- 4.0 Driver Installation
- -----------------------
-
- 4.1 Preliminary Steps
- ---------------------
-
- The following steps must be performed before you install the 65545/65548
- display driver:
-
- 1. OS/2 DOS Support must be installed.
-
- 2. If you previously installed SVGA support, you must do the following:
-
- a) Close all DOS Full Screen and WIN-OS2 sessions.
-
- b) Reset the system to VGA mode. VGA is the default video mode enabled
- when OS/2 is installed. To restore VGA mode, use Selective Install and
- select VGA for Primary Display. For more information on this procedure,
- see the section on Changing Display Adapter Support in the OS/2 Users
- Guide.
-
-
- 4.2 Installing from Diskette
- ----------------------------
-
- To install this driver, do the following steps:
-
- 1. Open an OS/2 full screen or windowed session.
-
- 2. Place the 65545/65548 VL/ISA Display Driver Diskette in drive A.
-
- 3. At the OS/2 command prompt, type the following commands to
- copy the files to the OS/2 drive:
-
- Type A: <ENTER> to make this the default drive.
-
- Type SETUP A: C: <ENTER>
-
- where A: is the floppy disk drive and
- C: is the hard disk partition containing \OS2
-
- When the Setup Program is completed, you will need to perform a shutdown
- and then restart the system in order for changes to take effect.
-
- A log of the information output during the install can be found
- in <root>:\OS2\INSTALL\DISPLAY.LOG
-
- 4. After restarting the system, perform the following steps:
-
- 1. Open the OS/2 System folder.
-
- 2. Open the System Setup folder.
-
- 3. Open the Display Driver Install Object
-
- This step will execute the Display Driver Installation ( DSPINSTL )
- utility program to finish installation of the new drivers.
-
- 4. When the Display Driver Install window appears, select Primary Display
- and then select OK.
-
- 5. When The Primary Display Driver List window appears, select
- "Chips and Technologies 65545/548 VL/ISA" from the list of adapter
- types, then select OK to install the video driver.
-
- 6. When the installation is complete, you will need to shutdown and then
- restart the system for the changes to take effect. Make sure to remove
- the install diskette before restarting the system.
-
- When the system has restarted, the display driver will be initialized for
- 640x480x256 Color, 60Hz refresh. To switch to a different video resolution
- color depth, or refresh rate, follow the steps below.
-
- 4.3 Selecting Monitor Type
- --------------------------------------------
-
- Monitor type is initially set to DEFAULT. This DEFAULT setting may not allow
- you to select all resolution/refresh combinations that are available for your
- monitor. The following steps can be done to select monitor type. This section
- applies only after installation, or when a different monitor is used.
-
- 1. Open the OS/2 System folder.
-
- 2. Open the System Setup folder.
-
- 3. Open the System object.
-
- 4. When the System - Settings notebook appears, select the Screen tab.
- This will take you to page 2 of the settings.
-
- 5. On Screen page 2, select your monitor type from the Display Name
- list. If your monitor is not listed, select DEFAULT. Return to
- Screen page 1.
-
- It may be necessary to restart your system to have all refresh rate
- options available.
-
- 4.4 Selecting Screen Resolution/Refresh Rate
- --------------------------------------------
-
- To switch to a different video resolution, color depth or refresh rate,
- follow the steps below.
-
- 1. Open the OS/2 System folder.
-
- 2. Open the System Setup folder.
-
- 3. Open the System object.
-
- 4. From the selection windows provided, select a new Screen Resolution
- and Screen refresh rate.
-
- Please note, Refresh rates, other than 60Hz, are only valid when
- the display is switched to CRT only display mode.
-
- 5. Close the System-Settings notebook.
-
- 6. Perform a shutdown and restart for the changes to take effect.
-
-
- 4.4 Installation Notes
- ----------------------
-
- 1. During the installation of this driver, DISPLAY.LOG and DSPINSTL.LOG files
- are created in \OS2\INSTALL directory. These files identify the OS/2 system
- files that were updated and indicate whether the install was successful.
- The DISPLAY.LOG file also contains a string which identifies the version of
- driver that was installed. This information may be important when reporting
- an installation problem.
-
- 2. During installation, DSPINSTL will invoke the SVGA Configuration program
- SVGA.EXE to determine the hardware configuration, and create the file
- \OS2\INSTALL\SVGADATA.PMI. If this file is not created, the adapter will
- not be supported. When this step is done, the display will be blanked, and
- you may see a series of flashes on the display, and what appears to be a
- "corrupted" display. This is normal, as the configuration process is doing
- Video BIOS mode sets to determine which screen resolutions BIOS supports.
- This configuration information is then used to provide the System-Settings
- Resolution and Refresh selections.
-
- 5.0 WIN-OS/2 Sessions
- ---------------------
-
- Please note the following limitations regarding WIN-OS/2.
-
- 1. It is recommended that the user start all WIN-OS/2 sessions via one of the
- WIN-OS/2 icons in the Command Prompts folder.
-
- 2. The WIN-OS/2 session settings for both WIN-OS/2 Full Screen and WIN-OS/2
- Window should be set to Enhanced Capability. The default setting is
- Standard Mode. If this setting is not changed, Windows will not run
- correctly. To make this change, do the following:
-
- 1. Open the OS/2 System Folder.
- 2. Open Command Prompts Folder.
- 3. Place the mouse pointer over WIN-OS/2 Full Screen ( or WIN-OS/2 Window )
- icon and press mouse button 2 ( right button) to bring up the menu.
- 4. Select Settings.
- 5. Place the mouse pointer over the Session tab, and select by pressing
- mouse button 1 ( left button ).
- 6. Place mouse pointer over Win-OS/2 Settings, and select by pressing
- mouse button 1 ( left button ).
- 7. From the Win-OS/2 Settings - Categories, select All DOS and WIN-OS/2
- Settings and then select OK.
- 8. From the list of settings that appear, make sure that
- WIN_RUN_MODE is set to Enhanced Capability, and then "Save" these
- settings.
-
- 3. Do not start WIN-OS/2 in a DOS or OS/2 Window. The system does
- not support the enhanced video mode being used in a window, and
- therefore will not run.
-
- 4. When running a full screen WIN-OS/2 session, do not use ALT-HOME to
- switch to Windowed DOS session.
-
- 5. The Windows SYSTEM.INI file may need to be modified to select the
- correct mouse driver for use on the target system. The default is
- MOUSE.DRV=MOUSE.DRV. Some manufacturers may use a different mouse driver
- than the default, and the driver may reside in a directory other than
- the Windows root directory. In SYSTEM.INI, you will find two statements
- that specify the filename of the current mouse driver, MOUSE.DRV= and
- OS2MOUSE.DRV= . Make sure that OS2MOUSE.DRV= specifies the same mouse
- driver and path as MOUSE.DRV= .
-
- Example: MOUSE.DRV=LMOUSE.DRV ; installed by Windows
- OS2MOUSE.DRV=LMOUSE.DRV ; installed by OS/2 Install
-
- If OS2MOUSE.DRV does not point to the correct mouse driver, then
- WIN-OS/2 Full Screen and WIN-OS/2 Window sessions will not run.
-
-
- 6.0 Installation Diskette Copy
- ------------------------------
-
- For proper installation of OS/2 drivers, all diskette copies must be properly
- labeled "CTDISP 1".
-
- To copy the OS/2 Display Driver Diskette, do the following steps:
-
- 1. Copy all files on the OS/2 Display Driver Diskette as you normally would
- onto another diskette.
-
- 2. Place the diskette copy in drive A. At the C:\ prompt,
- type LABEL A: CTDISP 1 to properly label your diskette. Then store
- your diskette copy in a safe place.
-
- 7.0 Installation on Merlin ( OS/2 4.0 )
- ---------------------------------------
-
- If you are installing these drivers on Merlin and you receive the following
- error message:
-
- "This fixpack is intended for OS/2 versions 4.00,3.01,3.00,2.11,2.10 only !"
-
- the install script has not correctly identified the Merlin version id. This
- will require editing SETUP.CMD on this disk to function correctly.
-
- Find the following source lines in SETUP.CMD:
-
- IF ERRORLEVEL 210 set dsc=%src%\prereqs.dsc&& set cfg=%src%\vcfginst.exe&& GOTO VER_WARP
- GOTO VER_NOT_OK
- :VER_MERLIN
- copy %src%\chipm*.dsc %trg%\os2\install\chips*.dsc >NUL
-
- Change these lines as follows:
-
- IF ERRORLEVEL 210 set dsc=%src%\prereqs.dsc&& set cfg=%src%\vcfginst.exe&& GOTO VER_WARP
- set dsc=%src%\prereqs.dsc
- :VER_MERLIN
- copy %src%\chipm*.dsc %trg%\os2\install\chips*.dsc >NUL
-
- The install will now default to Merlin, and the drivers will get installed
- correctly. Reference section 4.2 above and start install again.
