Hello.  This is my first time to post to this board.  I doubt it will be
the last!  I have a question about the DOS 4.01 use of memory(RAM).
I have 1024K of memory on my  XT mother board, but DOS refuses to recognize
it.  I realize that anything above 640K is expanded memory.  My question
is this:  

    What do I have to do to get DOS to recognize the other 384K?
    and, What will it be used for?

I've been reading the User's Guide and Reference Guide and the book says
that I need an EMS controller.  Is this right?  I mean, the memory is
on-board and the BIOS ROM seems to recognize it on boot-up.  Why would
it need a controller for something on-board?  I've tried to install the
SMARTDRV.SYS but get the error "No Expanded Memory Manager."  Is this
another piece of hardware or software?

Just for backgound, incase it's needed, I have:

Flytek ST-12 mother board with
   -V20 microprocessor
   -8K on board XT BIOS
   -switchable from 4.77 MHz to 12 MHz

You may send your replies to me through e-mail or post here as I have 
become an avid reader of this group.  Mail responses will be summarized
and posted to this group.
