Hu? Well MS-DOS 6 SHARE.EXE did hook there and at Int2F only. And are you sure they hook Int20 but not Int27? Sounds strange.

Yes because you should use the pointer at 0:C1 instead of the SHARE.EXE hooks

These pointers were meant to be hooked by SHARE.EXE, and I'm certain were only called by DOS, not changed.
