Also I've read that the SD card does not need to be partitioned in a FAT 16 if it's over 8GB. Is this correct so far?
Not really. A FAT16 partition can only be a maximum of 4G large. On Canon cameras prior to 2011, the camera would only boot CHDK from a FAT16 partition. So you needed a small FAT16 partition for the boot and the rest of the card could be FAT32 (which can be much larger).
If so, what step am I missing to load CHDK? I have Version C firmware on the camera. I downloaded the latest and all it has is the diskboot.bin file. I know (at least pretty much think) that there should be more. What am I missing?
I've read this. This is why I posted. On that link it tells me that you have to make 2 partitons on your SD card when on this forum it said that you didn't have to and that CHDK will load fine. I'm just trying to filter out all the confusion. Partition in to 2 or not? Can I boot from an 8GB SD card?
I'm working away at rewriting that wiki page. For now, follow this :
1) The A2200 was released in 2011 and can therefore boot from a single partition SD card formattted with FAT32. This means you do not need two partitions to use an 8G card.
2) The easiest way to setup your card is to format it with the camera's built in format utility (which will get you FAT32). Unzip the CHDK distribution onto the card, including all the origina folders. Then load CHDK via the firmware update method using the PS.FI2 and go to the menu item that makes the card bootable. Select that, shutdown the camera, put the SD card lock into the LOCKED position, reboot the camera and CHDK should load.
Which works fine unless you don't have the PS.FI2 file - like with the early release of the A2200. In that case, unless you want to hexedit the SD card FAT, you pretty much have to set the card up with a single 4G partition (using SDMINST.EXE or cardtrick.exe) and pretend that you only have a 4G card.
link> CHDK Installation on cards > 4GNote that you will not be able to use dual partitions with the A2200 - that code was not implemented as it was felt it would not be needed once the camera went to full release status.
This will all get sorted out once the port gets to full release status and a ps.fi2 file becomes available.
