Nice that someone uses DESI-III with FreeDOS :-)

Very strange ...

1. Try EDR-DOS
2. Reveal what EMM386 you are using (regrettably DESI-III requires EMS IIRC)
3. Other stuff (driver, TSR) present ???
4. Free more low memory (frustrating low memory wars ... I hate them)
or EMS page frame size

This is most like related to the low memory hogginess of DESI-III and
the EMS usage :-(

Of source, porting DESI-III to 32-bit DOS (WATCOM FORTRAN) would be a great
thing :-)

IIRC you can't even exit DESI-III with the keyboard (this is a BUG ...)

~~~ wow ~~~
