- COMPATIBILITY STATEMENT
- -----------------------
-
- This WD90C24 Device Driver has been tested for compatibility with Toshiba
- Models: T4700CT and T4700CS.
-
- FEATURES
- ---------
-
- This WD90C24 Device Driver provides seamless support for accelerated graphics
- when used with the minimum required video memory. It conforms to the OS/2 2.1
- 32-bit flat memory model and is designed to function as a 32-bit Presentation
- Manager* display driver under the OS/2 2.1 32-bit graphics engine.
-
- The WD90C24 Device Driver supports these resolutions and color depths:
-
- Resolutions Number of Video Memory Display
- Colors Required
- 640 x 480 256 1MB Internal/External
- 800 x 600 256 1MB External
- 1024 x 768 256 1MB External
-
- It supports the following number of columns and rows in an OS/2 full-screen
- session:
-
- Columns Rows
- 132 25
- 132 43
-
-
- EXTERNAL AND INTERNAL DISPLAYS
- ------------------------------
-
- 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:
-
- 1. Open "OS/2 System".
- 2. Open "System Setup".
- 3. Open "System".
- 4. Select 640x480x256.
- 5. Close the notebook.
- 6. Shutdown; then restart the system to activate the change.
-
- 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.
-
-
- FUNCTIONAL RESTRICTIONS
- -----------------------
-
- 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 the screen.
-
- 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.
-
- o If your system comes up with a black screen, toggle the Fn+F5 key to
- correct the problem. If you have an external keyboard attached to the
- system, refer to the system's reference book 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) across the screen when you startup the system.
- To correct this problem:
-
- 1. Perform a Shutdown.
- 2. Power the system off then on again.

- INSTALLATION FROM DISKETTE
- --------------------------
-
- NOTES:
- 1. The SETUP program creates a directory called C:\ARCHIVE on the
- target drive (assuming the target drive is C). This directory will
- contain backups of the files installed on the target drive. If you
- want to change the name of the directory, edit the RESPONSE.FIL file
- on the diskette and change the :ARCHIVE C:\ARCHIVE line to reflect
- the changes.
-
- 2. The SETUP program installs this video device driver to the C drive.
- If you want to install to a target drive other than C, edit
- the RESPONSE.FIL file on the source drive and change the :TARGET C:\
- line in the file to reflect the new target drive and directory.
-
