Here are my thoughts (since you asked):

I've written some copy-protection software for a company that would not perform
correctly under DOS 4.0.

If I'm not mistaken, DOS 4.0 can have a > 32MB hard disk partition.  In order
to achieve this they had to increase the size of the directory entries
therefore breaking everyones software expecting only a 16 byte directory entry.

I don't know specifically what changes have been made (if any) to the FAT table
which could have significant and disastrous consequences if you attempt to do
anything worth while with those programs.

One day I'll have to go pick up a copy of 4.0. ??

By the way,  has Microsoft come out with an official copy of this yet or are
these all specific IBM releases still ?
