When ASE is booted with traceflag 3607 on (using -T3607 as a parameter in the RUN_SERVER file), recovery is not run on any database including master. 

This is useful in cases where recovery of master hits a fatal error, preventing any further recovery of the server.  The traceflag allows access to the system tables, allowing the contents to be extracted for use in rebuilding the server.

When booted using this traceflag, the errorlog will contain something like this in place of the usual database by database recovery output:
