6\VWHP2YHUYLHZ Dell® PowerEdge® 4300 systems are feature-rich, enterprise-class server systems that use Intel® Pentium® II microprocessor(s) with MMX™ technology and incorporate high-performance PCI and AGP local buses as well as the ISA expansion bus. The PowerEdge 4300 systems have been designed for better serviceability and increased reliability. The sliding system board tray allows easy access to the system board for performing processor and memory upgrades. The Dell- designed SCSI backplane board and hard-disk drive carriers eliminate the extensive cabling and drive configuration usually required for a SCSI sub- system. The plastic drive rails attached to devices mounted in the external drive bays allow you to remove these devices without removing a single screw. The systems can be either freestanding or rack-mounted. A PowerEdge 4300 system can contain one or two Pentium II microproces- sors. Each processor is housed in a single-edge contact (SEC) cartridge/heat sink assembly mounted in a guide bracket on the system board, allowing for greater heat dissipation. The processor has an internal operating frequency of 350 or 400 MHz (or a higher speed when available) and an external operating frequency of 100 MHz. Contact Dell for information about Dell-supported microprocessor upgrades. 6\VWHP)HDWXUHV In addition to the standard features found in a traditional personal computer, Dell PowerEdge 4300 systems include the following new and/or advanced features: ‡ One or two Intel Pentium II microprocessors with an internal operating fre- quency of 350 or 400 MHz (or higher speed when available) and an external bus speed of 100 MHz. NOTE: Do not attempt to operate the system with the microprocessor set to a speed other than the specified rating. ‡ Support for symmetric multiprocessing (SMP) when two microprocessors are installed. NOTE: The second microprocessor must have the same internal operating frequency as the first microprocessor. Not all versions of the Pentium II microprocessor will work properly as an additional microprocessor in this

system; the upgrade kit from Dell contains the correct version for this system. ‡ A secondary (L2) cache of 512 KB of SRAM included within the SEC car- tridge that contains the microprocessor. ‡ 64-MB and 128-MB (unbuffered) main memory, upgradable to 512 MB, or upgradable to 1 GB using 256-MB registered SDRAM DIMMs. ‡ BIOS in upgradable flash memory on the ISA bus. ‡ Up to six hot-pluggable SCSI hard-disk drives. Two additional 1-inch drives can be installed in the optional removable media bay. ‡ Up to three redundant, hot-pluggable power supplies and a power-supply paralleling board (PSPB), which is necessary for systems with two or more power supplies. ‡ Five redundant system cooling fans. ‡ Six 32-bit PCI connectors and two shared 8-bit or 16-bit ISA connectors. ‡ PCI and AGP local buses and ISA bus. ‡ A VGA-compatible video subsystem with an ATI 3D Rage Pro AGP video controller. This video subsystem contains 2 MB of SGRAM video memory (nonupgradable). ‡ A National Semiconductor PC87309 super I/O controller that controls the bidirectional parallel port, two serial ports, and the diskette drive in the externally accessible front bay. ‡ An integrated Adaptec AIC-7890 Ultra2/LVD SCSI-3 host adapter that sup- ports up to six 1.6-inch internal SCSI hard-disk drives via a SCSI backplane board and special SCSI hard-disk drive carriers. NOTE: The 1.6-inch drive carriers will accommodate 1-inch drives. The SCSI backplane automatically configures SCSI ID numbers and SCSI termination on individual hard-disk drives, greatly simplifying drive installa- tion. The backplane supports hot-pluggable SCSI hard-disk drive installation and removal when used in conjunction with a PowerEdge Expandable RAID Controller. ‡ An integrated Adaptec AIC-7860 Ultra/Narrow SCSI-3 host adapter that supports the standard CD-ROM drive and two additional externally accessi- ble SCSI devices in the external hard-disk drive bays. ‡ Drive failure, online, and activity indicators visible on each hard-disk drive connected to the SCSI backplane. ‡ Server management circuitry that monitors operation of the system fans as well as critical system voltages and temperatures. The server manage- ment circuitry works in conjunction with the HP OpenView Network Node Manager Special Edition (NNM SE) and the Dell OpenManage™ Hardware Instrumentation Package (HIP). ‡ System board support for the Dell OpenManage Remote Assistant when the optional Dell Remote Assistant Card version 2 (DRAC 2), which pro- vides additional local and remote server management, is installed.

$FFHVVLQJWKH,QWHULRURIWKH6\VWHP To access the SCSI backplane board or the PSPB, release the system-board tray latch at the back lower corner of the tray (see Figure 1-5) and pull the tray open to the first stop position (or service position). NOTE: From the service position, if you depress and release the tray latch and pull the tray out again, you will come to a second stop position that is used by manufacturing. To remove the tray completely from any position, depress the latch, hold it in, and pull the tray out of the chassis. )LJXUH2SHQLQJWKH6\VWHP%RDUG7UD\ system board tray SCSI backplane board tray latch

The system memory capacity can be expanded up to 1 GB by using combina- tions of 64- and 128-MB unbuffered SDRAM DIMMs or 256-MB registered SDRAM DIMMs. NOTE: DIMMs must be rated to run at 100 MHz. The system board has four 168-pin DIMM sockets. The DIMMs do not have to be inserted in pairs. The socket population guidelines are as follows: ‡ Populate the DIMM sockets in order from DIMM_A (right) to DIMM_D (left). ‡ The largest-capacity DIMM should be in socket DIMM_A, with smaller- capacity DIMMs installed in decreasing sizes toward socket DIMM_D. ‡ Unbuffered and registered DIMMs cannot be mixed. Remove any 64- or 128-MB unbuffered DIMMs before installing 256-MB registered DIMMs. ‡ DIMMs support the ECC feature, which detects memory errors and cor- rects single-bit memory errors. The ECC feature provides more reliable memory and less downtime. The ECC feature is built into the memory con- troller on the system board. )LJXUH',006RFNHWV For more detailed information about DIMM installation guidelines and samples of DIMM configurations, see “Adding Memory” in Chapter 8 of the Dell PowerEdge 4300 Systems Installation and Troubleshooting Guide. See “DIMMs” in Chapter 4 of this document for information on removing and replacing DIMMs. DIMM_A socket

$GYDQFHG([SDQVLRQ6XEV\VWHPV The computer system offers advanced expansion subsystems that can support a mixture of traditional ISA expansion cards, Plug and Play ISA expansion cards, and PCI expansion cards. The Resource Configuration Utility (RCU) included with the system provides a means of avoiding resource conflicts that might arise from such an arrangement. After all legacy cards have been configured with the RCU, the system automat- ically assigns any required memory space, IRQ lines, and DMA channels to any installed Plug and Play ISA expansion cards and PCI expansion cards the next time the system is rebooted. Chapter 5, “Using the Resource Configuration Utility,” in the Dell PowerEdge 4300 Systems User’s Guide describes the RCU and provides instructions for using it to configure the system. The expansion-card slots include six PCI expansion-card connectors and two ISA expansion-card connectors. Two of the PCI connectors share expansion- card slots with the two ISA connectors. The expansion-card connectors are located on the system board (see Figure 1-13). 9LGHR&RQWUROOHU The video subsystem is built into the system board and consists of an AGP VGA-compatible video subsystem with an ATI 3D Rage Pro SVGA video controller. The video subsystem contains 2 MB of SGRAM video memory, which is not upgradable. Noninterlaced resolutions are 640 x 480 (16.7 million colors), 800 x 600 (16.7 million colors), and 1024 x 768 (256 colors). ,QWHJUDWHG6&6,&RQWUROOHUV An integrated Adaptec AIC-7890 Ultra2/LVD SCSI-3 host adapter supports up to six 1- or 1.6-inch internal SCSI hard-disk drives through a 68-pin connector on the system board for a SCSI backplane board. The SCSI backplane board automatically configures SCSI ID numbers and SCSI termination on individual hard-disk drives, greatly simplifying drive installation. The integrated SCSI con- troller resides on the PCI local bus for optimum performance. An integrated Adaptec AIC-7860 Ultra/Narrow SCSI-3 host adapter attached to the PCI bus supports up to three SCSI devices in the external drive bays through a 50-pin connector on the system board. 6&6,+DUG'LVN'ULYHV Dell PowerEdge 4300 systems include a SCSI backplane board, which greatly simplifies cabling and configuration for SCSI hard-disk drives. SCSI ID and ter- mination for SCSI hard-disk drives are both configured by the SCSI backplane board, rather than on individual drives. SCSI hard-disk drives are supplied by Dell in special drive carriers that fit in the internal drive bays. NOTE: For maximum performance, install Ultra2/LVD drives exclusively. Although you can install a mixture of Ultra2/LVD and Ultra hard-disk drives, they will operate at the slower Ultra transfer rate.

‡ Disable termination on the drive. The SCSI backplane board provides termi- nation for the SCSI bus. ‡ Set the SCSI ID on all drives to 0. All SCSI ID numbers for the drives are set by the SCSI backplane board. ‡ Configure the drive so that the drive motor waits for a start unit command from the SCSI host adapter before spinning. SCSI devices (except hard-disk drives) in the external drive bays are controlled by the Ultra/Narrow SCSI controller on the system board. Hard-disk drives in the external drive bays are controlled by a RAID controller or the Ultra2/LVD SCSI connector via a two-device ribbon cable from the external drive bay insert’s backplane board. Although SCSI devices are installed essentially the same way as other devices, their configuration requirements are different. To configure SCSI devices installed in the external bays, follow the guidelines in the following subsections. 6&6,,'1XPEHUV Each device attached to the Ultra/Narrow SCSI host adapter must have a unique SCSI ID number from 0 to 7. When SCSI devices are shipped from Dell, the SCSI ID defaults are assigned as follows: ‡ The integrated Ultra/Narrow SCSI host adapter is configured through the BIOS as SCSI ID 7. ‡ A SCSI tape drive is configured as SCSI ID 6 (the default for a tape drive). ‡ A SCSI CD-ROM drive is usually configured as SCSI ID 5. NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in order by ID number. 'HYLFH7HUPLQDWLRQ All Dell PowerEdge 4300 systems have an active terminator installed at the end of the SCSI cable. All of the devices attached to the SCSI cable should have their termination disabled. 363%DQG6\VWHP3RZHU6XSSOLHV The Dell PowerEdge 4300 system provides one (when available as an option), two, or three 320-W system power supplies and, when necessary, a PSPB. See “System Power Supply” or “System Power Supply and PSPB Upgrade” in Chapter 4 for the installation procedure for this option.

When fully installed, a power supply automatically mates with a power harness attached to the back plate of the power supply cage. The power harness connects the power supply to the PSPB. The power supplies can operate from an AC power source of 115 VAC at 60 Hz or 230 VAC at 50 Hz. They provide the DC operating voltages and currents listed in Table 1-1. NOTE: The power supplies produce DC voltages only under their loaded condi- tion. Therefore, when you measure these voltages, the DC power connectors must be mated to their PSPB harnesses at the bulkhead, and the harnesses must be connected to their corresponding power input connectors on the PSPB. The PSPB, in turn, must be connected as appropriate to the system board, SCSI backplane board, or external drive bay. . 363% The PSPB multiplexes input from the power supplies to supply redundant power to the system board, SCSI backplane, and external drive bays. Through embedded server management (ESM), the PSPB can also be used to perform such tasks as detecting the presence of one to three power supplies; monitor- ing voltage and current outputs from the power supplies, voltage going to the 7DEOH'&9ROWDJHDQG&XUUHQW5DQJHV 9ROWDJH 5DQJH 0D[LPXP2XWSXW&XUUHQW1 +3.3 VDC +3.23 to +3.45 VDC 18.0 A +5 VDC +4.90 to +5.25 VDC 40.0 A +12 VDC +11.40 to +12.60 VDC 16.0 A –12 VDC –10.80 to –13.20 VDC 0.52 A –5 VDC –4.50 to –5.50 VDC 0.32 A +5 VFP +4.85 to +5.35 VDC 0.4 A 1 Maximum continuous combined load on +5 VDC and +3.3 VDC outputs cannot exceed 240 W. 2 Maximum combined load current on –5 VDC and –12 VDC outputs cannot exceed 0.6 A.

%DVLF7URXEOHVKRRWLQJ This chapter describes basic troubleshooting procedures that can help you diagnose a computer system problem. These procedures can often reveal the source of a problem or indicate the correct starting point for troubleshooting the system. For a brief explanation of how to load and start the system diag- nostics, see “Running the Dell Diagnostics” found later in this chapter. Dell recommends that you perform the following procedures in the order they are presented in this manual. :$51,1*7KHSRZHUVXSSOLHVLQWKLVFRPSXWHUV\VWHPSURGXFHKLJK YROWDJHVDQGHQHUJ\KD]DUGVZKLFKFDQFDXVHERGLO\KDUP2QO\ WUDLQHGVHUYLFHWHFKQLFLDQVDUHDXWKRUL]HGWRUHPRYHWKHFRPSXWHU FRYHUDQGDFFHVVDQ\RIWKHFRPSRQHQWVLQVLGHWKHFRPSXWHU ,QLWLDO8VHU&RQWDFW When you first contact a user who has a problem, ask the user to describe the problem and the conditions under which it occurs. A verbal description can often indicate the cause of a problem or indicate the appropriate troubleshoot- ing procedure to use. After the user describes the problem, follow these steps: 1. Ask the user to back up any data on the hard-disk drive if the system’s con- dition permits. Appendix C, “Maintaining the System,” in the User’s Guide provides infor- mation about backing up data. 2. Ask the user to try to duplicate the problem by repeating the operations he or she was performing at the time the problem occurred. Can the user duplicate the problem? Yes. Proceed to step 3. No. Proceed to the next section, “External Visual Inspection.”

3. Observe the user to determine if he or she is making an error, such as typ- ing an incorrect key combination or entering a command incorrectly. Is the problem a result of user error? Yes. Instruct the user in the proper procedure, or direct him or her to the appropriate user documentation for the correct procedure. No. Proceed to the next section, “External Visual Inspection.” ([WHUQDO9LVXDO,QVSHFWLRQ The external visual inspection consists of a quick inspection of the exterior of the computer, the monitor, the keyboard, any peripherals, and cables. While performing the visual inspection, make any necessary corrections. To perform the external visual inspection, follow these steps: 1. Turn off the computer, the monitor, and all peripherals. 2. Verify that all power cables are properly connected to the computer, the monitor and peripherals, and their power sources. 3. Verify that the keyboard and mouse interface cables are firmly attached to the proper connectors on the back of the computer. For a PS/2-compatible mouse, the keyboard and mouse interface cable connectors are identical except for their labels. If needed, see “System Features” in Chapter 1. For a serial mouse, the mouse interface cable must be firmly attached to one of the serial port connectors, and its captive screws must be secure enough to ensure a firm connection. 4. If any network cables are present, verify that they are attached properly. 5. Verify that any devices attached to the serial and parallel port connectors are properly connected. Each of the serial and parallel port interface cables must be firmly attached to an appropriate connector on the back of the computer as well as to the interface connector on the device. The captive screws that secure these connectors at each end of the interface cable must be secure enough to ensure a firm connection. 6. Verify that the video interface cable is firmly attached to the video connec- tor on the back panel or to a video expansion card, and also to the connector on the back of the monitor. For proper connection of the video monitor, see the documentation for the monitor.

settings. For proper settings of the video monitor controls, see the documentation for the monitor. 8. Inspect the keyboard to ensure that no keys are sticking. If one or more keys are sticking, it may be necessary to replace the keyboard. 9. Inspect the exterior of the computer, including all controls and indicators, and all user-accessible data storage devices for any signs of physical damage. Does the inspection reveal any problems? Yes. Proceed to the appropriate procedure in Chapter 4, “Removing and Replacing Parts.” No. Proceed to the next section, “Observing the Boot Routine.” 2EVHUYLQJWKH%RRW5RXWLQH After you have performed an external visual inspection as described in the pre- vious section, you should boot the system and, while the boot routine is running, observe the system for any indications of problems. NOTES: Most of the steps in this procedure require observation of system functions and indications, some of which can occur simultaneously. It may be necessary to reboot the system several times to complete all of these steps. To perform the following procedure, you need a Dell Diagnostics Diskette cre- ated from the Dell Server Assistant CD. If such a diskette is not available, you can create it as described in “Create Diskettes” in Chapter 2 of the User’s Guide. If a separate diagnostics diskette is included with the system, you may need to use that diskette. To observe problem indications during the boot routine, follow these steps: 1. If the system is off, turn on all peripherals and the computer. Insert the Dell Diagnostics Diskette into the diskette drive and reboot the system. 2. Check each power supply fan. Does the fan run normally? Yes. Proceed to step 3. No. Troubleshoot the system power supplies.

3. Watch the Num Lock, Caps Lock, and Scroll Lock indicators on the upper- right corner of the keyboard. After all three indicators flash momentarily, and following a long pause (approximately 30 seconds), the Num Lock indi- cator should light up and remain on (unless the Num Lock option is set to Off in the System Setup program). Do these indicators flash on and off within approximately 10 seconds after the boot routine starts? Yes. Proceed to step 4. No. Troubleshoot the system power supplies. If the troubleshooting pro- cedure indicates that the system power supplies are operational, troubleshoot the memory. 4. During the boot routine, observe the system for any of the following: ‡ Beep codes: A beep code is a series of beeps that indicates an error condition. If the system emits a beep code, see Table 3-1 later in this manual. ‡ System error messages: These messages can indicate problems or provide status information. If a system error message is displayed, see Table 3-2 later in this manual. ‡ Diskette-drive and hard-disk drive access indicators: These indicators light up in response to data being transferred to or from the drives. If either of these indicators fails to light up during the boot routine, troubleshoot the diskette drive or hard-disk drive subsystem, as appropriate. 5. Observe the monitor screen for the Diagnostics Menu. Does the Diagnostics Menu appear? Yes. See “Running the Dell Diagnostics” found later in this chapter. No. Proceed to step 6. 6. Insert another copy of the Dell Diagnostics Diskette into the diskette drive, and reboot the system. Does the Diagnostics Menu appear? Yes. See “Running the Dell Diagnostics” found later in this chapter. No. Proceed to the next section, “Internal Visual Inspection.”

the source of a problem, such as a loose expansion card, cable connector, or mounting screw. When you perform the visual inspection, refer to “System Features” in Chapter 1 to locate components referenced in the inspection procedure. To perform the internal visual inspection, follow these steps: 1. Turn off the system, including any attached peripherals, and disconnect all the AC power cables from their power sources. :$51,1*%HIRUHEHJLQQLQJWRZRUNLQVLGHWKHFRPSXWHUGLVFRQQHFW WKHSRZHUVXSSO\IURPWKHSRZHUVRXUFHDQGWKHSRZHUVXSSO\FDEOHV IURPWKHSRZHUVXSSO\ 2.

Verify that the chips, DIMMs, expansion cards, and SEC cartridge and heat sink assembly or assemblies are fully seated in their sockets or connectors. To ensure that the chips are fully seated in their sockets, press firmly on the top of each chip. To reseat an SEC cartridge and heat sink assembly, remove and re- install it as described in “SEC Cartridge and Heat Sink Assembly” in Chapter 4. To reseat a DIMM, remove it from its socket and reinstall it as described in “DIMMs” in Chapter 4.

If you need to reseat an expansion card, remove the card as described in “Expansion Cards” in Chapter 4, and then reinsert the card in its connector and carefully push it in until fully seated. 4. Verify that all jumpers are set correctly. For information about jumper settings, see “System Board Jumpers” in Chapter 1. 5. Check all cable connectors inside the computer to verify that they are firmly attached to their appropriate connectors. 6. Reinstall the computer cover. 7. Reconnect the computer and any attached peripherals to their power sources, and turn them on. Does the problem appear to be resolved? Yes. No further steps are necessary. No. Proceed to the next section, “Eliminating Resource Conflicts,” and to “Getting Help” found later in this chapter. (OLPLQDWLQJ5HVRXUFH&RQIOLFWV Devices within the computer may require dedicated memory spaces, interrupt levels, or DMA channels, all of which must be allocated during installation of the devices. Because devices may be installed at different times, it is possible that the same resource is assigned to two or more devices. Resource conflicts can result in disorderly or erratic system operation or sys- tem failure. If you suspect that resource conflicts might exist, check the system and reassign the resources as necessary. For additional information, see Chapter 5, “Using the Resource Configuration Utility,” in the User’s Guide or “Interrupt Assignments” and “DMA Channel Assignments” in Chapter 1 of this manual. 5XQQLQJWKH'HOO'LDJQRVWLFV The Dell Diagnostics contains tests that aid in troubleshooting all major com- ponents of the computer system. To run the tests, you must first create the Dell Diagnostics Diskette using the Dell Server Assistant CD as described in “Create Diskettes” in Chapter 2 of the User’s Guide. If a separate Dell Diag- nostics Diskette is included with the system, you may need to use that diskette. To start the Dell Diagnostics, turn off the system, insert the Dell Diagnostics Diskette into the diskette drive, and then turn on the system.

If a RAM error is detected, a mes- sage telling you which DIMM has failed appears on the screen. If no errors are found in RAM, the diagnostics loads and the Diagnostics Menu appears. This menu lets you choose the following options or exit the Dell Diagnostics: ‡ Run All Tests — Runs all tests for a thorough check of the system ‡ Run Quick Tests — Runs selected tests from all test groups to quickly locate a failure or to indicate where further testing is needed to isolate a failure ‡ Run Specific Tests — Tests a particular area or subsystem *HWWLQJ+HOS If none of the troubleshooting procedures in this chapter or the tests in the Dell Diagnostics reveals the source of the problem or leads to the proper troubleshooting steps for determining the source of the problem, refer to the Support site at www.dell.com or call Dell for technical assistance.

3-1 & + $ 3 7 ( 5   &RGHVDQG0HVVDJHV This chapter describes beep codes, system messages, alert messages from the Dell OpenManage Hardware Instrumentation Package (HIP) application program, and SCSI hard-disk drive indicator codes that can occur during the POST or during normal system operation. If a faulty system does not emit beep codes or display system messages to indicate a failure, you should use the Dell Diagnostics to run the appropriate tests to help isolate the source of the problem. See Chapter 5, “Running the Dell Diagnostics,” in the Installation and Troubleshooting Guide. 3267%HHS&RGHV If the monitor cannot display error messages during the POST, the system may emit a series of beeps that identifies the problem or that can help you identify a faulty component or assembly. Table 3-1 lists the beep codes that may be generated during the POST. Most beep codes indicate a fatal error that pre- vents the system from completing the boot routine until the indicated condition is corrected. When the system emits a beep code, record the code and then find it in Table 3-1. If the table does not lead to the source of the problem, run the appropriate tests in the Dell Diagnostics to assist in troubleshooting the problem.

A-1 $ 3 3 ( 1 ' , ;  $ 6\VWHP6HWXS3URJUDP This appendix describes the System Setup program, which is used to change the system configuration information stored in NVRAM on the system board. For in-depth information, refer to Chapter 4, “Using the System Setup Pro- gram” in the Dell PowerEdge 4300 Systems User’s Guide. To enter the System Setup program, follow these steps: 1. Turn on (or reboot) the system. 2. Press immediately after you see the message 3UHVV &WUO!$OW!(QWHU!IRU6\VWHP6HWXS. If you wait too long, the operating system begins to load into memory, the message disappears, and you cannot enter the System Setup program. Let the system complete the load operation; then shut down the system and try again. NOTE: To ensure an orderly system shutdown, consult the documentation that accompanied the operating system.

A-3 7DEOH$6\VWHP6HWXS2SWLRQV 2SWLRQ )XQFWLRQ Time Resets time on computer’s internal clock. Date Resets date on computer’s internal calendar. Diskette Drive A Diskette Drive B Identifies type of diskette drives installed. Tape drives are not reflected. Reserved Memory Allows a region of system board memory to be supplied by an expansion card with 15M - 16M or None (default). CPU Speed Indicates the processor speed at which the system boots (can toggle to a lower speed). This option should be used only for trouble- shooting purposes; otherwise, do not use. Num Lock On 101- and 102-key keyboards, determines whether system boots with Num Lock acti- vated (does not apply to 84-key keyboards). Processor 1 Processor 2 Displays version or stepping number of the microprocessor in each processor slot on the system board. Fan Speed Sets the fan speed to Full Speed (default) or Noise Reduced. System Alert Sets the system LED to flash when a critical (Fault, the default) or noncritical (Warning) error threshold is passed. Keyboard Errors Enables or disables reporting of keyboard errors during POST. Boot Sequence Determines whether system boots from dis- kette (if present) or hard-disk drive. Scan Sequence Determines the order in which the PCI devices are scanned by the system. System Password Displays current status of system’s password security feature. Also used to assign and verify a new password. The system password is overridden by the setup password. Password Status If set to Locked, prevents the system pass- word from being changed or disabled. Requires that Setup Password option be set to Enabled. Setup Password Restricts access to System Setup program. The setup password overrides the system password. Mouse Enables or disables the built-in PS/2- compatible mouse port.

Serial Port 1 Serial Port 2 Configures system’s built-in serial ports. These options may be set to Auto (default) to automatically configure a port, to a specific designation (COM1 [3F8h] or COM3 [3E8h] for Serial Port 1; COM2 [2F8h] or COM4 [2E8h] for Serial Port 2), or to Off. Parallel Port Configures system’s built-in parallel port. The port’s I/O address may be set to 378h (default), 278h, 3BCh, or to Off to disable the port. Parallel Mode Controls whether system’s built-in parallel port acts as an AT-compatible (unidirectional) or PS/2-compatible (bidirectional) port. Diskette Controls operation of the system’s built-in dis- kette controller. Speaker Determines whether the built-in speaker is On (default) or Off. Primary SCSI Secondary SCSI Turns the respective SCSI controllers on or off. Selecting On (default) enables a controller and allows scanning of the devices connected to it, allowing the device with the lowest SCSI ID to function as a boot device (unless a boot device connected to an enabled controller higher in the scan sequence has already been detected). Selecting Off causes the BIOS to mask the presence of a controller. Processor field Displays microprocessor type and speed. Level 2 Cache Displays size of integrated cache. System Memory Displays entire amount of installed memory detected in system, except for memory on EMS expansion cards. Video Memory Displays amount of video memory detected. Service Tag Displays system’s five-character service tag number. Asset Tag Displays the asset tag number if one is assigned. 7DEOH$6\VWHP6HWXS2SWLRQVFRQWLQXHG 2SWLRQ )XQFWLRQ
