ran CT and got FAT on card
Make bootable not highlighted
I suppose 'not highlighted' means greyed out / not clickable ?
CardTricks will 'grey out' the 'Make bootable' button for 2 reasons:
1) the card is
already bootable, in that case 'CHDK Autorun' should say: ON ('BOOTDISK' at 0x40)
2) the card is formatted as FAT32 (check what it says after 'File System') - if it is, use 'Format as FAT'
and the button should become available
hope that helps,
