Autoload fails on S2 IS

First, let me say that CHDK is awesome!!  And I'm serious, I'm not just sucking up to get help with my problem.

Autoload doesn't seem to work for me.  I have an S2 IS (1.00e) and loaded CHDK 148 on it.  Used "make card bootable" then locked the card.  When I turn on the camera, it just reports a "card locked" error and won't take pictures.  The card is 1GB which I assume formats to FAT16 by default.  I reformatted it with "format I: /fs:fat" just to make sure it was FAT16 and that didn't fix the problem.

Interestingly, the file browser in CHDK sees the DISKBOOT.BIN file, but reports ??? for the file size and no timestamp.  The file looks fine when I view the card with a card reader.

Any ideas?

Update: The problem only occurs with my A-Data SD card.  Both of my SanDisk cards autoload fine.

It's normal. Because OS treats this file as a special device.

Yeah, that card has always been flakey.  I wish I had enough info about the exact model so I could add to the SD Benchmarks page.  All I know is that it is an A-Data 1GB card (and could very well be counterfeit).

Thanks!

Format the card using the camera menu. Then copy the files using the uploader or card reader, making sure you unmount the device so that the buffer gets flushed.
I don't know what sequence I'm using to make the card bootable, but try setting it to read-only BEFORE making it bootable, might work.
