looking forward to use this too but I am missing something... the walkthrough by jimes does not tell us which CHDK zip file to download and unzip onto the card and the download page and autobuild pages don't list the SD790IS....   there has to be more than DISKBOOT.BIN....

the zip file has a bunch of empty directories, a data folder with badpixel.cfg and two files badpixel.bin and CCHDK.CFG  and does not load (bootable SD card, write locked, with DISCBOOT.BIN)

You have to unzip the whole archive to the card, so that the CHDK directory is a direct subdir of the rootdir.
DISKBOOT.BIN must be placed in the rootdir of the card.

Then you have to load CHDK via the firmware update function: Start the camera in play mode and go to the
options menu and go to firmware update.

Hey everyone I'm currently having problem converting the .crw files into raw files. I tried changing raw file prefix and extension but no luck on that. So if anyone can help me out with this problem I would appreciate it.

Read a bit in the sticky threads at RAW Shooting and Processing, especially CHDK & RAW - a never ending story (Beginners read here please)...
-->Enable DNG support to shoot directly in DNG format (Forum link: Enable DNG support guidance).

To work with CHDK RAW files you need a software which supports them, e.g. DCRAW since version 8.94.
So you can convert the CRW's to the PPM format with DCRAW, most apps like PS, XNView etc. supports the PPM format.
If you're working with MS Windows or a Mac, you'll find compiled binaries here: Pukkita's Digital Darkroom Corner: Downloads

I just bought the 790 at Costco. It has firmware version 1.00E. Will this port of chk work on that firmware?
I have a new 2 gb sd card that came with the camera, I have copied the files to it. It has the chk directory and on the root the diskboot.bin.
When trying to use the cardtrick 1.44 it will not format my card, but the card works in the camera. I am not sure how to make it bootable without using the cardtrick utility. I do not see an option in the menu to update my firmware. I tried using the PS.F12 file also. No luck.
I used chdk on my S3 camera a couple of years ago and did not have any problems.
Can anyone help, I really enjoyed using the program on the S3

PS.FI2 is only manual boot, DISKBOOT.BIN is auto.
Be sure that the PS.FI2 file is in the root directory of your card, PS.FI2 in case you need it.  Start the camera up in review mode, press the menu button, and at the bottom of the list it should say "FIRM UPDATE", press ok and you should have CHDK.  If you want to make it bootable, (be sure you have the previous steps completed) place DISKBOOT.BIN in the root directory.  Now start up CHDK with the PS.FI2 method, put the camera into ALT mode (press the print button until "ALT" is displayed at the bottom) Press Menu go to Misc. stuff, select make card bootable, lock the card and your good
