. There is a hitch: the camera will
only show JPEG images or folders containing JPEG images. RAW and DNG
images obtained through the CHDK (section 4.5) are not shown and not
deleted.
f
Use the file browser provided by the CHDK (section 4.10.1). Press
ALT
(
chapter 4
) followed by
MENU
. Then select
Miscellaneous Stuff
>
File
Browser
and navigate to the folder that you want to delete. Press
DISP
and
answer the prompt with
Yes
.

The warranty question
The big question for many camera owners is: what about the manufac-
turer’s warranty when I install the CHDK in the camera? We don’t think
that there should be a problem. The CHDK is installed on the memory card.

The

function of the
camera can be used to load and
activate the CHDK.

The entry

does exactly what it says.
