SECTION 1. Configuring EMS driver software
This information is intended to assist you in using the
documentation provided with your EMS driver software.
If you are not familiar with EMS, the Technical Notes in
the manual and tutorial will make the following material
more meaningful.
If you are already using EMS 4.0 with other software, you
should check your configuration by running the CHECKEMS
program on this disk. If the display shows just one line
below the "Mappable high memory" heading and the size
exceeds 64K, you have a user friendly driver and need not
read any further in this section.
To use PopLoad to full advantage you will want the largest
possible "Page Frame" i.e. mappable high memory area. For
some EMS drivers this is the default. Others require that
options be specified when the driver is loaded from the
config.sys file. These drivers typically default to the
minimum EMS 4.0 page frame size of 64K and use the highest
available 64K in high memory.
To increase the page frame size you specify a lower address
for the page frame start address and that space beyond the
default 64K is to be included. You specify these options
by adding codes to the line in your config.sys file that
loads the EMS driver. For example, the line could read as
shown below where SSSSS and IIIII override the driver's
defaults for the start address and add to page frame size.
device = [d:][path][filename.sys] SSSSS IIIII
For the format used to specify these options you must refer
to your driver documentation. In the example below the
"frame=" and "include=" are part of the notation used by
some drivers. The aaaa, bbbb and cccc are hexadecimal
addresses defining the page frame start address and an
address range to be included.
EXAMPLE SSSSS IIIII
frame=aaaa include=bbbb-cccc
The driver documentation and the memory mapping utility
programs included with many drivers will guide you in
selecting the addresses to use.
When you have changed the options, power off and on to
install the driver. A cold boot is recommended as some
drivers determine the memory configuration from data which
remains in memory through a warm boot.
You should then run the CHECKEMS program on this disk to
view the memory statistics it obtains from the driver. The
page frame size reported must equal or exceed the EMS 4.0
64K minimum or PopLoad will refuse to load.
SECTION 2. Notes on specfic EMS drivers
AST REMM.SYS
A problem can arise using older versions of the driver for
the AST Premium 286 if the default page frame conflicts
with the address space used by a network or other adapter
installed in your machine.
To deal with this, you need the latest version of the
driver (REMM43.SYS) as earlier versions do not support all
the options required. Specify the address space to exclude
and the page frame start address as described in the AST
manual with the /X= and /S= options. Using /S= produces
only a 64K page frame. You can extend the page frame to
the maximum size with the /L= option. The format is
/L=aaaa-bbbb where aaaa is the address following the page
frame and bbbb is the highest available (usually EFFF).
Current versions of AST drivers are available free from AST
or by downloading from the AST BBS. (714) 852-1872
COMPAQ 386 CEMM.EXE
The Compaq CEMM.EXE LIM 4.0 driver is included on the disks
in the Compaq MS-DOS for the 386 series. Documentation for
the driver is found in a separately priced manual which
covers supplementary programs. The essential parameters on
the config.sys command are: "nnn Mn" The nnn specifies the
page frame size in Kbytes. M1 specifies a page frame start
address of C000, M2 specifies C400 etc. For a 128K page
frame starting at C000 the load command options would be,
"128 M1"
IBM DOS 4.0 XMAEM.SYS-XMA2EMS.SYS
The reported bugs in the EMS 4.0 driver software supplied
in IBM DOS 4.0 were not encountered in testing with these
updated versions available from IBM dealers: XMAEM.SYS
(3-29-89) and XMA2EMS.SYS (4-06-89).
Users of 386 based PS/2 machines should consider a third
party driver to escape the 64K page frame limitation and to
gain added features.
Intel Inboard-386 ILIM386.SYS
The version (with a file date of 2/13/89) appears to work
perfectly. An earlier version dated 10/28/87 does not.
Contact Intel for a copy of the new version. It is also
available on the Intel BBS. (503) 645-6275
Third Party Drivers
PopLoad has been tested with the third party EMS drivers
for 386 based machines listed below. Both provide
compatible EMS driver support. The Quarterdeck program
that provides memory statistics, incorrectly reports that
their driver is not loaded when our driver is also present.
The Qualitas driver does not have this problem and uses
less memory.

SECTION 3. Tips
Maximum TSR Size
TSR's may require more memory at start up than they occupy
when loaded. Thus, a TSR that would seem to fit may not
and PopLoad will display the message "Program size exceeds
largest high memory block." The same message is displayed
if a TSR attempts to load a file such as a dictionary into
memory and the combined requirement exceeds the available
space.
Shell Programs
PopLoad is designed to work only with TSR's and cannot be
used to load DOS shell programs such as Norton Commander
and Lotus Metro.
Disk Cache Programs
As noted in the manual, PopLoad is not compatible with disk
cache programs using EMS. Most cache programs allow you to
specify use of extended rather than expanded memory.
