There should be a warning that not all Powershot cameras are compatible with CHDK, like in the A90 family, there's only the 100 D and the 100 F versions available here:
Yes, of course, as you found out, people wanting to run CHDK alongside the stock Canon firmware (they co-exist peacefully) should have a look at the CHDK Wiki (
http://chdk.wikia.com/wiki/CHDK) and make note of which models and, within those models, which firmware is supported. Not all firmwares within a model series are supported, but new versions are added as the developers progress.
You can run a program called
ACID (Wiki:
http://chdk.wikia.com/wiki/ACID Software:
http://www.zenoshrdlu.com/acid/acid.html) on an image taken with the camera to determine the firmware version and subsequently ACID will download the appropriate software if available. Alternatively, you can take a blank, freshly formatted blank SD card (some cameras may want a single picture on the card...read the Wiki) with an empty file(s) named "
ver.req" and/or "
vers.req", load it into the camera, and press the appropriate buttons (dependent upon camera model) to read the firmware version.
All the info is in the Wiki, on YouTube, how-tos on
http://www.Instructables.com, or just Google CHDK. The amount of info available is a bit overwhelming but digestible in small doses.
