  Forgot to add some additional info about DOS 4. Several UNDOCUMENTED DOS
calls have had some changes. The most annoying is function 1Fh, Get default
DOS parameter block and 32h, Get DOS Parameter Block. Apparantly, the
number of sectors for FAT entry is now a WORD instead of a BYTE. This has
pushed the directory sector #, Device header address, Media descritor (!!),
and other info up 1 byte. If you have a program that tells you that your
media descriptor is 0, then it is using one of these functions.
  Also, Function 52h, Get Disk List, has also changed. Most especially, the
data pointed to at offset 16h has changed, and is larger.
