master.mdf recovery

Is it possible to recover master database from problematic master.mdf and/or
problematic mastlog.ldf? No backups exist. The error that appeared in event
log is
Error:9003, Severity:20, State 1. and right after that: "Cannot recover
master database.Exiting" . The reason I am posting this is that I know there
is something starnge going on because there was no hard disk failure and the
problem appeared after power loss of the server. But scan disk did not report
any problem when the server rebooted after the power loss. So maybe the file
is "not so corrupted" or maybe it is a fixable problem. Thank you in advance.
Hi
9003: The LSN %S_LSN passed to log scan in database '%.*ls' is invalid.
You have corruption. SQL server might have been in the middle of writing to
the DB when the power outage occured. This can corrupt the DB.
Without a backup of Master, you are high and dry. Your only option is the
run the Rebuild Wizard (Rebuildm.exe), but you loose all your user logins.
Look up the topic in BOL.

|||From the console, you might be able to start sqlservr with the -T3607
option. The recovers non of the databases, system nor users. This may
allow you to export the configuration contexts from the system tables from
within the master database. If you do this, then there is a chance that you
would have all the information necessary to replace the content on a rebuilt
master. However, THIS IS A COMPLICATED SITUATION. CALL MS PSS FOR
ASSISTANCE.
