Installing the Prerelease Version of the Tseng ET4000W32 Display Adapter Device Driver for NEXTSTEP Release 3.2 for Intel Processors
These instructions show you how to install the prerelease version of the Tseng ET4000W32 display adapter device driver on an Intel-based computer running NEXTSTEP(TM) Release 3.2. The driver is distributed in an Installer package file named TsengET4000W32DisplayDriver.pkg.
This new graphics driver supports display adapters based on the Tseng ET4000W32 graphics controller chipset, including the NEC Image systems with on-board display adapters with 2MB DRAM and the Lightspeed VL adapter by STB Systems with 2MB DRAM.
Caution: The ET4000W32i driver doesn't work with SoftPC full-screen mode if there are only 1MB video DRAM on the NEC Image systems.
Caution: 1024x768 16-bit non-interlaced modes are not supported by ET4000W32p chip on the NEC Image systems. 1024x768 16-bit interlaced mode is supported.
Note: The Lightspeed VL card useds ET4000W32p chip, and thus also supports 1024x768 16-bit non-interlaced mode.
Warning: Some vendors claim that you can use their display adapters 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 very high frequency 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 TsengET4000W32DisplayDriver.pkg file via NeXTmail(TM) 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 TsengET4000W32DisplayDriver.pkg file on a floppy disk, insert the disk in the floppy disk drive and choose Check for Disks from the Workspace Manager(TM) 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 TsengET4000W32DisplayDriver.pkg package. Otherwise the drivers you add may not appear in Configure's Add Display Devices panel.
4. Double-click the TsengET4000W32DisplayDriver.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 Tseng ET4000W32 Display Adapter." If you plan to install the STB Lightspeed VL display adapter and if the existing adapter listed 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 STB Lighspeed VL display adapter, and then start up the computer and log in again as root.
Configuring the Tseng ET4000W32 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. Caution: Because of a known bug in Configure, at this point you have to click save, ignore the warning that there is no display adapter chosen, quit, then restart Configure, and click the display icon. Now continue to step 4.
4. Click Add.
5. Select the Tseng ET4000W32 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. Then click OK. Note: Higher resolution modes may require higher resolution displays. Refer to the manual for your display to determine valid modes.
7. Choose Save from Configure's Configuration menu and then choose Quit.
Removing the Installer Package and Restarting the Computer
1. If you had created a copy of the TsengET4000W32DisplayDriver.pkg file in step 1, drag the copy to the recycler.
2. 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.
