- 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.
-
