-
- 1. Introduction
- ---------------
-
- This document discusses the issues concerning CID installation of the
- MGA OS/2 Drivers.
-
- The OS/2 utility DSPINSTL.EXE is used to perform CID installation of
- display drivers.
-
- Typically, CID installation is done by running a batch file. The
- system administrator customizes the batch file and then runs it on the
- system to be upgraded. The batch file attaches the network drive that
- contains the MGA drivers to the local computer, and then runs
- dspinstl to install the drivers.
-
- A script file (MGAX64.DSP) is used to tell DSPINSTL where to install
- the various components of the MGA driver.
-
- The script file included with the MGA OS/2 Drivers disk will install
- the display driver. Once the drivers are installed, the user can
- configure the driver by launching the System Icon object, or by
- running the MGASET utility.
-
- If the system adminstrator wishes to configure the driver during CID
- installation (choose monitor type, resolution, pixel depth) then he/she
- will have to modify the script file (MGAX64.DSP).
-
- Where to go from here:
-
- -To install the driver via CID using the default driver
- configuration, go to section 3.
-
-
- -To install the driver via CID using a custom configuration,
- go to section 2.
-
-
-
- 2. Configuring the driver via CID
- ---------------------------------
-
- 2.1 Screen resolution and pixel depth:
-
- To configure the boot-up resolution and pixel depth of the driver,
- add the following lines to the MGAX64.DSP script file:
-
- :SET_RESOLUTION
- WIDTH=wwww
- HEIGHT=hhhh
- COLORS=cccc
- PLANES=1
-
- where wwww = display width
- hhhh = display height
- cccc = number of colours (256, 65536, or 16777216)
-
- Valid width/height combinations are: 640x480, 800x600, 1024x768,
- 1152x864, 1280x1024, 1600x1200, 1600x1280, and 1800x1440. Depending
- on the type of board installed, and on how much VRAM is available,
- not all resolutions are supported. If an invalid resolution is
- specified, then the driver will boot using the default 640x480
- resolution.
-
-
- 2.2 Monitor selection
-
- Monitor selection is necessary to tell the driver what resolutions
- and refresh rates are supported by the monitor.
-
- Certain monitors (DDC monitors) are able to communicate their
- capabilities to the display driver. When such monitors are being
- used, the monitor selection step is not required.
-
- When a non-DDC monitor is being used, the driver relies on the
- MGA.INF file to know the monitor capabilities. This file is generated
- by selecting a monitor using the MGASET utility. If no MGA.INF file
- exists (and the monitor is non-DDC), the driver will use the default
- 60 Hz refresh rate for all resolutions.
-
- Once the system administrator has generated an MGA.INF file, the
- MGAX64.DSP script can be modified to copy the MGA.INF file to the
- appropriate location on the system being upgraded. This line must be
- added to the :FILES section of MGAX64.DSP
-
- MGA.INF %BOOTDRIVE%:\MGA\OS2
-
- This line assumes that the MGA.INF file can be found in the same
- directory as the DSP script.
-
-
-
- 3. Installation of the MGA OS/2 Drivers via CID
- -----------------------------------------------
-
- Installation of the drivers via CID is done using OS/2's DSPINSTL
- utility. The INSTALL.CMD batch file included with the installation disk
- makes use of this utility.
-
- Before running INSTALL, the system being upgraded should be able to
- access the network directory containing the new drivers. Also, if the
- administrator has made modifications to the MGAX64.DSP script or to
- MGA.INF (as described in section 2), these files should be located in
- this network directory.
-
- From an OS/2 session, type:
-
- X:\DSKIMAGE\INSTALL X:\DSKIMAGE D: /U
-
- where X:\DSKIMAGE is the network driver and directory containing the
- new drivers.
-
- D: is driver where the drivers are to be installed.
