Hola amigos, la solucion en modifican el archivo "dbxdrivers.ini". Puede encontrar este archivo en la carpeta: \Common Files\Borland Shared\DBExpress [archivos de programa] o C:\Documents and Settings\All Users\Shared Documents\RAD Studio\dbExpress dependiendo de la versión de Delphi.

y agregar lo siguiente dependiente de la verion delphi:

Para todas las versiones de Delphi/BDS/RAD Studio:
[Installed Drivers]
InterXpress for Firebird=1

Para D6, D7:
