Ok, I really appreciate your development, but just to make it clear:

I have a Canon 350D with firmware 1.0.3 (as suggested) and an 8GB CF card. To make it bootable, and in a safe way, is it enough just with using the Card Tricks V 1.45?? I read somewhere i need a partition, but im not sure if that is what Card tricks actually does.
I just want my 350D with the CHDK tweaks. Particularly Timelapse.

Just to clarify: My CF card is currently formated by the camera.

Update: I did it that way. I got an spooky "err 99" after i used it for a while the 1st time, but now it works ok.

Any clue on the "99 err"?

I just bought 400d chosen mainly because of this hack.

But I can't make it work. Followed the instructions from here but when I put the CF in the slot in the final step, the blue button doesn't light. Instead, the camera turns on, but the display is not working. I can focus but not take pictures. Also, cannot turn off the Camera.

Win 7 x64, CF 4GB (3.8GB)

What am I doing wrong?

Cameras released in 2011 allow CHDK to autoboot on a FAT32 card. I'd like to modify my OSX SDMInst app so that it can do create such cards - currently Mac OSX users who want to create bootable single partition cards > 4GB (e.g. for an A3300) are out of luck.

My question is this - where does the 'BOOTDISK' string have to be written on a FAT32 card? Is it still at x'40'?

Hi,
I searched for this, but found nothing.  Cardtricks (145) is intolerably slow when formatting a 4gb card on my Windows 7 laptop.  I need to use the windows format tool which is very fast and can do fat.

EOScard 1.1 writes the "BOOTABLE" string to 0x5C for a FAT32 card.  Anyway to change this to 0x1E0?

Yes. Use EOScard 1.2

OK, I've tried everything here, but I just can't seem to make my 64GB exFAT card bootable -- and boot CHDK on my SX230HS camera.  I've tried everything, but I still get no CHDK (camera just says card is write protected) when I boot from my 64GB exFAT card.

Can anyone help me get my SX230HS camera to boot CHDK from my 64GB exFAT card?

Notes:
  • Camera is SX230HS, firmware 1.01A
  • Card is "Komputer Bay" 64GB SDXC card, formatted as exFAT
  • Booting CHDK works great with another card of mine - an old 16 FAT32 card
  • Running CHDK works great using the "firmware update" method - with all my cards
  • I've tried making my 64GB exFAT card bootable using CHDK's "Make Card Bootable" menu
  • I've tried making my 64GB exFAT card bootable using EOScard.exe version 1.2
Thanks for any advice!

AFAIK P&S cameras do not boot from exFAT. Only FAT16 (all cameras) and FAT32 (DRYOS R47 and later cameras, which is everything released from 2011 on)

Don't forget what the H stands for.

Thanks.  Sad, but good to know.

No, I didn't notice!  Got here via Search.  I'll keep that in mind, and ask elsewhere.
