Have you also read
this ?
(Mac's frequently refuse to make downloaded files executable)
Also, to get a 2 partition card to boot:
1) don't forget to
format both partitions after creation
1.5) the small FAT16 partition must be 'bootable-for-CHDK' which means it has to have
the string BOOTDISK written to sector 0 at offset 64 decimal / 0x40 hex
2) only DISBOOT.BIN should be on the small FAT16 partition, all others (CHDK folder !) on the large FAT32
3) the small partition should be active, and the card locked; CHDK should then boot on camera start,
and should automatically 'see' the large partition and use it to store pics
HTH,
wim
