Programs that use the DOS 1.x style FCB file services can't handle disks
with more than 64K of sectors, unless SHARE is loaded.  Part of the reserved
section of a file control block contains a single word giving the disk
sector of the directory entry.  I don't know what will happen if you
try to run one of these ancient programs on a huge disk with too many sectors,
but wouldn't really want to try.

This information is contained in Ralf Brown's interrupt list, available
somewhere near you.
