The QTEST Program


What is QTEST?

The QTEST program is provided at no charge to anyone interested
in finding out how QRAM 1.0, a product of Quarterdeck Office
Systems, will react on different systems. QRAM (pronounced
"cram") is intended to help you get more available memory below
640K by reducing DOS overhead, and by placing resident programs
and drivers that normally run below 640K into the unused areas of
memory between 640K and 1024K.

How is QTEST installed?

No installation is necessary; the file QTEST.COM may be run from
any available drive; even the disk on which it is supplied.
QTEST can be given the parameter HELP if you want to know about
the possible command line options.

Why is QTEST useful?

Unlike our other memory management products, QEMM-386 and
QEMM-50/60, QRAM is not a memory manager. It is instead a
program which USES expanded memory, video memory and/or shadow
RAM which MAY exist on your system. This memory is used by QRAM
to load resident programs and drivers into memory beyond 640K.

In environments where QEMM-386 or QEMM-50/60 would be
appropriate, these products provide ALL of the software support
necessary for using High RAM and increasing the available memory
below 640K. By reading the hardware requirements on the back of
our manuals, it is fairly easy to determine whether your system
meets the hardware requirements required for success.

But on 8088 or non-PS/2, 80286 based systems, where QRAM might be
appropriate, QRAM is dependent on both hardware and software
which has been provided by third party vendors. Given the right
software/hardware combination, QRAM can:

1. Load resident programs and drivers into EEMS or EMS 4.0
memory beyond 640K to increase your available DOS memory.

2. Load resident programs and drivers into Chips & Technology
Shadow RAM if it exists on your system. 3. Allow DOS to be
extended into your EGA or VGA video card memory when running text
based programs.

However, it may be difficult for the average user to determine
the exact capabilities of the available hardware and software
drivers.
With respect to the use of EMS 4.0 memory, even a sophisticated
user may have difficulty determining exactly how QRAM will be
able to use the memory on his machine. This is due to the fact
that EMS 4.0 is a fairly "loose" specification and that some
makers of EMS 4.0 hardware and software do not implement all of
the features of EMS 4.0 which are important to QRAM.

It was with these concerns in mind that Quarterdeck created QTEST
as a service to its prospective QRAM users.

QTEST will tell you what QRAM will be able to do on your system
in its current configuration, and will tell you whether (or not)
QRAM could be useful to you.

How do I get QTEST?

QTEST is available via modem at no charge (other than phone and
system charges) on the following systems:

1. Quarterdeck Bulletin Board, public files section, under the
name QTEST.ZIP. BBS phone number: (213) 396-3904.

2. Quarterdeck's Compuserve Forum. Type "GO PCVENB" from the
system prompt. QTEST is available in library #1 under the name
"QTEST.ZIP".

3. Quarterdeck's BIX Forum. Type "Join DESQview" from the
system prompt. Select "Receive" from the forum menu. The
filename is "QTEST.ZIP".

4. On various private bulletin boards which participate in the
DESQview SmartNET or FIDOnet echo.

QTEST is also included for no charge on our "Quarterdeck White
Papers" diskette, a collection of technical notes covering the
use of Quarterdeck products. The White Papers diskette is
available direct from Quarterdeck for $10 and can be ordered by
credit card by calling our orders department at (213) 392-9851. Copyright considerations:

Although QTEST is a copyrighted program, Quarterdeck grants to
you a limited license which permits you to distribute it to
others, on disk or electronically, as long as the program and its
documentation are not modified in any way, proper credit is given
to Quarterdeck, and no fee is charged beyond the cost of
materials.

Documentation for The Technical Information Screen:

Most of the output of QTEST is in plain English and does not
require documentation. Some explanation of the "Technical
Information" screen which is displayed after QTEST runs may be
useful however.

After it runs, QTEST displays a screen similar to the one below.

Memory Map if QRAM 1.0 is used

x = 048C
Ax00 ???? H = High RAM
Bx00 ???? M = Memory Fill
Cx00 ???? v = Vidram Use
Dx00 ???? F = Page Frame
Ex00 ???? X = Unusable
Fx00 ???? - = Hide

Each question mark shown above represents a 16K section of high
memory address space, in the range of 640K (A000 Hex) to just
under 1 Megabyte (FFFF Hex), which may be available to QRAM or
not, depending on the current configuration.

In your QTEST output, each question mark will be replaced by one
of the characters from the table on the right, indicating the
current status of that particular memory location. Here's what
the characters mean:

{H = High RAM} - Each H is a 16K block into which QRAM could load
a resident program or driver.

{M = Memory Fill} - Each M is a 16K block into which QRAM could
extend DOS to provide more memory for all programs. This occurs
when you have appropriate EEMS or EMS boards and CGA or
Monochrome video cards. {v = Vidram Use} - Each v is a 16K block into which QRAM's VIDRAM
utility could extend DOS to provide more memory for text based
programs. This is only available on EGA and VGA cards and only
when running text, as this same memory area is used for
displaying graphics.

{F = Frame} - Each F is a 16K block which is currently making up
part of the EMS Page Frame. The Page Frame is an area of memory
addresses where expanded memory is accessed by most programs.
All of the expanded memory can only be seen a little at a time;
the Page Frame is a "porthole" through which the expanded memory
is accessed. Page Frame memory is not normally available to
QRAM, but could be used if QRAM were loaded with the
FRAMELENGTH=0 parameter. This disables expanded memory, but
makes the 64K area available to QRAM. On some EMS boards this
may be your only option.

{X = Unusable} - Each X is a 16K block, which due to other
installed hardware, or limitations of your hardware or software
cannot be used at all by QRAM.

{- = Hide} - These are sections of your expanded memory which
appear to have been made available by your expanded memory
driver, but in which QRAM detects a conflict with other installed
devices. In these conditions, it hides the memory so that it
will not be used by QRAM or other expanded memory utilities.
This can be overridden by QRAM's INCLUDE parameter if it is
determined that QRAM is incorrect about the conflict. When
overridden, these areas become HIGH RAM.

What QTEST cannot detect:

QTEST tests your system in its "current configuration". It
cannot determine how your system would react if set up
differently. If you have a system which you believe to have
Chips & Technology shadow RAM and QTEST does not see the shadow
RAM, be sure that your shadow RAM has been enabled. If you are
loading an expanded memory driver which might be using up this
shadow RAM memory, try disabling it. If it turns out you have
usable shadow RAM, QRAM can be loaded before the expanded memory
manager and both could be used.

If you have an expanded memory board you believe should support
EMS 4.0 high memory areas in addition to the Page Frame, check
your board's manual to see if there are any adjustments in
software or hardware which must be made to enable this feature. QTEST also cannot determine which of your memory resident
programs,

device drivers, or pieces of DOS can be loaded into High RAM.
This is determined by QRAM's OPTIMIZE program. You can get some
idea of what might be loaded high by comparing the resident size
of your TSRs to the High RAM available. However, such programs
often require MORE memory to get started then they take up after
they have "squished" themselves into their final state. Some
could prove to be too large to load into high memory.

Therefore, it is difficult to tell exactly how much memory will
be saved below 640K in your system. Since QRAM's OPTIMIZE
program usually CAN find something to load into High RAM, the
most important thing to know is whether you can get High RAM.
This is what QTEST tells you.
