As far as I know the rom starts with "....gaonisoyP" and you can see it in my previous attachment.

Now I managed to blink the firmware out starting at 0xFFC00000. Download is available at http://www.megaupload.com/?d=6GANOZGT and is linked in the wiki article http://chdk.wikia.com/wiki/SD1200IS
In the attachment you will find the used programs. I wrote a new version of Load.exe in Java. The main advantage is, that I use CRC16 to verify the blinked bytes like in the sound-card version described in http://chdk.wikia.com/wiki/Porting_the_CHDK#Using_soundcard_input

No DirectPrint button, and no autoload with the card locked?

Hi all,
 I have an IXUS 95 IS, and using the ver.req file, I see version 1.00C.

I then unzip this package ( ixus95_sd1200-100c-1.0.0-1659-full_BETA.zip ) into my card, then I get to the "firm update" by powering on using the play button. Then when I hit OK to update from 1.0.0.0 to 1.1.0.0, I get a red CHDK logo for half a second, then it goes back to "no image".

And I think the firmware update failed, and there is no effect on the camera. If I repeat going to "firm update" I see the same offer to go from 1.0.0.0 to 1.1.0.0

I do not get anywhere from a locked card.

Do I have to make some changes to the CHDK files for this camera?

Please do not cross-post in this forum.  If we can help with your problem,  we will see the first post.   The extra ones just get annoying.  Thanks !
