OS/2
----
These drivers are designed to function with the OS/2 Version 3.0 and 2.1x
operating systems.
Hardware
--------
These drivers support Chips & Technologies 65545 and 65548 graphics chips
in a PCI Bus configuration.
Driver Installation
===================
Before installation of this display driver, the system display should be set
to VGA mode. VGA is the default video mode enabled when OS/2 is installed.
If the current system primary display is not VGA, or if a previous version of
this driver is being used, the system should first be returned to VGA mode.
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.
To install this driver, do the following steps:
Step 1: Open an OS/2 full screen or windowed session.
Step 2: Place the 65548/545 PCI Display Driver Diskette in drive A.
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
Once the Setup Program is completed, you will need to 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
Step 3: After restarting the system, perform the following steps:
1. Open the System Setup folder.
2. Open the Display Install Object
These steps will execute the Display Driver Installation ( DSPINSTL )
utility program to finish installation of the new drivers.
3. Follow the instructions on the screen to select the OS/2 display
driver in your system.
Select Primary Display from the System Configuration Window.
Select Chips and Technologies 65548/545 PCI from the list of
Primary Display Adapter Types.
After the install program has completed, you will need to shutdown and then
restart the system for the changes to take effect.
The display driver will be initialized for 640x480x256 Color.
To switch to a different video resolution or color depth, follow the steps
below.
Change Video Resolution/Refresh Selection
=========================================
Step 4: To change the screen resolution/color depth, or screen refresh rate
do the following:
1) Open the System Setup folder.
2) Open the System Object.
3) From the list of available screen resolutions, select a
resolution.
From the list of screen refresh rates, select a refresh value.
Point to the title-bar icon and double click. This will close
System Settings and save your selection.
See Changing Screen Resolution in OS/2 Users Guide for more
information.
The system must now be shut down and restarted for the changes to take
effect.
WIN-OS/2
========
Please note the following limitations regarding WIN-OS/2.
1. The WIN-OS/2 full screen session should be set to Enhanced
Capability. The default setting is Standard Mode. If this setting
is not changed, Windows will not run correctly.
2. WIN-OS/2 should be started by selecting the WIN-OS/2 Full Screen
Icon in the Command Prompts folder, or with the WIN command in a DOS
Full Screen or OS/2 Full Screen session.
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.
Driver 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, follow these instructions:
Step 1: Copy all files on the OS/2 Display Driver Diskette as you
normally would onto another diskette.
Step 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.
