I can vaguely recall my system giving ramlib errors with Amidock.
MCP ramlibpatch used to be included with MCP, but with the latest releases it's not included anymore.
You can find it in the RTGMaster archive on aminet though.
A similiar module is included in the blizkick archive, and the romfixes module of blizkick also includes this patch.
Anyway, it can't hurt to give it a try when your system is
giving you this error.
