How to make big, more than 4GB SD Cards bootable for CHDK or Magic Lantern (windows):
- get this app:
http://pel.hu/down/bootCF.exe- get this dll:
http://www.4shared.com/get/iUI1iIlG/cc3280mt.html- put them both in a folder on your drive
- open command prompt (cmd), change to the above folder
- usage: bootcf.exe <drive:>
- when prompted "(W)rite labels", press W key, then press Enter key
- to check, run again bootcf.exe <drive:>
- you should see: "Labels found at 0x47: EOS_DEVELOP, 0x5c: BOOTDISK (R)emove labels"
- just pres Ctrl+C to exit
After this, follow instructions to install CHDK / Magic Lantern on your card.
The application similarly allows to remove the bootable flag from the card, by pressing the R key when prompted.
I tested with a Transcend 4GB card, and a SanDisk Extreme II 16GB card, both run fine!
