[comp.sys.ibm.pc.misc] Expanded Memory Problem

smlg1015@uxa.cso.uiuc.edu (10/22/90)

I am trying to get extended memory to be emulated as expanded memory
on a Northgate 386 system.  I add a 
line in the config.sys file:

		device=c:\dos\emm386.sys 256

which (1.) Makes 256K of the extended memory look like expanded memory
      (2.) Steals 384K from system memory
      (3.) Starts making characters disappear from the screen


I don't understand why (2.) would occur.  (3.)  probably occurs
because the emm386 driver and the VGA driver  are overlapping in
memory, but I don't know how to correct the problem.


Can somebody explain  what's going on?   I'm sure that (3.) has
a simple solution.


Thanks,

This isn't the way to do it.  Get QEMM 5.0, you'll save yourself a lot of
headaches.  Or download EMS40.SYS from one of the archive servers.  EMM386
doesn't do real expanded memory emulation.
