IBConsole does not work anymore in the same way as it did, but you can
connect to Firebird 1.5 as a "false remote" server. Register a new
database and in the dialog wndow set this this:
- check the "Remote Server" radio button;
- type localhost in "Server name";
- choose "TCP/IP" in the "Network protocol" combo box.
Hope this helps.
