I found a file that says it will allow me to use a valid H cam ID in my Tivo. It has the following instructions:

Just replace this with your old boot299.btl file in /etccombo and you'll be able to use H CAM IDs.

Can someone give me a step-by-step set of cmds that will get this accomplished? I have the Tivo drive in my computer... booted with Extreme2.5... hit enter twice so that I am at the Linux "/#" prompt....

Now what cmds do I type??
