Lan-wei,

the file mapinfo.prj under your MapInfo installation directory contains
all of the geodetic parameters used for ellipsoids and projections in
MapInfo. It can be viewed with any text editor.

Read the appendix on projections in the MapInfo manual to get an
explanation of the elliposoidal and projection parameters used.
