A05 'HOO ® 2SWL3OH[ ® *;DQG1; 'RFXPHQWDWLRQ8SGDWH This document updates information contained in your Dell OptiPlex GX1 and NX1 system documentation. It describes the following features: Reinstallation of DirectX and video drivers Proper configuration of network drivers if you have a 3Com® PCI 3C905b Ethernet network interface controller (NIC) Reinstallation of the Microsoft® -updated Advanced Technology Attachment Packet Interface (ATAPI) driver for the Microsoft Windows NT ® 4.0 operating system New online documentation New System Setup options System board layout for new OptiPlex systems New microprocessor option 5HLQVWDOOLQJ'LUHFW;DQG9LGHR'ULYHUV If you ever need to reinstall the Microsoft Windows® 95 operating system, you should also reinstall the software drivers and utilities that came with your Dell system. This section specifically describes how to reinstall DirectX drivers and video drivers. Your online System User's Guide or Network Administrator's Guide describes how to install other types of drivers and utilities. DirectX is a group of technologies designed to enhance application programs that are rich in multimedia elements such as full-color graphics, video, 3D animation, and surround sound. The presence of DirectX drivers on your system also ensures accelerated-graphics port (AGP) support. To reinstall DirectX drivers and any other drivers and utilities that came with your system, you need a set of diskettes that contain the software. If your computer is not part of a centrally managed network, such as a network that connects computer workstations in an office environment, you should create a set of program diskettes using the Dell Program Diskette Maker. The program diskettes contain installation programs for the drivers and utilities needed by your system. To access the Program Dell OptiPlex GX1 and NX1 Documentation Update 1-1 Diskette Maker, click the Start button and point to Programs. Then point to Dell Accessories and click Program Diskette Maker. If your computer is part of a centrally managed network, check with your network administrator for information on reinstalling drivers and utilities. If you are a network administrator and you received the Network Administrator's Kit, Dell provides drivers and utilities for Windows 95 on diskettes. Normally, you should install the drivers on the managing server and then use Intel® LANDesk® Configuration Manager to download and install the drivers on an OptiPlex GX1 Managed PC system or an OptiPlex NX1 Net PC system. See your online Network Administrator's Guide for information on downloading and installing drivers over the network. To reinstall DirectX drivers locally on a system with a diskette drive, follow these steps: 1. If you have not done so already, create a program diskette set of drivers as described previously. Or, if you received the Network Administrator's Kit, locate the diskettes containing drivers and utilities. If you reinstalled Windows 95, make sure Universal Serial Bus (USB) support was reinstalled along with the operating system. USB support is enabled when Windows 95 is installed by Dell. However, if you need to reinstall the operating system, USB support should also be reinstalled. See your system's Reference and Installation Guide or your online Network Administrator's Guide for more information. 3. 4. 5. 6. 7. Save any work and close all application programs, because you will need to restart the computer at the end of this procedure to complete the installation. Insert the DX5 Drivers Diskette 1 into the diskette drive. Click the Start button and then click Run. Type a:\setup.exe and click OK. Follow the instructions on your screen, and insert the DX5 Drivers Diskette 2 when prompted. When the setup.exe program is complete, a message appears prompting you to run another program. 8. 9. Click the Start button and then click Run. Type c:\windows\ dx5core.exe and click OK. Follow the instructions on your screen to complete the DirectX drivers installation and restart the system when prompted. 2. 10. After the system restarts, insert the video drivers diskette into the diskette drive. 11. Click the Start button and then click Run. 12. Type a:\setup.exe and click OK. 1-2 Dell OptiPlex GX1 and NX1 Documentation Update 13. Follow the instructions on your screen to reinstall the primary video drivers. When Windows 95 restarts, you can change the display resolution and color depth. See the operating system documentation for more information. NOTE: If you change the display resolution, you may need to adjust the refresh rate for optimum viewing. &RQILJXULQJD&RP3&,&E1,& The following subsections describe how to manually set the network frame type for an Internetwork Packet Exchange/Sequenced Packet Exchange (IPX/SPX)-compatible network protocol and which version of 3Com EtherDisk® XL drivers and utilities you should use. 6HWWLQJWKH1HWZRUN)UDPH7\SH If your system is connected to a network, verify the following network protocol settings: 1. 2. 3. 4. 5. 6.

If you purchased a 3Com 3C905-based NIC separately, do not attempt to use the 3Com EtherDisk XL diskettes that came with the NIC. Use only the 3Com EtherDisk XL version 3.01 diskettes that were provided by Dell. For more information on NIC drivers and utilities, see your system's Reference and Installation Guide or your online Network Administrator's Guide. 0LFURVRIW8SGDWHG$7$3,'ULYHU If you purchased Microsoft Windows NT 4.0 with your computer, your system is equipped with the Microsoft-updated ATAPI driver. Dell OptiPlex GX1 and NX1 Documentation Update 1-3 Dell has installed the Microsoft-updated ATAPI driver for your operating system, and it is operative when you receive your computer. No further installation or configuration is needed. NOTE: If Windows NT 4.0 is reinstalled, the Microsoft-updated ATAPI driver must also be reinstalled. The driver for Windows NT 4.0 has also been copied to your hard-disk drive in diskette-image form. If you need to reinstall or remove this driver, you can do so as described in the following subsections. 5HLQVWDOOLQJWKH:LQGRZV170LFURVRIW8SGDWHG $7$3,'ULYHU NOTE: To install the Microsoft-updated ATAPI driver for Windows NT 4.0, you must have a mouse connected to the system and Windows NT 4.0 must already be installed on the hard-disk drive connected to the primary enhanced integrated drive electronics (EIDE) channel. To reinstall the Microsoft-updated ATAPI driver for Windows NT 4.0, follow these steps: 1. If you have not already done so, use the Program Diskette Maker to make a diskette copy of the Dell Microsoft-updated ATAPI driver diskette image on your hard-disk drive. The Program Diskette Maker is available through the Dell Accessories program folder. For more information, refer to the online help provided in the Program Diskette Maker. 2. 3. 4. Start Windows NT. If you are already running Windows NT, close any open documents or application programs. Insert the Microsoft-updated ATAPI driver diskette into drive A. Click the Start button and click Run. Type a:\setup.bat in the Run window, and then click OK. A black screen quickly appears and disappears, indicating that the driver file has been loaded. Setup automatically saves the existing atapi.sys driver as atapi.000 and loads the new driver into the system32\drivers subdirectory in the Windows NT directory. 5. Remove the diskette from drive A. Then restart the system. NOTE: To enable or disable direct memory access (DMA) while using the Microsoftupdated ATAPI driver, run dmacheck.exe from \support\utils\i386 on the Microsoft Windows NT Service Pack 3 CD-ROM. 1-4 Dell OptiPlex GX1 and NX1 Documentation Update 5HPRYLQJWKH:LQGRZV170LFURVRIW8SGDWHG$7$3, 'ULYHU To remove the Microsoft-updated ATAPI driver, follow these steps: 1. 2. 3. 4. 5.
