1) Installation
===============
NOTE: If you are upgrading from the 4.03.00.2101-0071 Release Candidate 2
then you will be warned that three files have a for a different language.
This was a bug in RC2 and you should reply NO when asked if you want to
keep the old file in all three cases, so that Windows 95 DOES install the
files from the final release.
1.1 Download into an appropriate scratch directory
(e.g. C:\3dlabs).
1.2 Use pkUnzip to uncompress the .ZIP file USING THE
-d OPTION to preserve the directory structure...
> pkUnzip -d c:\3dlabs\XXXX.ZIP
1.3 This will produce a .PDF file, which contains the release notes for the
Display Driver and OpenGL driver, and the driver files. The PDF file may
viewed using the Adobe Acrobat viewer available from http://www.adobe.com.
1.4 Use this directory as the "Have Disk" target to install the new
driver using the control panel display applet in the normal way.
Full installation instructions can be found in the .DOC file.
1.5 You can now delete the download scratch directory and its contents.
