That version of SHARE just uses the SEGMENT of the List of Lists, to find the kernel, and then overwrites hardcoded offsets in the kernel (not looking at the CONTENT of the List of Lists at all) with a bunch of hardcoded bytes. That is bound to fail on any kernel except the MS DOS 6.22 one for which it was designed. It might even fail on a MS DOS 6.22 for another language, for example German, than the one for which that SHARE was designed. I think it would have no point to try to make FreeDOS behave "compatible" to that version of SHARE.
