COMPATIBILITY
_____________
This device driver is compatible with OS/2 2.1 and
higher. Do not install it on previous versions of
OS/2.
PRELIMINARY STEPS
_________________
The following steps prepare your computer for the
WD90C24/31 graphics controller device driver:
1. You must have OS/2 DOS Support installed in order
to install this driver.
2. The OS/2 ATTRIB command is used during
installation of the device driver. If you
elected not to install the OS/2 Optional System
Page 5
Utilities or you have deleted the ATTRIB command,
use Selective Install and select Change File
Attributes to restore the ATTRIB command before
continuing.
3. If you previously installed SVGA support, return
to VGA resolution using the procedures in
"Setting Your Display to VGA Mode" later in this
README before you install this driver.
4. Be sure to copy the VESA program supplied with
your system or video adapter and update your
AUTOEXEC.BAT file to get support for high
resolution and high color modes.
If in the future you want to change your display, you
must perform the steps listed above again to
configure the display profile. Then you must issue
the SVGA ON command at a DOS command prompt to
recreate the SVGADATA.PMI file before you connect
your new display to the computer.

INSTALLATION FROM DISKETTE
__________________________
To install the WD90C24/31 device driver from
diskette, do the following:
1. Insert the WD90C24/31 diskette into drive A (or
any other diskette drive).
2. Open an OS/2 full-screen or OS/2 window session.
3. At the OS/2 command prompt, type the following
command to copy all necessary files to the OS/2
drive:
A:SETUP A: C:
(where A: is the diskette drive, and C: is the
drive where OS/2 is installed.)
Then press Enter.
4. When prompted to do so, remove the diskette from
drive A, perform a shutdown, and then restart
your computer.
5. Open the OS/2 System folder.
6. Open the System Setup folder.
7. Open the Display Driver Install object.
When the Display Driver Install window appears,
"Western Digital 90C24 [IBM BBS]"or "Western Digital 90C31 [IBM BBS]"
Page 7
should be the default choice. If not, select it.
Then select OK.
8. When the Monitor Configuration/Selection Utility
window appears, the "Install Using Defaults for
Monitor Type" choice is preselected. You can
accept this choice or select "Install Using
Display Adapter Utility Program" to choose a
different refresh rate. Then select OK.
If you select the "Install Using Display Adapter
Utility Program" choice, you must have a DOS
monitor utility that came with your display
adapter. Contact the display adapter
manufacturer's technical support for information
on how to use the monitor utility under OS/2.
9. When the Source Directory pop-up window appears,
insert the WD90C24/31 diskette into drive A.
Then select Install.
NOTE: At this point, DSPINSTL determines the
hardware configuration by creating the
\OS2\SVGADATA.PMI file. If the
\OS2\SVGADATA.PMI file has not been
created, the adapter will not be
supported.
10. When the installation is complete, do the
following:
Page 8
a. Open the OS/2 System folder.
b. Open the System Setup folder.
c. Open the System object.
When the Settings notebook appears, select
the Screen tab to see a list of all the
supported resolutions for your configuration.
d. Select a resolution. Then close the
notebook.
e. Perform a shutdown and restart your computer.
Note that during the installation of this driver,
DISPLAY.LOG and DSPINSTL.LOG files are created in the
OS2\INSTALL directory. These files identify the OS/2
system files that were updated and indicate whether
the installation was successful. The contents of
these files might be useful if you need to report an
installation problem to IBM.
Page 9
INSTALLATION IN A CID ENVIRONMENT
_________________________________
NOTES:
1. The server must contain a directory named WD_DRVS
on the same drive where the OS/2 diskettes
reside. The WD_DRVS directory must contain all
of the files from the WD90C24/31 device driver
diskette.
2. OS/2 must have been successfully installed on the
client using the CID (Configuration Installation
Distribution) method.
To install the WD90C24/31 device driver using CID,
use the following information to modify your LCU
command file.
NOTE: The following information is meant as a guide.
Your LCU command file might be different.

END OF LCU INFORMATION TO BE ADDED
/*****************************************************/
Following is an explanation of the line that is
executed in the LCU command file:
C:\OS2\INSTALL\DSPINSTL /PK:SVGA /SK:NONE /S:X:\
/T:C: /MC:4 /res:640x480x256
/PK:SVGA where SVGA is the primary adapter key.
/SK:NONE where NONE is the secondary adapter key.
/S:X:\ where X:\ is the redirected source path.
/T:C: where C: is the drive where OS/2 is installed.
/MC:4 is the manufacturing code that distinguishes Western Digital.
/res:640x480x256 is a resolution/color depth from the
list of "Supported Resolutions" that appears earlier in
this README.
NOTES:
1. Be sure you have the stated video memory
required, as listed in "Supported Resolutions"
earlier in this README. A safe choice is
640x480x256. Any of the listed resolutions can
be selected, but your display might be damaged if
you select a resolution that your display does
not support.
Page 14
2. After the WD90C24/31 device driver has been
successfully installed on the client machine
using the CID method and the client machine is
restarted, the resolution will be as specified by
command line argument.
FUNCTIONAL RESTRICTIONS
_______________________
o The WD90C24/31 driver does not support 16 million
color mode.
o To avoid a general protection fault while loading
Ventura Publisher** for Windows**, be sure it is
in one of the 256 color resolutions.
o WordPerfect** Versions 5.1 and 5.2 for Windows
produce a general protection fault when the
"Print Preview" option is selected while using
800x600x64K color mode.
o Users of the software motion video feature of
MMPM/2* should expect satisfactory results in
256-color modes. However, in 64K-color modes,
users of the feature will experience unusual
results. An OS/2 pervasive fix package will be
available electronically.
o Display Console Access Facility (DCAF) is
supported in 256-color modes only.
Page 15
o CorelDRAW** 2.0 will not run in a WIN-OS/2*
window session. It must be run in a WIN-OS/2
full-screen session.
o Micrografx** Charisma 2.1 will not run in a
WIN-OS/2 window session. It must be run in a
WIN-OS/2 full-screen session.
FUNCTIONAL RESTRICTIONS FOR LAPTOP COMPUTERS
o To change refresh rates on the ThinkPad, edit the
file called IBMVESA\FRATE.DAT. See
IBMVESA\TPADVESA.DOC for instructions on how to
edit this file.
o On laptop computers with Super-Twisted Nematode
(STN) display, even though 1MB video memory is
shipped with the system, only 0.5MB is
addressable by the software. The other 0.5MB is
used internally by the controller. This will,
therefore, restrict the number of supported
resolutions. Most laptops with STN panels have
model numbers ending with "S."
o Many laptops have a built-in internal display
capable of only a 640x480 resolution when used
during transportation or at remote sites.
However, when connected to an external display at
the office, these systems are capable of 800x600
and 1024x768 resolutions.
Page 16
To avoid the need to select the lower resolution
prior to leaving the office, the OS/2 device
driver for the WDC24 automatically detects when
the internal display is ON and sets the lower
resolution (even though a higher resolution is
shown as selected on the Screen page of the
System Settings notebook). However, because the
Windows display drivers cannot automatically
detect that the internal display is ON, you must
open the System object, select the Screen page,
change to a lower resolution, and then shut down
and restart your system if you want to use a
WIN-OS/2 window or full-screen session. (If you
do not need to use a WIN-OS/2 session, you do not
need to make the change to the resolution in the
Settings notebook. When the laptop is
reconnected to an external display, the
originally chosen resolution will be used again.)
When using your laptop away from the office, the
System Settings notebook will most likely show
resolutions which are not possible to use on the
internal display. On some laptops, all
resolutions appear in the System Settings
notebook, regardless of which displays were on
when the OS/2 display driver was installed. On
most laptops, the higher resolutions appear in
the System Settings notebook only if the OS/2
Page 17
display driver was installed while the internal
display was OFF. To add higher resolutions to
the System Settings notebook, do the following:
1. Shut down and restart your computer with the
internal display OFF.
2. Open an OS/2 or DOS full screen.
3. Type the following and press Enter:
SVGA ON
4. Open the Settings notebook for the System
object and select a higher resolution from
the Screen page.
5. Shut down and restart your computer.
o An external display attached to your system can
use resolutions above 640x480 while an internal
display cannot. Whenever you switch to an
internal display, you should change the
resolution to 640x480x256. To change the
resolution, do the following:
1. Open OS/2 System.
2. Open System Setup.
3. Open System.
4. On the Screen page of the notebook, select
640x480x256.
5. Close the notebook.
6. Shut down and restart your computer.
Page 18
NOTE: If you do not follow the above steps, the
Desktop will automatically switch to the
640x480x256 resolution because the
internal display cannot handle the higher
resolutions. However, Windows
applications running in a WIN-OS/2 window
or full-screen session will have problems
because the WIN-OS/2 session settings
cannot automatically update from a higher
resolution to the 640x480x256 resolution.
The OS/2 Desktop will be functional enough
to correct this situation by using the
above steps. These steps can be done
using either the internal or external
display.
o Due to a hardware restriction, MODE 132 will not
work on the internal display.
o MODE 40 on an external display will utilize only
half of the screen.
o If your system comes up with a black screen,
toggle the Fn+F5 keys to correct the problem. If
you have an external keyboard attached to your
system, refer to the documentation that came with
your computer for information about the internal
or external display function key.
o If you are using an external display, you might
occasionally encounter a band (usually black)
Page 19
across the screen when you start the system. To
correct this problem, do the following:
1. Perform a shutdown of your system.
2. Turn your computer off and then on again.
SETTING YOUR DISPLAY TO VGA MODE
________________________________
Use the following procedures to return to VGA mode.
NOTE: If your display is out of sync, start OS/2
using the OS/2 Installation Diskette, insert
Diskette 1 when prompted, then press F3 to
display a command prompt. Use the following
instructions to reset your display mode:
o If you are installing this driver on OS/2 Warp,
returning to VGA mode has been simplified. Do
the following:
1. Turn on your computer. If your computer is
already on, press Ctrl+Alt+Del to restart it.
2. When a small white box appears in the upper
left-hand corner of your screen, press
Alt+F1.
3. When the Recovery Choices screen appears,
press V.
Page 20
Your display adapter is restored and can work in
VGA mode. If you want to install a new display
adapter or video device driver, refer to Chapter
16, "Video Procedures," in the User's Guide to
OS/2 Warp.
o If you are installing this driver on OS/2 2.1,
2.11, or OS/2 for Windows, and you installed from
diskettes, do the following:
1. Be sure RSPDSPI.EXE is in the \OS2\INSTALL
directory. If it is, go to step 2. If it is
not, insert Diskette 8 into drive A and
unpack RSPDSPI.EXE with the following
command:
C:\OS2\UNPACK A:\INSTAID C: /N:RSPDSPI.EXE
(where A: is the drive containing Diskette 8,
and C: is the drive where OS/2 is installed.)
2. Type C: and then press Enter.
3. Type CD C:\OS2\INSTALL and then press Enter.
4. Type the following:
RSPDSPI /PK:VGA /SK:NONE /S:A:\ /T:C:
Page 21
(In /T:C:, C: is the drive where OS/2 is
installed. In /S:A:, A: is the diskette
drive you use to install OS/2.)
Then press Enter.
o If you are installing this driver on OS/2 2.1,
2.11, or OS/2 for Windows, and you installed from
CD-ROM or a LAN, do the following:
1. Be sure RSPDSPI.EXE is in the \OS2\INSTALL
directory. If it is, go to step 2. If it is
not, unpack RSPDSPI.EXE with the following
command:
C:\OS2\UNPACK E:\DISK_8\INSTAID C: /N:RSPDSPI.EXE
(where C: is the drive where OS/2 is
installed, and E: is the CD-ROM or LAN
drive.)
2. Type C: and then press Enter.
3. Type CD C:\OS2\INSTALL and then press Enter.
4. Type the following:
RSPDSPI /PK:VGA /SK:NONE /S:E:\OS2SE21\ /T:C:
Page 22
(In /T:C:, C: is the drive where OS/2 is
installed. In /S:E:, E: is the CD-ROM or LAN
drive.)
Then press Enter.
