Radius XGA-2 Color Graphics Card Release 1.00
=============================================
TOPIC: Radius DMQS Configuration Utility (SETDMQS.EXE) & DMQS
(Display Mode Query/Set) Profile Services.
I. Radius DMQS Configuration Utility User's Guide
A. Purpose of Tool
The purpose of the Radius DMQS Configuration Utility (SETDMQS.EXE)
is to install display information files onto a computer system
that supports DMQS and will be running an XGA graphics application
that will be using the DMQS support services to initialize the
XGA Adapter/Display hardware environment.
Below are the steps involved with running the setup tool
as well as a description of how the data that is installed by the
installation is used by other applications:
1. Unpacking/Copying DGS files.
The Radius XGA-2 installation program unpacks all of the
display information files from a supplied packed file.
2. Updating DOS and OS/2 system boot files.
In addition to installing the display files, the installation
tool will also update the system boot files on the user's
system hard-disk.
The DMQS services must have a system environment variable defined
in order to tell it where to look for the display information files
it needs to initialize the XGA Adapter/Display properly. The
setting of this environment variable must be done within the
system boot file. Thus, the installation tool will automatically
update the system file(s) found in the root directory of the
start up hard-disk in order to properly set the environment to
point to the installation directory specified during installation.
3. What are the MONxxxx.DGS files used for?
The DGS files in the file name form of MONxxxx.DGS will be used
by the DMQS system services in order to initialize the XGA Adapter/
Display configuration properly. Without the DGS file, the DMQS
services would not be able to determine what type of display is
attached to the system and what display capabilities the display
has.
B. Starting the Radius DMQS Configuration Utility
1. Setup Tool requirements.
a. Radius DMQS Configuration Utility files:
- README.TXT (This information file)
- SETDMQS.EXE (Radius DMQS Configuration Utility)
- MONxxxx.DGS (Unpacked XGA Display Information Files)
b. Starting the Radius DMQS Configuration Utility.
To start the Radius DMQS Configuration Utility select the "DMQS
Support (Monitor Configuration)" option from the Radius XGA-2
installation program menu.
2. Obtaining help in using the setup tool.
The Radius DMQS Configuration Utility tool has on-line help
services whereby one can depress the F1 key in order to get help.
II. XGA/DMQS Display Information File Profile Services.
The DMQS profile services found in the DMQS system services will allow
one to customize the XGA Adapter/Display environment found on a computer
system.
A. How to create an XGA Display Configuration Profile:
When you first install the XGA Display Information Files on your
system, a profile will be created and the XGA Graphics program that
uses the DMQS services will be provided with the default POST startup
DMQS values. However, you can override some of the DMQS values via
the XGA Display Configuration Profile mechanism.
The Radius DMQS Configuration Utility creates the DMQS Profile when you
select "Save Settings and Exit".
B. How the DMQS profile services work:
The DMQS profile services will look for a file by the name of
XGASETUP.PRO found in the same directory that has the Display
Information Files (MONxxxx.DGS).
This file is a ASCII text file which contains a set of GML tags that
will be used to provide information to the DMQS system services about
the XGA Adapter/Display environment. This profile allows one to
override some attributes of how the XGA hardware will be initialized
and used by graphics applications which use the DMQS system services.
C. Syntax and content of XGASETUP.PRO:
The file XGASETUP.PRO will be found in the same directory as the
Display Information Files which are installed by the XGA Display
Information File Installation Tool (the default path is XGA$DMQS).
This ASCII text file will contain a set of tags which define
attributes of the XGA Adapter/Display hardware installed.
Below is an example XGASETUP.PRO profile:
/**********************************************************************
/*
/* FILENAME: XGASETUP.PRO
/*
/* DESCRIPTION: Profile to set XGA DMQS preferences on current system.
/*
/* LAST MODIFIED: 03/29/92 at 10:57:37
/*
/**********************************************************************
/**********************************************************************
<SLOT, NUMBER=5, MONITOR_ID=00F0>IBM 8514
/**********************************************************************
<SLOT, NUMBER=8, MONITOR_ID=F0FF>IBM 8515, 8516
/**********************************************************************
<STARTUP, NUMBER=5>
The profile above does the following:
────────────────────────────────────
> Informs the DMQS services that the display in slot 5 is a display
of type 00F0 and that DMQS should use the display file MON00F0.DGS
to obtain information about the installed display.
> Informs the DMQS services that the display in slot 8 is a display
of type F0FF and that DMQS should use the display file MONF0FF.DGS
to obtain information about the installed display.
> Informs the DMQS services that when any XGA graphics application
uses DMQS services that the application will display its graphics
output on the XGA adapter card in slot 5.
NOTE: If any of the slot numbers and/or display IDs are invalid when
read in by the DMQS profile services, then the tag will be
ignored and it shall not have any affect on how the DMQS services
initializes the XGA hardware.
TOPIC: Radius XGA-2 Diagnostic (DIAG.EXE)
This utility provides diagnostic tests for the Radius XGA-2 Interface
card. It can also be used as a troubleshooting tool if you suspect a
problem, and to help resolve conflicts with other display adapters in
your system.
TOPIC: Font Corruption Fixup TSR (FONTSWAP.COM)
This TSR corrects possible font corruption when using host-based
applications such as a 3270 emulator that uses the Adapter Interface
(AI) to switch between test and graphics modes. The fonts become
corrupted because IBM originally designed the AI for the 8514/A
Display Adapter, which used separate memory for text (VGA) and
graphics modes. Since the XGA-2 interface uses the same memory for
both text and graphics modes, the area in memory where the fonts
are stored can become corrupted. If you are not using the AI, there
is NO reason to have FONSWAP.COM loaded as a TSR.
TOPIC: Value Point Fixup Utility (VPXGA.EXE)
This utility changes a value in the CMOS of IBM PS/ValuePoint machines
to allow the proper functioning of the the Radius XGA-2 Color Graphics
Card. It doesn't affect non-IBM systems and is run automatically by the
Installation program.
