OS/2
----
These drivers are designed to function with the OS/2 Version 3.0
operating system.
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 CHIPS 65548 Display Driver Diskette in drive A.
Type A: <ENTER> to make this the default drive.
Type INSTALL A: C: <ENTER>
where A: is the floppy disk drive and
C: is the hard disk partition containing \OS2
Once the Install Program is completed, do a system shutdown and
reboot.
A log of the information output during the install can be found
in <root>:\OS2\INSTALL\CTINSTL.LOG
Step 3: After the system has rebooted, open the System Setup folder
and run Selective Install to install the new device driver
and configure the video system.
Follow the instructions on the screen (see Note) to set up the OS/2 display
drivers in your system. First, select Primary Display from the System
Configuration Window. From the list of Primary Display Adapter Types,
select Chips and Technologies 65548 and then select OK.
Note:The proposed Path C:\OS/2\OS2IMAGE must be changed to A:\, insert the E.V.D. C&T video drivers PCI diskette and confirm with OK.
After the install program has completed, the display driver will be
initialized for 640x480x256 Color. Shutdown and then reboot the system
for the installed changes to take effect.
To switch to a different video resolution or color depth, do the
following:
Change Video Resolution
=======================
Step 4: To change the screen resolution or color depth:
Open the System Setup folder, then open System. From the list
of available screen resolutions, select a new resolution. Point
to the title-bar icon and double click. See Changing Screen
Resolution in OS/2 Users Guide for more information.
The system must now be shut down and restarted for changes to take
effect.
NOTE: Always use the INSTALL.CMD for the FIRST installation of the video
device drivers. Thereafter, to change video resolutions, do Step 4
above.
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.
