Subject: Using QEMM-386 v5.0 w/ Canon 386 - how it was resolved

This is an article letting anyone who cares know what I did regarding
my problem w/Quarterdeck's QEMM-386 v5.0.

I have a Canon 386 with a Tall Tree Systems' Jlaser Plus SA (a board
which lets me talk to an HP Laserjet II at 600x300 dpi).  I also have
a Logitech mouse and a Microtech scanner interface board.  I was using
QEMM to convert 3 MB of extended memory to expanded.  My problems were
a) when I tried to run the test program supplied by Tall Tree, my
machine would lock up, and b) when I moved the mouse in MS Windows/286
v2.11, again the machine would lock up.

I talked to a tech. person at Tall Tree who told me that they did know
that their software would run using Qualitas' 386 Max memory manager
and furthermore that they knew it would not work with QEMM.  I was
told that QD did not implement function calls 9 and 10 of the LIM 3.2
spec in QEMM.  QD however, told me that they did implement the LIM 3.2
and 4.0 specs and that Tall Tree was using function calls from a
previous spec which Qualitas' happened to support.  Athough I don't
know who is correct, 386 Max Professional did correct both problems.
(I got the Professional version so I could load device drivers into
High RAM).

There is a major difference and one or two minor differences between
the two products which I should note:

As I understand it, QEMM works w/DESQview 2.26 to provide
virtual-8086s for each open window.  386 Max cannot do this.  While it
would be nice if 386 Max could do this, I seem to be getting along
fine without this capability.  386 Max also does not have the
capability to load FILES and BUFFERS into high memory as QEMM does.
Also, the manual states that when running multitasking software such
as DV or MS Windows, it is important to reserve some space in High RAM
as a swapping region.  I did find that reserving a 48K swapping region
did allow my window size to increase to 512K.  However, under QEMM,
this was not neccessary and since I could load FILES and BUFFERS high
I was able to get a window size of 560K.  Because of this, I am using
the QEMM at work on a Zenith 386/33 where I don't have the Jlaser or a
Logitech mouse. :-)

If anyone has any questions about my experiences with the two
products, drop my a line and I'll be happy to answer any questions.
