your Diagnostics and Troubleshooting Guide. ‡ Do not push any objects into the openings of your computer. Doing so can cause fire or electric shock by shorting out interior components. ‡ Keep your computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loose papers underneath your computer; do not place your computer in a closed-in wall unit or on a bed, sofa, or rug. (UJRQRPLF&RPSXWLQJ+DELWV :$51,1*,PSURSHURUSURORQJHGNH\ERDUGXVHPD\UHVXOWLQLQMXU\ For comfort and efficiency, observe the following ergonomic guidelines when setting up and using your computer system: ‡ Position your system so that the monitor and keyboard are directly in front of you as you work. Special shelves are available (from Dell and other sources) to help you correctly position your keyboard. ‡ Set the monitor at a comfortable viewing distance (usually 510 to 610 millimeters [20 to 24 inches] from your eyes). ‡ Make sure the monitor screen is at eye level or slightly lower when you are sitting in front of the monitor. ‡ Adjust the tilt of the monitor, its contrast and brightness settings, and the lighting around you (such as overhead lights, desk lamps, and the curtains or blinds on nearby windows) to minimize reflections and glare on the monitor screen. ‡ Use a chair that provides good lower back support. ‡ Keep your forearms horizontal with your wrists in a neutral, comfortable position while using the keyboard or mouse. ‡ Always leave space to rest your hands while using the keyboard or mouse. ‡ Let your upper arms hang naturally at your sides. ‡ Sit erect, with your feet resting on the floor and your thighs level. ‡ When sitting, make sure the weight of your legs is on your feet and not on the front of your chair seat. Adjust your chair’s height or use a footrest, if necessary, to maintain proper posture. ‡ Vary your work activities. Try to organize your work so that you do not have to type for extended periods of time. When you stop typing, try to do things that use both hands.

In addition, take note of these safety guidelines when appropriate: ‡ When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs; if you are dis- connecting this type of cable, press in on the locking tabs before disconnecting the cable. As you pull connectors apart, keep them evenly aligned to avoid bend- ing any connector pins. Also, before you connect a cable, make sure both connectors are correctly oriented and aligned. ‡ Handle components and cards with care. Don’t touch the components or con- tacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a microprocessor chip by its edges, not by its pins. %DWWHU\:DUQLQJ 3URWHFWLQJ$JDLQVW(OHFWURVWDWLF'LVFKDUJH Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computer’s electronic components, such as the microprocessor. You can do so by touching an unpainted metal surface on the computer chassis. As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have accumulated. You can also take the following steps to prevent damage from electrostatic discharge (ESD): ‡ When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are ready to install the component in your computer. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body. ‡ When transporting a sensitive component, first place it in an antistatic container or packaging. ‡ Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads. :$51,1* 7KHUHLVDGDQJHURIDQHZEDWWHU\H[SORGLQJLILWLVLQFRUUHFWO\LQVWDOOHG 5HSODFHWKHEDWWHU\RQO\ZLWKWKHVDPHRUHTXLYDOHQWW\SHUHFRPPHQGHG E\WKHPDQXIDFWXUHU'LVFDUGXVHGEDWWHULHVDFFRUGLQJWRWKHPDQXIDF WXUHU·VLQVWUXFWLRQV

,QWURGXFWLRQ Dell® OptiPlex® GX1 and GX1p mini tower Managed PC systems are high-speed, expandable personal computers designed around the Intel® Pentium® II microproces- sor. Each computer system uses a high-performance Peripheral Component Interconnect (PCI) design that allows you to configure the computer system to your initial requirements and then add Dell-supported upgrades as necessary. These sys- tems also support the Industry-Standard Architecture (ISA) bus for older expansion devices. This chapter describes the major hardware and software features of your system, pro- vides information about accessing the online documentation, and tells you where to find help if you need it. 6\VWHP)HDWXUHV Your system offers the following features: ‡ An Intel Pentium II microprocessor that runs at one of the following speeds: — An internal speed of 266 or 333 megahertz (MHz) and an external speed of 66 MHz — An internal speed of 350, 400, or 450 MHz and an external speed of 100 MHz The Intel Pentium II microprocessor includes MMX™ technology designed to handle complex multimedia and communications software. This microprocessor incorporates new instructions and data types as well as a technique called single instruction, multiple data (SIMD) that allows the microprocessor to process multi- ple data elements in parallel, thereby improving overall system performance. The Pentium II microprocessor has a 16-kilobyte (KB) internal data cache and a 16-KB internal instruction cache, an internal math coprocessor, and other advanced internal logic. ‡ A keyboard command (<\>) that lets you switch between the micro- processor’s rated speed and a slower compatibility speed. NOTE: This keyboard command is not available under the Microsoft® Windows NT ® and IBM ®OS/2®operating systems.

‡ A secondary cache of 512 KB of static random-access memory (SRAM) included within the single-edge contact (SEC) cartridge, which also contains the microprocessor. ‡ System memory that can be increased up to 384 megabytes (MB) by installing 64- or 128-MB synchronous dynamic random-access memory (SDRAM) dual in- line memory modules (DIMMs) in the three DIMM sockets on the system board. The system also supports both error checking and correction (ECC) and nonparity DIMMs. See “Adding Memory” in Chapter 6 for details. ‡ Self-Monitoring and Analysis Reporting Technology II (SMART II) support, which warns you at system start-up if your hard-disk drive has become unreliable. To take advantage of this technology, you must have a SMART II-compliant hard-disk drive in your computer. All hard-disk drives shipped with OptiPlex GX1 systems are SMART II-compliant. ‡ A basic input/output system (BIOS), which resides in flash memory and can be upgraded by diskette, or remotely over a network, if required. ‡ Full compliance with PCI specification 2.2. ‡ Full Plug and Play version 1.0a capability, which greatly simplifies the installation of expansion cards. Plug and Play support included in the system BIOS allows you to install Plug and Play expansion cards without setting jumpers or switches or performing other configuration tasks. The ISA Configuration Utility (ICU) allows you to configure existing non-Plug and Play ISA expansion cards for conflict-free operation. Also, because the system BIOS is stored in flash memory, it can be updated to support future enhancements to the Plug and Play standard. ‡ Wakeup On LAN capability, which, when enabled in the System Setup program, allows the system to be powered up from a server management console. Wakeup On LAN capability also allows remote computer setup, software down- loading and installation, file updates, and asset tracking after hours and on weekends when network traffic is at a minimum. For more information, refer to Chapter 2, “Using the System Setup Program.” ‡ Universal Serial Bus (USB) capability, which can simplify connecting peripheral devices such as mice, printers, and computer speakers. The USB connectors on your computer’s back panel, which are enabled by default, provide a single con- nection point for multiple USB-compliant devices. USB-compliant devices can also be connected and disconnected while the system is running. ‡ A modular computer chassis with a minimum number of screws for easy dis- assembly and improved serviceability. +DUGZDUH)HDWXUHV The system board includes the following built-in features: ‡ Three 32-bit PCI expansion slots, two shared PCI (32-bit)/ISA (16-bit) expansion slots, and two 16-bit ISA expansion slots on a riser board. ‡ A 64-bit accelerated graphics port (AGP) video subsystem, which includes the ATI 3D Rage Pro super video graphics array (SVGA) video controller. On the Dell Opti- Plex GX1, this video subsystem contains 4 MB (upgradable to 8 MB) of

OptiPlex GX1p comes with 8 MB of SGRAM video memory. Maximum resolu- tions are 1600 x 1200 with 65,536 colors noninterlaced and 1280 x 1024 and 1024 x 768 with true-colors noninterlaced. In 800 x 600 and 640 x 480 resolutions, 16.7 million colors are available for true-color graphics using a 32-bits per pixel (bpp) format. True-color provides higher performance, but uses more graphics memory. Table 1-1 lists the video memory requirements for the Microsoft Windows® 95, WIndows 98, and Windows NT 4.0 operating systems. 2X AGP provides a dedicated bus from the video subsystem to the system chip set. AGP-based video subsystems have two significant performance advantages over PCI-based video subsystems: — The AGP bus reduces bandwidth requirements of the PCI bus, improving overall system performance. — The AGP bus allows a 3D video subsystem to execute directly from main memory. ‡ A diskette/tape drive interface, which supports a 3.5-inch diskette drive and, optionally, a second diskette drive or tape drive. ‡ Enhanced integrated drive electronics (EIDE) support. The primary and secondary interface are both located on the PCI bus to provide faster data throughput. Each interface supports high-capacity EIDE drives, as well as devices such as ATA 33 hard-disk drives, EIDE CD-ROM drives, and EIDE tape drives. ‡ Two high-performance serial ports and one bidirectional parallel port for connect- ing external devices. The parallel port is fully Enhanced Capabilities Port (ECP)-compliant. ‡ A Personal System/2 (PS/2)-style keyboard port and a PS/2-compatible mouse port. 7DEOH9LGHR0HPRU\5HTXLUHPHQWV 9LGHR 5HVROXWLRQ 0D[LPXP &RORU'HSWK 0D[LPXP 5HIUHVK5DWH 0LQLPXP 6*5$05HTXLUHG 640 x 480 True-color (32 bpp) 85 Hz 4 MB 800 x 600 True-color (32 bpp) 85 Hz 4 MB 1024 x 768 True-color (32 bpp) 85 Hz 4 MB 1280 x 1024 True-color (32 bpp) 75 Hz 8 MB 1600 x 1200 65,536 colors (16 bpp) 75 Hz 8 MB

DMI defines the software, interfaces, and data files that enable your system to determine and report infor- mation about system components. If your system has a Dell-installed Microsoft Windows 95 operating system, DMI is already installed on your system’s hard-disk drive. To learn more about DMI, double-click the DMI icon in the Windows Control Panel. If your system included Dell-installed software, Dell provides a menu that allows you to make program diskette sets of your Dell-installed software (programs, drivers, and utilities; a CD-ROM with your operating system accompanied your computer). A program diskette set is an uninstalled version of a software package that you can use to reinstall or reconfigure the software. You can use this same menu to remove diskette image files (individual files that correspond to each dis- kette in a program diskette set) to reclaim space on the computer’s hard-disk drive. For more information on making program diskette sets, see the online help provided in the Dell Program Diskette Maker, which is located in the Dell Acces- sories folder. ‡ The Dell OpenManage™ program, which is a DMI browser that allows you to view your computer’s current hardware configuration and operating system ver- sion. The Dell Inspector provides information you may need if you call Dell for technical assistance or if you install hardware or software in your system. The Dell Inspector program is located in the Dell Accessories folder. For more infor- mation on the Dell Inspector program, see the next subsection, “Manageability Features.” 0DQDJHDELOLW\)HDWXUHV Your Dell OptiPlex GX1 or GX1p Managed PC system incorporates many hardware and software features to improve the manageability of the system.

ing off their computer systems when they are not in use for extended periods of time—particularly at night and on weekends. ,PSRUWDQW1RWHIRU:LQGRZV8VHUV Your system was configured by Dell to optimize the features of the Windows 95 oper- ating system. To ensure that all of these features are maintained on your system, you must use the version of Windows 95 that Dell installed on your hard-disk drive. Should you need to reinstall Windows 95 on an OptiPlex GX1 or GX1p system for any reason, you must be sure to reinstall the correct version. Dell recommends perform- ing a periodic tape backup of the system’s entire hard-disk drive so that, if necessary, the operating system, drivers, and other software can be reinstalled as originally con- figured with a minimum of downtime. If you are unable to reinstall your software from a tape backup of the hard-disk drive, you can reinstall Windows 95 from the system’s Windows 95 CD that you received from Dell. However, if you reinstall Windows 95 in this manner, the bus-mastering functionality of the Windows 95 EIDE driver, which was operative in your original con- figuration, will be disabled. (Your system will operate without the bus-mastering functionality with only a small degradation in performance. For information on the advantages of using bus-mastering drivers, see “Bus-Mastering EIDE Drivers” in the “Using Drivers and Utilities” section of your online System User’s Guide.) You may also need to reinstall your system’s video, audio, and NIC drivers from the diskettes created from the Dell-installed software on your system. NOTE: If you are a system administrator of corporate networks and you must down- load Windows 95 from a server to client systems, make sure that you have the Windows 95 backup media for the OptiPlex GX1 system on your server before downloading. ,QWHO3,,;,1)8SGDWH,QVWDOOHUIRU :LQGRZV NOTE: The following procedure applies only to versions of Windows 95 installed by Dell. If you must reinstall Windows 95 on your computer system, you also need to run the Intel PIIX4 INF Update Installer for Windows 95 immediately after installing the oper- ating system. Doing so enables Windows 95 to detect and configure PCI devices controlled by the integrated 82371EB component. Before you can perform the update, you must make a diskette copy of the update software from the disk image on the hard-disk drive. To make the diskette copy, use the Program Diskette Maker, which is located in the Dell Accessories folder. Refer to the online System User’s Guide for information about using the Program Diskette Maker.

If you prefer, you can type numbers in the month and day-of-month fields. 'LVNHWWH'ULYH$DQG'LVNHWWH'ULYH% Diskette Drive A and Diskette Drive B identify the type of diskette drives installed in your computer. With the standard cabling configuration, Diskette Drive A (the boot diskette drive) is the 3.5-inch diskette drive installed in the top externally accessible drive bay; Diskette Drive B is any drive installed in the bottom externally accessible drive bay that is connected to the system’s diskette/tape drive interface. The option settings always match the physical locations of the drives in your com- puter—the first drive listed on Page 1 of the System Setup screens is the top drive in your computer. The options are: ‡ 5.25 Inch, 360 KB ‡ 5.25 Inch, 1.2 MB ‡ 3.5 Inch, 720 KB ‡ 3.5 Inch, 1.44 MB ‡ Not Installed NOTE: Tape drives are not reflected in the Diskette Drive A and Diskette Drive B options. For example, if you have a single diskette drive and a tape drive attached to the diskette/tape drive interface cable, set the Diskette Drive A option to match the characteristics of the diskette drive and set the Diskette Drive B option to Not Installed. 'ULYHV3ULPDU\DQG6HFRQGDU\ Primary identifies drives attached to the primary enhanced integrated drive electron- ics (EIDE) interface connector (labeled “IDE1”) on the system board; Secondary identifies drives connected to the secondary EIDE interface connector (labeled

“IDE2”). It is recommended that you use the secondary EIDE interface connector for EIDE CD-ROM and EIDE tape drives. NOTES: For all devices from Dell that use the built-in EIDE controller, set the appropri- ate Drive option to Auto. For small computer system interface (SCSI) devices, set the appropriate Drive option to None. You must have an EIDE device connected to the primary EIDE interface if you have an EIDE device connected to the secondary EIDE interface. For older EIDE hard-disk drives not shipped with the system from Dell and less than 528 megabytes (MB) in capacity, you can use one of the following options if the Auto- detect feature does not work: ‡ A specific drive-type number ‡ Usr1 or Usr2 For each drive, seven parameters can be chosen as a group by drive-type number or entered individually from the keyboard. A drive-type number specifies the parameters of a hard-disk drive, based on a table recorded in the system’s BIOS. NOTE: Operating systems that bypass the system BIOS may not obtain optimum hard-disk drive performance. If you choose the Usr1 or Usr2 option, you must supply the following parameters for the drive: ‡ Type is the drive-type number for the selected hard-disk drive (in this case, Usr1 or Usr2). ‡ Cyls is the number of logical cylinders. ‡ Hds indicates the number of logical heads in the drive. ‡ Pre (precompensation cylinder) is the cylinder number at which the electrical cur- rent for the drive head changes to compensate for differences in data density across the disk surface (this parameter has no effect for EIDE drives). ‡ Lz is the cylinder number that is used as the drive’s landing zone for the heads when the drive is not in use. ‡ Sec is the number of logical sectors per track. ‡ Size (automatically calculated by the system) indicates the number of millions of bytes of storage provided by the drive. 5HVHUYHG0HPRU\ Reserved Memory allows you to designate a region of system board memory that can be supplied by an expansion card. You should not enable the reserved memory feature unless you are using an expansion card that requires special addressing. For example, you may have a memory expansion card that needs to be addressed starting at 15 MB. Selecting the 15M - 16M option in the Reserved Memory option specifies that the base memory from 15 to 16 MB come from the memory expansion

2-7 card (the base memory below the 15-MB address comes from the dual in-line mem- ory modules [DIMMs] on the system board). The Reserved Memory option has the following options: ‡ None (the default option) ‡ 512K - 640K ‡ 15M - 16M &386SHHG CPU Speed indicates the processor speed at which your system boots. Press the left- or right-arrow key to toggle the CPU Speed option between the resi- dent microprocessor’s rated speed (the default) and a lower compatibility speed, which lets you accommodate speed-sensitive application programs. A change to this option takes effect immediately (rebooting the system is not required). You can also toggle between the rated processor speed and the compatibility speed while the system is running in real mode by pressing <\>. (For keyboards that do not use American English, press <#>.) 1XP/RFN Num Lock determines whether your system boots with the Num Lock mode activated on 101- or 102-key keyboards (it does not apply to 84-key keyboards). When Num Lock mode is activated, the rightmost bank of keys on your keyboard provides the mathematical and numeric functions shown at the tops of the keys. When Num Lock mode is turned off, these keys provide cursor-control functions according to the label on the bottom of each key. &KDVVLV,QWUXVLRQ Chassis Intrusion displays the status of the system chassis intrusion monitor. The default setting is Not Detected. If the computer cover is removed, the setting changes from Not Detected to Detected and the following message is displayed during the boot sequence at system start-up: Alert! Cover was previously removed. To clear this field and allow future intrusions to be detected, enter the System Setup program during the system’s power-on self-test (POST), as described earlier in this chapter. At the Chassis Intrusion option, use the left- or right-arrow key to choose Reset. This action changes the setting to its default value, Not Detected. NOTE: When enabled, the setup password is required to reset the Chassis Intrusion option from Detected to Not Detected.

'$&6QRRS DAC Snoop lets you correct video problems that may occur when certain video add-in cards are used. The default is Off. If you are using a video add-in card and problems such as incorrect colors or blank windows occur, set DAC Snoop to On. $&3, This option controls the operation of the system’s Advanced Configuration and Power Interface (ACPI) feature. When ACPI is set to On, momentarily pressing the power button places the system in a power-saving mode. To turn the system off completely, press the power button for more than four seconds. When ACPI is set to On, interrupt request (IRQ) line 9 is not available for use by an expansion card. When ACPI is set to Off, momentarily pressing the power button turns off the system completely. With this setting, IRQ9 is available for use by an expansion card. .H\ERDUG(UURUV Keyboard Errors enables or disables reporting of keyboard errors during the POST, which is a series of tests that the system performs on the hardware each time you turn on the system or press the reset button. This option is useful when applied to self-starting servers or host systems that have no permanently attached keyboard. In these situations, selecting Do Not Report sup- presses all error messages relating to the keyboard or to the keyboard controller during POST. This option does not affect the operation of the keyboard itself if a keyboard is attached to the computer. 6\VWHP3DVVZRUG System Password displays the current status of your system’s password security fea- ture and allows you to assign and verify a new password. No one can assign a new password unless the current status is Not Enabled, which is displayed in bright characters. The settings for the System Password option are: ‡ Not Enabled (the default option) ‡ Enabled ‡ Disabled by Jumper NOTE: Read “Using the System Password Feature” found later in this chapter for instructions on assigning a system password and using or changing an existing system password. See “Disabling a Forgotten Password” found later in this chapter for instructions on disabling a forgotten system password.

2-9 3DVVZRUG6WDWXV When Setup Password is set to Enabled, Password Status allows you to prevent the system password from being changed or disabled at system start-up. To lock the system password, you must first assign a setup password in the Setup Password option and then change the Password Status option to Locked. In this state, the system password cannot be changed through the System Password option and cannot be disabled at system start-up by pressing . To unlock the system password, you must enter the setup password in the Setup Password option and then change the Password Status option to Unlocked. In this state, the system password can be disabled at system start-up by pressing and then changed through the System Password option. %RRW6HTXHQFH Boot Sequence can be set to Diskette First (the default option), Hard Disk Only, CD-ROM First, or Device List. The term boot refers to the system’s start-up procedure. When turned on, the system “bootstraps” itself into an operational state by loading into memory a small program, which in turn loads the necessary operating system. Boot Sequence tells the system where to look for the files that it needs to load. 'LVNHWWH)LUVW Selecting Diskette First causes the system to try booting from drive A first. If the system finds a diskette that is not bootable in the drive or finds a problem with the drive itself, it displays an error message. If it does not find a diskette in the drive, the system tries to boot from the hard-disk drive (drive 0), then from the CD-ROM drive, and finally from the Plug and Play network adapters in the order found. +DUG'LVN2QO\ Selecting Hard Disk Only causes the system to attempt to boot first from the hard- disk drive and then from the Plug and Play network adapters in the order found. &'520)LUVW Selecting CD-ROM First causes the system to try booting from the CD-ROM drive first. If the system finds a CD that is not bootable in the drive or finds a problem with the drive itself, it displays an error message. If it does not find a CD in the drive, the system tries to boot from drive A, then from drive C, and finally from the Plug and Play network adapters in the order found. 'HYLFH/LVW Device List provides access to the Device List screen where you can choose from a list of available boot devices to boot from and specify the order in which your computer

attempts to boot from these devices. To view the Device List screen, press and the right-arrow key.

2-11 NOTE: Non-Plug and Play devices appear in this list as Adapters without ID support. When determining the order of devices to boot from, the system first considers the order of the devices listed under the Device Controller Priority option, then the order of devices under Boot Device Priority. To specify your priority preferences, order the devices under these options so that the highest-priority controller is at the top of the Device Controller Priority option and the highest-priority device is at the top of the Boot Device Priority option. Order the remainder of the devices in the Boot Device Priority option according to your prefer- ences. Move any devices that you want the system to ignore during system start-up into the Exclude From Boot Device Priority option. NOTE: The system defines drive C in the Boot Device Priority option as the first hard- disk drive attached to the highest-priority device controller. Therefore, if you have a SCSI adapter installed in your computer and you want the SCSI drive 0 to be drive C, you must move the SCSI adapter item to the top of the Device Controller Priority option. To change the order of the devices, press and the up- or down-arrow key. If you want to revert to the original Boot Device Priority option settings, press . NOTE: If you exit the Device List option by pressing or without mak- ing any changes, the Boot Sequence option is set to the Device List option. )LJXUH6DPSOH'HYLFH/LVW6FUHHQ Boot Device Priority: Diskette drive A LANDesk Service Agent for 3C090X Hard drive C: CD-ROM device Level 2 Cache: System Memory: Video Memory: Service Tag: Asset Tag: Ctrl-Del original list Exclude from Boot Device Priority: The DEVICE LIST contains devices that may be bootable.
