Just a note to anyone planning on following in my footsteps.

1. You will need an old XP machine with firewire.
2. You can find a WIA 5.5.0 driver on Canon's USA site (the European WIA 5.5.0 driver doesn't appear to work). You will need this to make the firewire port work.
3. Then you can find EOS Viewer on Canon's Europe site. This is the utility that will let you change your copyright information and custom functions. While you can transfer files with USB 1.1 (*sort of), you will need firewire to change settings.

*sort of - USB1.1 transfer is at a rate of about 1 image per minute. I started a transfer, made supper, let the dogs out, went to the store, bought a CF reader, came home, and my USB transfer still had an hour to go, so I canceled it, and transferred the images via USB 2 Lexar multi-reader in about 3 minutes.
