Hi,
Since you mentioned CardTricks, I suppose you have seen
this thread ?
Does CardTricks detect "File System: FAT32" ? That would explain it:
CHDK (which is for Canon P&S only) can not boot from FAT32, so CardTricks will say:
"CHDK Autorun OFF"
Hacks for DSLR are not CHDK, and can boot from FAT32, so CardTricks will say:
"CF boot ON"
Hope that makes it a little clearer,
wim
