What this package contains:
===========================
This package contains new video device drivers for use with
Windows 3.1 (tm) & some DOS application programs, such as
WordPerfect (tm) & AutoCAD (tm). These device drivers are
specifically designed to maximize performance & function of
these applications on the ThinkPad 350/350C & PS/Note 425/425C
systems.
This is version 2.5.1 of the device driver package, which
contains problem fixes & performance enhancements. Windows
users who install the driver recommended below (640x480 256
colors, linear version) will see significant performance
& appearance improvements over the default VGA driver.
This package contains images for 2 separate diskettes.
The following instructions will guide you through creating
the diskettes & installing the software.
You will need two 3.5" diskettes, formatted for 1.44 Meg.
Creating the diskettes:
=======================
1. Copy the AFVIDEO* EXE files to your hard disk as AFVIDEO1.EXE and
AFVIDEO2.EXE.
2. Format one or two 2MB diskettes to 1.44MB.
3. Self-extracting diskette images:
Example:
(with diskette in drive)
c:\AFVIDEO1 (will create diskette #1)
c:\AFVIDEO2 (will create diskette #2)
Label the diskettes as follows:
AFVIDEO1.EXE ==> ThinkPad 350, PS/Note 425 Video Drivers
for DOS & Windows 3.1 (tm)
Diskette 1 of 2
Version 2.5.1

==================================================================
YOU ARE STRONGLY ENCOURAGED TO WRITE PROTECT THESE DISKETTES &
PROTECT THEM AS YOU WOULD ANY OTHER ORIGINAL SOFTWARE DISKETTES.
==================================================================
Installing the software:
========================
The following procedure describes the Windows 3.1 (tm)
installation procedure (the procedure is similar for other
programs). There are 2 steps:
1. Copy the new video drivers to your fixed disk
(an installation program is provided for this purpose)
2. Tell Windows to use the new driver you prefer
(you will use a program provided with Windows to do this)
This procedure assumes that you have installed Windows using
the default directory names. If this is not the case, you
may need to override the subdirectory prompts when they are
presented by the installation program.
Copying new display drivers to your fixed disk:
-----------------------------------------------
1. Insert the AFVIDEO1 diskette into your system
2. Switch DOS prompt to A: drive - this **MUST**
be native DOS, not a DOS session opened from Windows !!!
3. Enter & execute "setup" (executing setup from A: disk)
4. Follow menu directions, with 2 important notes:
- select "Windows" drivers, "all resolutions"
- again, assuming Windows was installed with std dir names,
accept default destination for drivers
5. Escape when complete
Tell Windows to use the new drivers:
------------------------------------
1. Switch back to C: drive
(assuming standard Windows directory names) change to
C:\WINDOWS subdirectory if necessary
2. Enter & execute "setup" (executing setup from C:\WINDOWS)
After a few moments, a menu will be displayed with your
system current configuration
3. Cursor up to "Display" & hit enter
4. Select "* CHIPS 655XX Linear 640x480x256" driver from list
& hit enter (note: there will be other 640x480x256 drivers,
so be certain to pick the "Linear" variety)
5. You should now be back at the system configuration screen,
with the highlight on "Accept the configuration shown above".
Press enter.
6. Another screen will display showing details of the driver
which is about to be installed (name, size, version, date).
Press enter again & allow the install to complete.
At this point you should be back to the DOS prompt. You may
start Windows, will use the new driver. If you've chosen the
driver recommended above, you will see a message after the Windows
logo is displayed, & before the Windows desktop appears:
"Welcome to the CHIPS linear 8BPP driver 2.51"
NOTE: if you use a virus protection program, you may get a
warning message when you start Windows, since WIN.COM has been
changed. Most virus protection software will allow you to
OK an update to the record for this file.
Known Problems:
===============
1. Starting Windows when the display device is set to "CRT"
(see Configuration Utility, Fn+F1):
Windows logo will display OK, CHIPS driver signon will display
OK, then desktop will not display properly (loss of sync).
This problem only occurs when display device is set to "CRT".
"LCD" & "LCD and CRT" function properly.
WORKAROUND: Press Fn+F1 to enter Configuration Utility, then
Esc to exit. Display will be re-synchronized.
ALTERNATE: Use "LCD and CRT" display device setting when
CRT use is required.
2. Entering Configuration Utility from DOS session under Windows
when display device is set to "CRT":
Screen sync is lost when returning from Configuration Utility.
This problem only occurs from a DOS session under Windows
(does not affect native DOS) when the display device is set
to "CRT". "LCD" & "LCD and CRT" will function properly.
WORKAROUND: Issue a "mode co80" command to re-synchronize
the display.
ALTERNATE: Use "LCD and CRT" display device setting when
CRT use is required.
