old canon s230 question

does anyone know what the largest size CF card is that can be used in the canon s230?
I looked over the user's guide, but all I could find was that you can hold xxx images on a 256mb card.

thanks,

It is probably using FAT16, so the limit is probably 2GB.

The file size for FAT16 is 2GB. The maximum partition size is 4GB.
