Installing ATI PCI Display Adapter Device Driver for NEXTSTEP Release 3.2 for Intel Processors

These instructions show you which computer systems are supported by the PCI ATI display adapter device driver. They also show you how to install the device driver on an Intel-based computer running NEXTSTEPä Release 3.2. The driver is distributed in an Installer package file named ATI_PCI.pkg.

Supported ATI Display Adapters

PCI ATI display adapter device driver supports only ATI PCI bus on-board display adapter at the following display modes.

Supported Computer Systems

PCI ATI display adapter device driver lets you take advantage of the PCI systems with on-board ATI-based display adapter.

Matching Display Modes with Your Display

Before selecting display modes with higher resolutions or refresh rates, refer to your display's owner's guide to verify that it can synchronize with the signal from your display adapter.

For example, some displays can't synchronize with the 1280 x 1024 noninterlaced 60 Hz signal produced by the highest resolution grayscale display mode. In addition, many "generic" SVGA displays can't synchronize with 800 x 600 noninterlaced signals at refresh rates above 60 Hz.

Installing the Device Driver

1.	If you received the ATI_PCI.pkg file via NeXTmailä or another electronic source, place a copy of the file in a location where you can access it when you log in as root.

2.	Log in as root.
	Only the superuser, root, can install the updated device driver. If you're not sure how to log in as root, see your system administrator.

3.	If you received the ATI_PCI.pkg file on a floppy disk, insert the disk in the floppy disk drive and choose Check for Disks from the Workspace Managerä application's Disk menu. When the disk icon appears in the File Viewer, double-click it to open it.

4.	Double-click the ATI_PCI.pkg file.

5.	Click the Install button in the Installer package window. When the panel asks you to confirm that you want to install the package, click Install. Then click Continue in the panel that warns you you're about to overwrite existing files. 

6.	After copying all files start up the Configure.app in /NextAdmin directory.

7.	Click the Video icon at the top of Configure's Summary window, choose PCI ATI display adapter and then click Select in the Display Mode area of the Video Devices view. 
	
8.	In the Select Display Mode panel, select the resolution with the highest refresh rate your display adapter or system and display can support. Then click OK.
Note: Be careful not to select a resolution or refresh rate that you monitor is not capable of supporting. This could cause cause unpredictable results to the monitor. 

9.	Choose Save from Configure's Configuration menu and then choose Quit.

10.	When the installation is complete, choose Quit from the Installer menu.

11.	If you created a copy of the ATI_PCI.pkg file in step 1, drag the copy to the recycler. 

12.	Choose Log Out from the Workspace menu and then click the Restart button in the Login window.

	You must restart your computer after installing and configuring the updated device driver.

The next time you start up your computer, it will use the new driver to display NEXTSTEP in the display mode you selected in Configure.

Note: If you notice a fuzzy or "sparkling" appearance after you restart the computer, use the Configure application to change your Display Mode to a different resolution, a lower refresh rate, or both.

For information about the logging in and out, the Workspace Manager application, and the Installer application, see the NEXTSTEP User's Guide. For information about the Configure application, see Installing and Configuring NEXTSTEP Release 3.2 for Intel Processors.
