I have read through the FAQ and a few other articles online that show how to determine the firmware version of your camera. I have done the following:
1) Created a file called ver.req and made sure it was not a text file
2) Copied it to the root directory on my SD card
3) Put the SD card in my camera
4) Turned it on in review mode (play mode) and held the FUNC. SET, then pressed and held the DISP. buttons.
All I got was some rotating boxes showing the current time.
I read a forum post that said you could get additional information by naming the file vers.req so I tried that as well. So far, I have had no luck determining the version of my firmware. I would greatly appreciate some pointers as CHDK looks like it would be an awesome way for me to get RAW support without purchasing a whole new camera.
Thanks for your help :-)
