INSTALLATION FROM DISKETTE
--------------------------
This video accelerator driver is compatible with OS/2 2.1.
Do not install it on previous versions of OS/2.
To install this miro video accelerator driver from diskette:
1. Place this 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:
A:S3INST A: C:
where: A: is the diskette drive
C: is the drive where OS/2 2.1 is installed
This command will copy all necessary files to the OS/2 drive.
4. Remove the diskette from the diskette drive, perform a shutdown, and
then restart the system.
5. Open the "OS/2 System" folder.
6. Open the "System Setup" folder.
7. Open the "Display Driver Install" (DSPINSTL) object.
When the Display Driver Install window appears, "S3" should be the
default choice. Select "OK".
8. When the source directory pop-up window appears, insert the S3
OS/2 display driver diskette and select Install.
DSPINSTL determines the hardware configuration by creating the
SVGADATA.PMI file on the drive where the OS2 directory is located.
If the SVGADATA.PMI file has not been created, the adapter will not
be supported.
9. When the installation is complete, do the following:
a. Open "OS/2 System".
b. Open "System Setup".
c. Open the "System" object. The Screen page of the Settings
notebook lists all the supported resolutions for your
configuration.
d. Select a resolution; then, close the notebook.
10. Open a DOS box full screen session and start
<Bootdrive>:\os2\wininst\install <Bootdrive>:
11. Follow the Win/OS2 install procedure.
12. Close the Win/OS2 session.
13. Perform a shutdown; then, restart the system.
Note that during the installation of this driver a DISPLAY.LOG file is
created in the OS2\INSTALL directory. This file identifies the OS/2 2.1
system files that were updated and indicates whether the installation
was successful.
