Does "DEADF00D" mean anything to anyone?

Looking at TIVOPROM.BIN in an editor shows the text "DEADF00D" (with two zeros in the food) near some password changing text.

Anyone know what this is? Maybe a secret password?

8 hex characters commonly used as a network name when Novell was bigger than Microsoft.

It looks like TiVo's version of DEADBEEF with a minor substitution.

What's next, CABB1E ED?

It is indeed analogous to DEADBEEF. If there's anyone out there whos ever worked on Stratus FTX, you might be used to seeing BAADF00D instead..

DEADF00D and DEADBEEF are "words" you use to fill segments of memory. The idea is to help you identify memory leaks/pointer arithmetic errors. If you're program's crashing, you step into it. If you suddenly start seing "DEADBEEF" or "BADF00D" where your strings should be, you know you've got a pointer problem.

Actually, TiVo uses both deadbeef and deadf00d all over the place. From what I can tell, deadbeef is used when there is a location (Usually in a file or on a partition) that has no assigned meaning, and is used to pad to a certain size, usually the next sector boundry. Deadf00d is used when the that location has an assigned meaning, but no assigned value.

And then there's Java, which uses CAFEBABE quite a bit internally, at least in Sun's implementation.
