TN4063C.txt   TD386 and DOS 5.0 Compatibility
Category   :Pascal
Platform    :All
Product    :TD  2.01

Description:

TD386 ( & TF386 ) will hang on startup if you use DOS 5.0, and 
have the command:
DOS=HIGH
in the CONFIG.SYS file.
 
This does not happen if DOS is not loaded HIGH.
The machine is hanging inside of the DOS program loader code.
When doing the equivalent to DOS=HIGH with DR-DOS 5.0, this problem 
does not occur.
All of the "new" commands to load device drivers & TSR's high in DOS
5.0 are incompatible with TD386, as they use V8086 mode ( ala QEMM &
386MAX). Note that loading device drivers & TSR's high is different
from DOS=HIGH , which loads the DOS kernel into the XMS high memory
area, and which does not use V8086 mode.
