No worries. I am relatively new to CHDK testing, although I have been using it on my SD900 for a number of years. I got my firmware version using the vers.req and FUNC SET + DISP combo. Yes, that is exactly what I mean by firmware display. There are three lines of text starting with 'CHDK Firmware'. There is no graphic logo. The camera loads in review mode. It turns off when I attempt to switch to shoot mode. With that being said, the <ALT> symbol displays when I press the print button, not DISP. I get the CHDK menus when I press MENU, and I get the Script menu when I press FUNC SET. Hope this helps.
