- 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.
-
-
-
- 5.0 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 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 device driver using CID,
- use the following information to modify your LCU
- command file.

-
- 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.
- 2. After the WD90C24 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.
- 3. After the CID install, refer the end user to
- 4.0 INSTALLATION FROM DISKETTE step 11.
-
-
- 6.0 FUNCTIONAL RESTRICTIONS
- _______________________
-
- o The WD90C24 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,
- OS/2 2.1 users of the feature will experience unusual
- results. An OS/2 pervasive fix package is
- available electronically (request fix package XR06200).
- The associated APAR PJ11051 is fixed in 2.11 and above.
- The software motion feature is not supported in
- 16 million color modes.
- o Distributed Console Access Facility* (DCAF) is
- supported in 256-color modes only.
- 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.
-
-
- 6.1 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.
- 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
- display driver was installed while the internal
- display was OFF.
- 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 while the external
- display is attached. 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.
-
- 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 MODE 132 does not work.
- o MODE 40 on an external display will utilize only
- half of the screen.
- o If your system comes up with a black screen while
- the external display is attached, press the
- display toggle 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)
- 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.
- o On the ThinkPad 755CSE: There is a noticable
- "moving ripple" effect, especially in the gray areas
- of inactive title bars. This can be circumvented
- by using different color schemes. In some cases,
- running Lockup once clears up the problem.
-
- 7.0 SETTING YOUR DISPLAY TO VGA MODE
- ________________________________
-
- Use the following procedures to return to VGA mode.
-
- o If you are installing this driver on OS/2 Warp,
- and you do not have a usable OS/2 Desktop, use
- the following procedures to return to VGA mode.
- However, if you have a usable Desktop, it is
- recommended that you use Selective Install to set
- your display to VGA mode.
-
