The Canon PowerShot A570 IS is a 7 MP digital camera with image stabilization, launched in February of 2007.

CHDK is available for the A570is with firmware version 1.00E and 1.01A from the Download page

Firmware information is given if ver.req exists on the SD.

Power on in PLAY mode with ver.req file on SD card, press and hold FUNCSET, press DISP reveals the firmware version.

...subsequent press of DISP (while still holding FUNCSET) reveals the next fw information pages (2x).

Since CHDK changeset #911 the <Alt> button can be set to PRINT (default) or DISPLAY from the "Miscellaneous stuff" / "<ALT> mode button" CHDK menu
- If DISPLAY is selected for <Alt> button: press DISPLAY quickly it will act as your <ALT> mode button, but if you hold it down for a second, it acts like the DISPLAY button normally does
