Patching then fixing the CRC is easy with dEd, but inserting bytes to make room may be trickier. I have not done that.

I have, however, renamed using ezgen from Burke & Burke. That would be normally used on a bootfile, since you can “link” to individual modules inside of it, and insert or delete or … rename.

I suspect you could “ezgen -dm module” on disk and then “l module” to go to it and then “r new” to change the name, then exit and it would update the CRC.

I would do stuff like…

ezgen -dm /h0/os9boot
l h0
r harddrive1

…etc…

Others here may have other utilities that are easier. There’s another that is included with NitrOS9 I think but I have never used it (works like ezgen so probably can rename as well).
