Hi Mates,
I want to AutoRun CHDK with my G9,

But i am sick of using the lock key,

No, the canon firmware doesn't load CHDK unless the card is locked, so no code change in CHDK will solve this.

However, many cheap card readers ignore the lock, or can be modified to do so. In that case, you never need to unlock the card.

Why is the canon firmware obliging this?

The card reader knows the card is locked using data it reads from the card or using a mechanical sensor?

Basically you are saying that the G9 does not try to read a firmware update from the card unless it is locked?

Don't know. Autoboot feature is for canon developers or service, I guess they don't care about locked card.

By mechanical sensor. The lock tab on the card is just a sliding piece of plastic, there are no electronics. So you can get a cheap card reader, open it up, and break of the little switch that touches the lock.

It won't read DISKBOOT.BIN, the autoboot file. Firmware update is a PS.FI2, but to use this you must go through the "firm update" menu every time you start the camera.
