SYNTAX
EMM386 [on|off|auto] [w=on|off]

Enables or disables EMM386 expanded-memory support on a computer with
an 80386 or higher processor. Do not use this command when Windows is
running.

QUESTION:

Does one turn EMM386 by issueing this command at the C:\ prompt?

C:\EMM386 off

And would it be correct that one should never try to do this in a DOS
window?

Thanks
