Title: VO701322.DOC
Date: 96/01/15
Version: 3.22
==================================================================
PLEASE READ THIS FILE BEFORE BEGINNING THE DRIVER INSTALLATION.
==================================================================
What this package contains:
===========================
This diskette contains the Chips & Technologies 65545 Drivers
for OS/2 2.1x & WARP on IBM ThinkPad models 701C & 701CS. Do
not use these drivers on any other systems. These device drivers
are specifically designed to maximize performance & function of
OS/2 on the ThinkPad 701C & 701Cs systems.
This is version 3.22 of the device driver package. OS/2 users
installing one of these drivers will see significant performance
& appearance improvements compared to the default VGA driver.
This package contains one diskette image. The following
instructions will guide you through creating the diskette
& installing the software.
You will need one 3.5" diskette, formatted for 1.44 Meg.
Creating the diskettes:
=======================
1. Download the VO701322.EXE file to your workstation
in binary mode (WITHOUT character translation or line feed
& carriage return insertion).
2. Format one 2MB diskette to 1.44MB.
3. Use LOADDSKF to create the new diskette:
Example:
LOADDSKF VO701322.DSK A:
LOADDSKF can be obtained from IBM separately.
==================================================================
YOU ARE STRONGLY ENCOURAGED TO WRITE PROTECT THIS DISKETTE &
PROTECT IT AS YOU WOULD ANY OTHER ORIGINAL SOFTWARE DISKETTE.

Features
========
1. Windows (tm) programs can be run in "seamless" fashion with these
drivers. You can also run Windows applications in fullscreen mode
if you prefer.
To change session type: click right mouse button (assuming right-
handed mouse setup) on object to display options menu. Click on
arrow on 'Open' line, to display Open options list. Click on
'Settings' to open settings notebook. Click on 'Session' page tab
to display session type options. Choose fullscreen or windowed
session type.
2. When using a display driver resolution greater than 640x480, with
the display device set to "LCD" or "LCD and CRT", the driver will
only show a 640x480 "window" of the larger desktop. This "window"
will move automatically when you move the mouse pointer against
the edge of the screen, allowing you to slide the 640x480 "window"
to view any portion of the larger desktop.
This feature is called "panning", & it eliminates the need to
reconfigure OS/2 when switching between a high resolution monitor
and the internal LCD display. When you change the display device
to "CRT", you will see the entire 800x600 or 1024x768 mode you
have selected.
Please make certain your external monitor will support the high
resolution modes before switching the display device to "CRT"
(only).
3. 640x480x16M colors are supported.
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.
Installation of Chips & Technologies 655XX Drivers for OS/2 WARP
================================================================
*************************** Warning ******************************
Before installation of any SVGA display driver, the system display
should be set to VGA mode. DO NOT install this driver package if
the system display is set to anything other than 640x480x16 VGA
mode. To restore VGA mode, use Selective Install and select VGA
for Primary Display, or run the SETVGA utility.
******************************************************************
Step 1: Open an OS/2 full screen or windowed session.
Step 2: Place the CHIPS 65545 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, do the following depending on
which version of OS/2 is installed:
A) OS/2 2.1x
Open an OS/2 full-screen or windowed session. At the OS/2
prompt, type DSPINSTL <ENTER> to install the new device
driver and configure the video system.
B) OS/2 Version 3
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 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 65545 and then select 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.
The command file will copy the following files to C:
C:\OS2\SVGA.EXE -- original saved as SVGA.ESV
C:\OS2\INSTALL\DSPINSTL.EXE -- original saved as DSPINSTL.211
-- this file NOT copied on WARP
C:\OS2\SCREEN01.SYS -- original saved as SCREEN01.SSV
(if present - otherwise you may
see the message, "File Not Found" -
this is OK)
C:\OS2\MDOS\VSVGA.SYS
C:\OS2\CHIPS.SYS
C:\OS2\INSTALL\CT65545.DSC
The command file will also run SETLBA.EXE which will modify
CHIPS.SYS with this adapter's linear buffer address obtained
from BIOS.
