Radius XGA-2 Windows 3.X Device Drivers Release 1.00 ==================================================== This file contains installation instructions and other general information on the Radius XGA-2 Windows 3.X device drivers. Driver Installation Instructions -------------------------------- This assumes Windows is already installed and that this is the first time you are installing the driver. If you have already installed your driver once and you wish to change the resolution of your display, please see the section below entitled "Changing your XGA resolution". Note: The Radius XGA-2 DOS install program should be run before installing the Windows drivers to set up the proper DMQS information for your display. To run the DOS install, type "A:\INSTALL" while at the DOS prompt. 1) Install Windows for VGA 2) Under the "File" menu of the program manager, choose "Run". 3) In the dialog box, type "A:\INSTALL". 4) A Dialog box will appear to select the desired resolution, when you have selected the proper resolution press the "Install" button. All necessary files are copied to the hard disk and the SYSTEM.INI and WIN.INI files are updated. 4) Several files, along with drivers for the resolution modes will be copied over to the WINDOWS\SYSTEM directory. You will then be asked to "restart Windows". Windows will restart in the resolution selected during the installation. Changing Your XGA Resolution (Windows 3.1) ------------------------------------------ Once you have installed your XGA device driver, Windows Setup will allow you to change resolutions from inside the Windows environment. 1) While running Windows, click on the Windows 3.1 SETUP Icon. Now select Options, then Change System Settings. 2) Click on the down arrow next to the Display box and you will see a list of installed drivers. 3) You are directed to select one of the following: Radius XGA-2 v2.02 640*480 256 Color Radius XGA-2 v2.02 640*480 65536 Color Radius XGA-2 v2.02 800*600 256 Color Radius XGA-2 v2.02 800*600 65536 Color Radius XGA-2 v2.02 1024*768 Small Fonts Radius XGA-2 v2.02 1024*768 Large Fonts Radius XGA-2 v2.02 1024*768 XLarge Fonts Radius XGA-2 v2.02 1280*960 Radius XGA-2 v2.02 1280*1024 Radius XGA-2 v2.02 1360*1024 Select the resolution you desire taking into account the capabilities of your display. It is recommended that the 1024x768 Extra Large Fonts option is only used for displays of 15 inches or smaller. 4) Click the OK icon. Windows will tell you that a driver for this display is already on the system. Select Current to keep your existing driver and change the resolution. 5) Click Restart Windows to immediately change your resolution, or Continue to change your resolution the next time you run Windows. Changing Your XGA Resolution (Windows 3.0) ------------------------------------------ To Change screen resolutions under Windows 3.0, you must first change the display driver to VGA using the Windows Setup Program. Then follow the instructions starting at #2 under "Driver Installation Instructions" above. Windows/Setup Problem Guide --------------------------- 1) While running Setup from within Windows, a General Protection Fault is generated. - Exit Windows and attempt to perform the same operation by running the Setup program from the DOS command prompt in your Windows subdirectory. 2) After running Setup, your XGA resolution is incorrect. - Check that your Display and XGA subsystem are capable of the resolution you have selected. - Check that your DMQS profile Display selection includes an option for the resolution you have selected. See your DMQS documentation for further details. - Sometimes Setup will not update certain settings in the SYSTEM.INI file correctly. Using a text editor, examine the file SYSTEM.INI in your Windows subdirectory. Look for the section headed by [XGA_DISPLAY] and check the entry for your resolution in the list below. Selection : Radius XGA-2 v2.02 640x480 256 Color SYSTEM.INI entry : XGA_Resolution=1 XGA_Resources=1 Selection : Radius XGA-2 v2.02 640x480 65536 Color SYSTEM.INI entry : XGA_Resolution=3 XGA_Resources=1 Selection : Radius XGA-2 v2.02 800x600 256 Color SYSTEM.INI entry : XGA_Resolution=4 XGA_Resources=1 Selection : Radius XGA-2 v2.02 800x600 65536 Color SYSTEM.INI entry : XGA_Resolution=5 XGA_Resources=1 Selection : Radius XGA-2 v2.02 1024x768 Small Fonts SYSTEM.INI entry : XGA_Resolution=2 XGA_Resources=1 Selection : Radius XGA-2 v2.02 1024x768 Large Fonts SYSTEM.INI entry : XGA_Resolution=2 XGA_Resources=2 Selection : Radius XGA-2 v2.02 1024x768 XLarge Fonts SYSTEM.INI entry : XGA_Resolution=2 XGA_Resources=2 Selection : Radius XGA-2 v2.02 1280x960 SYSTEM.INI entry : XGA_Resolution=6 XGA_Resources=2 Selection : Radius XGA-2 v2.02 1280x1024 SYSTEM.INI entry : XGA_Resolution=8 XGA_Resources=2 Selection : Radius XGA-2 v2.02 1360x1024 SYSTEM.INI entry : XGA_Resolution=7 XGA_Resources=2 3) When running Windows, garbage appears on the screen or Windows locks up the system frequently. Some PC Compatibles are incapable of supporting busmastering properly, which is the default for the XGA Windows drivers. To disable busmastering do the following: Using a text editor, examine the file SYSTEM.INI in your Windows subdirectory. Look for the section headed by [XGA_DISPLAY] and change the XGA_NoBusMaster=0 variable to XGA_NoBusMaster=1. 4) When running Windows, most of the desktop is garbage but the icons are legible. This is caused by computers which shadow the video ROM. Because the XGA Coprocessor registers reside at the end of video ROM,the XGA video ROM should not be shadowed. Look in the users manual for your computer to find out how to disable video ROM shadowing. It can usually be disabled through a setup program which can be entered at bootup by hitting a key like "F2". The XGA video ROM resides at C0000h-C8000h by default. 5) Unable use certain resolutions. The SetDMQS program in your RADXGA directory must be used to set the proper DMQS definitions for your display. If you do not have a RADXGA directory, run the install program on the Radius XGA-2 driver disk from the DOS prompt. 6) When changing from the Extra Large Fonts Driver to a Large Fonts Driver, the fonts stay extra large. The Setup program in Windows does not properly change from Extra Large to Large. To get the proper fonts, use the setup program in the Windows directory while at the DOS prompt. Video Device Conflict errors with EMM386 or other Expanded Memory Managers -------------------------------------------------------------------------- This problem occurs in particular on the IBM PS/2 Model 90, with integral XGA. It has become more prevalent since DOS 5.0. Instructions for EMM386 configuration to prevent EMM386 from conflicting with XGA are given here. This problem is caused by the EMM386.SYS or EMM386.EXE incorrectly attempting to appropriate the XGA adapters memory mapped registers region for its expanded memory or upper memory management. When the XGA driver attempts to claim access rights to its own memory mapped registers, Windows detects that this area of system memory has already been claimed by EMM386, and the result is a Video Device Conflict error. The EMM386 X= option can be used to tell EMM386 what areas to avoid. Proceed as follows : 1) Run the System Configuration Program and select Display Memory Map. On some systems this is done by pressing Ctl-Alt-Ins when the text cursor moves to the right side of the display during a re-boot. Alternatively, the System Configuration Program is run from the System Reference Diskette. To display the memory map, select Set Configuration, and then select Display Memory Map. On some systems the memory map will specifically refer to XGA or XGA-2. On others, such as the PS/2 Model 90, the allocation will be described as "Built in Features". Identify the area of System Memory reserved for the XGA Video Adapter, (for instance 8K at C600). 2) Modify the EMM386 invocation in CONFIG.SYS, and add the following option: X=C600-C7FF (for example) So that the line now reads (for example) DEVICE=EMM386.EXE NOEMS X=C600-C7FF Replace C600-C7FF by the actual location figures for your XGA Video Adapter, as found in Step 1. If you have a memory manager other than EMM386, proceed as above but consult your memory manager documentation for details of how to exclude the required memory area. Problems beyond our control --------------------------- 1) Text truncated in (menu) text boxes With the Extra Large system fonts in particular, but sometimes with the other system fonts, applications have not built sufficient tolerance to handle legitimate variations in system font size, and as a result some text boxes contain truncated text. This is an application problem, not a driver problem, as the application is responsible for querying the size of the text, and generating a sufficiently large box to surround it. Applications that have failed to build in a sufficient tolerance of device driver system font size variations will exhibit this problem. However in many cases, selection of a smaller driver system font may be a solution. See "Device Driver Installation Choices" for a description of how the various selections affect driver system font size. 2) CodeView under Windows corrupts the screen, eventually fails. CodeView does not run correctly with the XGA Windows driver. Points to Note -------------- 1) The XGA adapter card can not be used as a replacement for the 8514/A when running CVW (CodeView for Windows) on a PS/2. 2) Switching to a full screen DOS session while printing from a Windows application can cause information to be omitted from the printout. To avoid this problem, wait for the dialog box informing you that the file is being sent to the printer to be removed from the screen, before switching to the DOS session. Alternatively, run your DOS session in a window and the problem will not occur. 3) Screen print using the 'Print Screen' key is not possible. 4) A few applications can give different colors when run on the XGA as compared to the VGA. This results from different palette formats. 5) A blank screen is usually the result of trying to use the display adapter with no display attached. Ensure that the monitor is plugged into the XGA Adapter.
