Installed 10g on W2K3 concurrently with 9i - cannot connect to 10g

Question

On a Windows 2003 server running Oracle 9i, I installed the Oracle 10g database. After the installation, I'm unable to connect to 10g database but can connect fine to the 9i instance. .
At the SQL prompt, while trying to log as system/manager@STR05CI I get the following errors:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
If I connect as sysdba to start the database, I encounter the following errors:
SQL>Connected to an idle instance
SQL>startup
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00132: syntax error or unresolved network name 'LISTENER_STR05CI'
Some of the things done:
-Two ORACLE_HOMES installed
-Two different ORACLE_SID (one for 9i -D5BSM - and one for 10g - STR05CI)
-Shutdown the listener for 9i and running only the listener for 10g
-modified slqnet. ora with SQLNET.AUTHENTICATION_SERVICES= (NONE)
-All ports on 1521
Pasted below is the status of the listener:

The command completed successfully
Besides the things listed above, I've been unable to locate other instructions on how to install two different database versions on the same server.
Also, how do I resolve the 'status UNKNOWN' for the STR05CI instance so that it becomes READY?
Any help would be appreciated.
Thanks!

You have an entry LOCAL_LISTENER in your spfile, that's not necessary (at least for single - non RAC - instances) as long as listener is running on port 1521. If you specify this parameter, you have to add address resolution to tnsnames.ora .
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Basically that means database is not started, it also happens when tnsnames.ora entry points to an non-existing SID.
'UNKNOWN' means there's a static entry for the instance in listener.ora, 'READY' is shown when there was a dynamic registration of the instance with the database. PMON background process does this automatically, when there's no entry in listener.ora and listener runs on port 1521.
