CHDK wiki says that it is available for 1.03A:
CHDK is available for the SX10 with the following firmware versions: 1.00C, 1.01A, 1.01B, 1.02B, 1.03A
But when I go to download page: http://mighty-hoernsche.de/
there is a message saying that last autobuild failed and route me to an old version:
Errors occured during this build! Old version available here
And this one doesn't have the versino for 1.03A
I have also found a note here talking about 1.03A: http://chdk.setepontos.com/index.php/topic,2468.msg36383.html#msg36383
but, the file downloaded from there doesn't have some of the files that the other versions have, so, not sure how to install that one.
Can someone help me?
