Hello, welcome smore !
I just got this camera....1.01A...
soooo what do I do?
Your camera & fw version is supported by CHDK,
now you should read a little in the
CHDK wikia, e.g. start with the FAQ, then go on with "CHDK for dummies"...
After that:
-Download the CHDK for your SD1100 fw 1.01A from the autobuild server (wikia, "Downloads"; use the "complete" package).
-Use Cardtricks to format your SD card (max. 4 GB), make the card bootable, unzip the downloaded CHDK complete package to the card.
-To start your camera with CHDK LOCK the card...
(you'll find all needed links in the wikia)
