maybe there are other solutions, but AFAIR the DBX version in Delphi 7
can't support Firebird 2.5 for many reason.
I know that Delphi2010 has correct DBX driver for Firebird, that is
independent from the Interbase one but isn't supported by Delphi 7 (it's
DBX 4.0 AFAIR).
So the path is
- upgrade to Delphi XE
- pick a driver from third party source (there are quite a few).
HTH.
