You set the ColumnAttribute for BOOLEAN in the dataset and provide
the True and False values.

In code you would do:

MyDataset.ColumnAttributes.Add('MyField=BOOLEAN=T,F');
(substituting whatever values your DB expects for true and false).

You can also do it at design-time in the ColumnAttributes property,
one line in the stringlist, MyField=BOOLEAN=T,F or you can do it in
the Fields Editor on the ColumnAttributes tab.

You can alternatively do it on your IB_Connection's ColumnAttributes
property, e.g. MyDataset.MyField=BOOLEAN=T,F

If you are using a domain (e.g. D_Boolean) for your Boolean, you can
include fetDomainName in the FieldEntryTypes set. In that case, the
ColumnAttributes entry on the IB_Connection would be
D_Boolean=BOOLEAN=T,F

and then all fields in all tables using that domain will behave
properly as Booleans and store the correct values.
