Tandy 4020SX vs. EMM386.EXE Solution

        There is a conflict with the Tandy 4020SX that uses a nonstandard
drive like the 105 MB (it came with the unit that we purchased) and the
EMM386.EXE memory manager that comes with MS-DOS 5.0 or 6.0. The conflict
is most evident if one uses the NDD program from Norton (Disk Doctor). NDD
reports bad boot sector and/or bad fats. If one removes the EMM386 line 
in config.sys, the apparent problem goes away. Other disk utilities like
defragmenters are probably also affected.

        The conflict can be removed by adding the parameter NOMOVEXBDA on
the DEVICE=EMM386.EXE line to prevent EMM from moving the Extended Bios
Tables. This solution was given to us by the Tandy tech line in Texas.
This parameter is documented in DOS 6.0 and also works in DOS 5.0
although not documented in that release.
