Installing Update 1.1 of the QVision Device Driver for NEXTSTEP Release 3.2 for Intel Processors

These instructions show you how to install theQVision display adapter device driver on an Intel-based computer running NEXTSTEPä Release 3.2. The driver is distributed in an Installer package file named QVisionDriver.pkg. 

The QVision device driver supports the new LocalBus QVision Graphics Controllers included on the Compaq Deskpro XE Series. The new XE Series support 1 megabyte or 2 megabyte size video frame buffers. This driver is designed to continue to support the existing QVision EISA adapters supported by the driver included with NEXTSTEP 3.2 for Intel Processors.

This device driver supports the QVision display adapter in the following display modes.

Warning: Some vendors claim that you can use their display adpaters at display modes with resolutions and refresh rates that exceed what their RAMDACs can support. You can permanently damage your display adapter and computer by doing this. Read the owner's guide that comes with your display adapter or contact its manufacturer to ensure that your adapter's RAMDAC can support the display mode you set in Configure.

Supported Displays

NeXT designs and tests its display adapter device drivers using displays that can support display modes with very high resolutions and non-interlaced refresh rates, such as the NEC 5FG, NEC 6FG, and Nokia Multigraph  445X. Read the owner's guide that comes with your display to ensure it can support the display mode you set in Configure.

Installing the Device Driver

1.	If you received the QVisionDriver.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 device driver. If you're not sure how to log in as root, see your system administrator.
3.	If you received the QVisionDriver.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. 
Note: Make sure Configure isn't running while you install the QVisionDriver.pkg package. Otherwise the drivers you add may not appear in Configure's Add Display Devices panel. 
4.	Double-click the QVisionDriver.pkg file.
5.	Click the Install button in the Installer package window. When the panel asks you to confirm that you want to install software for Intel-based computers, click Install. 
6.	When the installation is complete, choose Quit from the Installer menu.
7.	Start up the Configure application by double-clicking Configure.app (it's in /NextAdmin).  
8. 	Click the Display icon at the top of Configure's Summary window. Your current adapter appears in the list at the top of Configure's Display Devices window. If the current adapter is the Default VGA Adapter, then skip the next section and continue following steps in the section "Configuring the QVision Display Adapter." If the existing adapter is anything other than Default VGA, then continue by following the steps in the next section "Replacing an Existing Display Adapter." 

Replacing an Existing Display Adapter 

1.	Click the Display icon at the top of Configure's Summary window. The current adapter appears as the only name in the list at the top of Configure's Display Devices window. 
2.	Select the current adapter in the list and click Remove. 
3. 	Click Add. 
4.	In the Add Display Devices panel, click Default VGA Adapter and click Add. 
5. 	Choose Save from Configure's Configuration menu and choose Quit. 
6. 	Log out, turn off your computer, replace the existing display adapter with the QVision adapter, and then start up the computer and log in again as root. 

Configuring the QVision Display Adapter

1.	If it's not already running, start up the Configure application.  
2. 	Click the Display icon at the top of Configure's Summary window. The current adapter name should be Default VGA Adapter. 
3. 	Select the Default VGA Adapter and click Remove. 
4. 	Click Add.  
5. 	Select the QVision display adapter in the Add Display Devices panel. Then click Add.
6.	Click Select in the Display Mode area of the Display Devices window, and in the Select Display Mode panel, select the combination of color, resolution, and refresh rate appropriate for your adapter and display (for details, see the charts earlier in this document). Then click OK. 
7.	Choose Save from Configure's Configuration menu and then choose Quit.
8.	If you had created a copy of the QVisionDriver.pkg file in step 1, drag the copy to the recycler. 
9.	Choose Log Out from the Workspace menu and then click the Restart button in the Login window.
Note: You must restart your computer after installing and configuring the 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.
