Retrieve linked servers out of system database files? I have the data and log files of a SQL-Server that has crashed. It's user databases have been restored. I am looking for the jobs and linked servers that have been there before the crash. I attached the old system databases and looked ad some views. Jobs have been found quickly in msdb. 
but sys.servers and sys.sysservers seem to query and display the current server always. 

I tried:

select * from sys.servers 
select * from msdb_old.sys.servers 
select * from master_old.sys.servers 


but all of them return the same, only the current server config. 

Are the linked server objects persisted and queryable anywhere in the old files?
The answer placed here for future reference if needed. It looks as though this data may be in a hidden table in the master database sys schema named sysxsrvs.

According to what I could find this may be available to be queried if connected through the DAC.

It also uses sysobjvalues (contained in all databases). I believe to populate the srvproduct/providername fields.
