[comp.sys.ibm.pc] Using Himem for TSRs on 386 ?

markad@blake.u.washington.edu (Mark Donnell) (06/28/90)

I have heard talk on the net about being able to relocate 
TSRs to the memory between 640 and 1Meg on 386s. As I have
previously understood, this required the TSR to support
such action. Is it different for 386's? In my hacking and playing
i have not run across a way to do it, but if it is possible, it
would be very useful.

On another track, does anyone know if Windows 3.0 is able to
run 2 (or more) dos shells concurrently on a system with only 2 Meg
of memory? When I tried it on a demo machine, it required whichever 
of the two was active to be exclusive - no background processes.
I would be interested in it if it could pull this off.

And, does anyone have a list of progs which have problems with AMI?
I am working on my vendor to replace it, and he wanted some reasons
to send back to the manufacturer.

Thanks ahead of time.
Mark

There sure is, Mark.  Pick up a copy of QEMM 5.x, it includes a loader
program to move stuff from conventional to high memory (between 640K and 1
MB) at boot time.  I'm not sure if 386-to-the-MAX has this or not (I hope
so).  Most TSRs don't mind being moved, as long as there's enough contiguous
high memory so the TSR can load (often times TSRs take a larger chunk to
load than the piece that stays resident).
