Back to Contents Page Using the System Setup Program: Dell ™ Latitude™ CPi A-Series System User's Guide Overview | Entering the System Setup Program | Using the System Setup Program | System Setup Options Overview Each time you turn on your computer, it compares the installed hardware with the system configuration information stored in nonvolatile random-access memory (NVRAM). If the system detects a discrepancy, it generates an error message for each incorrect configuration setting.
If you are using Windows NT 4.0, close all open application programs and exit the operating system. When prompted, reboot the computer and press < F1> (or from an external keyboard if the External Hot Key option is enabled). If you wait too long and your operating system begins to load into memory, let the system complete the load operation; then shut down the computer and try again. In either operating system, press to exit the System Setup program.
AC AC, a category under Power Management, allows you to set different time-outs for the following options when you operate your computer from AC power: Display Time-Out, Disk Time-Out, Suspend Time-Out, S2D Time-Out, Smart CPU Mode, and Brightness. A change to the AC option takes effect immediately (rebooting is not required). Admin Password Admin Password displays the current status of your administrator password and allows you to assign or change this password.
Disabled (the default) — Disables the audio controller and makes the direct memory access (DMA),interrupt request (IRQ), and input/output (I/O) resources available for another serial device to use. Full Duplex — Allows the computer's audio system to play and record sounds simultaneously. For a change in the Audio Mode option to take effect, you must reboot your computer.
Settings for this option are: Diskette Drive (the default) — Causes your computer to attempt first to boot from a bootable diskette. Internal HDD — Causes your computer to boot from the hard-disk drive. CD-ROM Drive — Causes your computer to attempt first to boot from a bootable CD-ROM disk. Modular Bay HDD — Attempt first to boot from the second hard-disk drive installed in the modular bay. For a change in the Boot First Device option to take effect, you must reboot your computer.
For a change in the Boot Speed option to take effect, you must reboot your computer. Brightness Brightness allows you to specify the brightness of the display when the computer is operating on battery power. Use the left- and right-arrow keys to change the brightness of the display. When the computer is powered by a battery, the default setting for Brightness is Minimum. If the computer is using AC power, the default setting is Maximum.
software requires frequent hard-disk drive accesses, using a higher time-out setting may save battery power and time by minimizing the number of times the hard-disk drive must power up.

properly setting and clearing individual bits in RAM. It also determines whether the RAM read and write operations are affecting more than one memory address location at a time. This subtest checks all available RAM, including the secondary cache.
Subtests The 11 subtests in the System Set test group confirm the following computer functions: CMOS Confidence Test Checks the nonvolatile RAM (NVRAM) for accessibility and reliability of data storage by performing a data pattern check and verifying the uniqueness of memory addresses. DMA Controller Test Tests the direct memory access (DMA) controller and verifies the correct operation of its page and channel registers by writing patterns to the registers.
Video Test Group The subtests in the Video test group verify the proper operation of the video controller and the video control circuitry installed in the computer. These subtests check for the correct operation of the readable registers in the video circuitry and the controller. They write, read, and verify data patterns in the cursor registers of the controller. The Video test group also provides additional subtests to test the color features of the color display or an external color monitor.
Graphics Mode Test Checks the video subsystem's ability to present data and color in graphics modes Color Palettes Test Checks the video subsystem's ability to display all of the available colors Solid Colors Test Checks the video subsystem's ability to show screens full of solid colors and allows you to check for missing color pixels Many of these tests display characters or graphics on the screen for you to verify.

Very often, a diskette drive problem may first appear to be a diskette problem. A box of defective diskettes might produce faulty-drive error messages. The test results can be confusing, so you should run the subtests in the Diskette Drives test group more than once using diskettes from different sources. Another possible cause of diskette drive problems is human error—for example, typing a command in an incorrect form (usually called a syntax error). Be sure you have entered the command properly.
disk drive. These are the most common symptoms that might prompt you to test the hard-disk drive: The hard-disk drive fails during the boot routine. Seek errors are reported by the operating system or application programs. An error message appears on the screen stating that the computer cannot read from or write to the hard-disk drive. Data on the hard-disk drive is corrupted or lost; these problems may be intermittent. Once saved by a program, files cannot be properly recalled.
disc or from the drive. When you encounter problems, first try using a different CD. If the problem recurs, run the IDE CD-ROM Drives test group. These are the most common symptoms that might prompt you to test an IDE CD-ROM drive: Seek errors are reported by the operating system or application programs. An error message appears on the screen stating that the computer cannot read from an IDE CD-ROM drive.
If the diagnostics do not recognize the computer's serial or infrared port, check the Serial Port or Infrared Data Port option in the System Setup program to see if the port has been disabled. For instructions, see Serial Port, Infrared Data Port, or Parallel Mode. The subtests in the Serial/Infrared Ports test group cannot test a port unless it is enabled. Another possible cause for errors is a problem with the external device itself.
System Setup program to see if the port has been disabled. The subtests in the Parallel Ports test group cannot test a port unless it is enabled. When a port is faulty, it may not be immediately evident that the port, and not the device connected to the port, is faulty. Instead, the peripheral (such as a printer) might behave erratically or not operate at all. Also, if the external device is not properly installed through software, it may not function properly.
(SCSI) controller in the C/Port APR or C/Dock Expansion Station, and the SCSI devices attached to either. These tests run only if the computer is docked. NOTES: Before conducting these subtests on an external SCSI CD-ROM drive, insert into the drive a CD with audio and data tracks (such as a multimedia CD). The Audio Output Test requires a CD with audio tracks; all other subtests require a CD with data tracks.
Causes the drive to begin playing the first audio track on an audio CD. (To determine if the test passed, listen to the audio output of the drive.) NOTE: The Audio Output Test does not run automatically as part of the SCSI Devices test group; you must select this subtest individually. Eject Removable Media Test Causes a CD-ROM drive to eject its CD, or a SCSI tape drive to eject its tape cartridge.
Shared RAM Test Performs a memory test on controllers with memory-mapped shared RAM. On controllers with first-in first-out (FIFO) shared RAM, writes a data pattern to all locations and reads the pattern back to verify the operation. Some controllers do not support shared RAM tests.

If the system detects a discrepancy, it generates an error message for each incorrect configuration setting.
If you are using Windows NT 4.0, close all open application programs and exit the operating system. When prompted, reboot the computer and press < F1> (or from an external keyboard if the External Hot Key option is enabled). If you wait too long and your operating system begins to load into memory, let the system complete the load operation; then shut down the computer and try again. In either operating system, press to exit the System Setup program.
AC AC, a category under Power Management, allows you to set different time-outs for the following options when you operate your computer from AC power: Display Time-Out, Disk Time-Out, Suspend Time-Out, S2D Time-Out, Smart CPU Mode, and Brightness. A change to the AC option takes effect immediately (rebooting is not required). Admin Password Admin Password displays the current status of your administrator password and allows you to assign or change this password.
Disabled (the default) — Disables the audio controller and makes the direct memory access (DMA),interrupt request (IRQ), and input/output (I/O) resources available for another serial device to use. Full Duplex — Allows the computer's audio system to play and record sounds simultaneously. For a change in the Audio Mode option to take effect, you must reboot your computer.
Settings for this option are: Diskette Drive (the default) — Causes your computer to attempt first to boot from a bootable diskette. Internal HDD — Causes your computer to boot from the hard-disk drive. CD-ROM Drive — Causes your computer to attempt first to boot from a bootable CD-ROM disk. Modular Bay HDD — Attempt first to boot from the second hard-disk drive installed in the modular bay. For a change in the Boot First Device option to take effect, you must reboot your computer.
For a change in the Boot Speed option to take effect, you must reboot your computer. Brightness Brightness allows you to specify the brightness of the display when the computer is operating on battery power. Use the left- and right-arrow keys to change the brightness of the display. When the computer is powered by a battery, the default setting for Brightness is Minimum. If the computer is using AC power, the default setting is Maximum.
software requires frequent hard-disk drive accesses, using a higher time-out setting may save battery power and time by minimizing the number of times the hard-disk drive must power up. NOTE: Set Disk Time-Out to Disabled if using it causes compatibility problems with your software. A change to the Disk Time-Out option takes effect immediately (rebooting is not required). If you are not in the System Setup program, you can turn off the hard-disk drive immediately by pressing .
2 Minutes 3 Minutes 4 Minutes 15 Minutes 30 Minutes 1 Hour The default setting is 4 Minutes. To increase battery operating time, set Display Time-Out to a lower number of minutes.

A change to the Display Time-Out option takes effect immediately (rebooting is not required). If you are not in the System Setup program, you can turn off the display immediately by pressing .
NOTES: The System Setup program limits the options available for Infrared Mode, depending on how the Parallel Mode and Audio Mode options are set. If Parallel Mode is set to ECP and Audio Mode is set to Full Duplex, the Infrared Mode option cannot be set to Fast IR. This limitation is based on the number of available 8-bit DMA channels. The value selected for Infrared Mode determines the boot configuration for the device.
NOTE: The ECP setting also works for most software written for the AT and PS/2 modes. Devices that use ECP mode may come with special drivers that need to be installed in order to use these modes. Setting Parallel Mode to Disabled disables the parallel port and its assigned LPT address, freeing its interrupt for another device to use. For a change in the Parallel Mode option to take effect, you must reboot your computer.

Text Mode Character Test The Text Mode Character Test consists of a group of subtests that display printable characters and character attributes. The subtests check character quality and the ability of the display or monitor to show the characters correctly. A prompt at the bottom of each screen asks you to decide whether the display is satisfactory and to respond by typing y or n. If you respond affirmatively to each subtest, the Text Mode Character Test passes.
Text Mode Color Test The Text Mode Color Test contains three subtests that check the video subsystem's ability to present color in text modes. The following subsections describe these subtests. Color Attributes Subtest (80 x 25) The 80-column by 25-line color attributes subtest displays a pattern of 16 rows and 16 columns in 80-column by 25-line text mode. Each row has a hexadecimal number in a unique foreground color, and each column has a unique background color.

When to Use the Dell Diagnostics Whenever a major component or device in the computer does not function properly, the component or device may have failed. As long as the microprocessor and input/output (I/O) components of the computer (the display, keyboard, and diskette drive) are working, use the Dell Diagnostics. If you are experienced with computers and know which component(s) you need to test, select the appropriate diagnostic test group(s) or subtest(s).
4. Place the Dell Diagnostics Diskette in the diskette drive and boot the computer. NOTE: Before you read the rest of this chapter, you may want to start the Dell Diagnostics so you can see the menus on your display. When you start the diagnostics, the Dell logo screen appears, and a program tests the random-access memory (RAM) that will be used by the diagnostics. If a failure in RAM is detected, a message appears on the screen that tells you the memory address of the defective memory module.
Two lines at the top of the screen identify the diagnostics and give its version number. On the left side of the screen, the Available Test Groups area lists the diagnostic test groups in the order they will be run if you select Run and then All. Press the up- or down-arrow key to highlight a test group. On the right side of the screen, the System Configuration area lists the computer's current hardware settings.

properly setting and clearing individual bits in RAM. It also determines whether the RAM read and write operations are affecting more than one memory address location at a time. This subtest checks all available RAM, including the secondary cache.
Subtests The 11 subtests in the System Set test group confirm the following computer functions: CMOS Confidence Test Checks the nonvolatile RAM (NVRAM) for accessibility and reliability of data storage by performing a data pattern check and verifying the uniqueness of memory addresses. DMA Controller Test Tests the direct memory access (DMA) controller and verifies the correct operation of its page and channel registers by writing patterns to the registers.
Video Test Group The subtests in the Video test group verify the proper operation of the video controller and the video control circuitry installed in the computer. These subtests check for the correct operation of the readable registers in the video circuitry and the controller. They write, read, and verify data patterns in the cursor registers of the controller. The Video test group also provides additional subtests to test the color features of the color display or an external color monitor.
Graphics Mode Test Checks the video subsystem's ability to present data and color in graphics modes Color Palettes Test Checks the video subsystem's ability to display all of the available colors Solid Colors Test Checks the video subsystem's ability to show screens full of solid colors and allows you to check for missing color pixels Many of these tests display characters or graphics on the screen for you to verify. Samples of these screens are shown in Diagnostic Video Tests.

Very often, a diskette drive problem may first appear to be a diskette problem. A box of defective diskettes might produce faulty-drive error messages. The test results can be confusing, so you should run the subtests in the Diskette Drives test group more than once using diskettes from different sources. Another possible cause of diskette drive problems is human error—for example, typing a command in an incorrect form (usually called a syntax error). Be sure you have entered the command properly.
disk drive. These are the most common symptoms that might prompt you to test the hard-disk drive: The hard-disk drive fails during the boot routine. Seek errors are reported by the operating system or application programs. An error message appears on the screen stating that the computer cannot read from or write to the hard-disk drive. Data on the hard-disk drive is corrupted or lost; these problems may be intermittent. Once saved by a program, files cannot be properly recalled.
disc or from the drive. When you encounter problems, first try using a different CD. If the problem recurs, run the IDE CD-ROM Drives test group. These are the most common symptoms that might prompt you to test an IDE CD-ROM drive: Seek errors are reported by the operating system or application programs. An error message appears on the screen stating that the computer cannot read from an IDE CD-ROM drive.
If the diagnostics do not recognize the computer's serial or infrared port, check the Serial Port or Infrared Data Port option in the System Setup program to see if the port has been disabled. For instructions, see Serial Port, Infrared Data Port, or Parallel Mode. The subtests in the Serial/Infrared Ports test group cannot test a port unless it is enabled. Another possible cause for errors is a problem with the external device itself.
System Setup program to see if the port has been disabled. The subtests in the Parallel Ports test group cannot test a port unless it is enabled. When a port is faulty, it may not be immediately evident that the port, and not the device connected to the port, is faulty. Instead, the peripheral (such as a printer) might behave erratically or not operate at all. Also, if the external device is not properly installed through software, it may not function properly.
(SCSI) controller in the C/Port APR or C/Dock Expansion Station, and the SCSI devices attached to either. These tests run only if the computer is docked. NOTES: Before conducting these subtests on an external SCSI CD-ROM drive, insert into the drive a CD with audio and data tracks (such as a multimedia CD). The Audio Output Test requires a CD with audio tracks; all other subtests require a CD with data tracks.
Causes the drive to begin playing the first audio track on an audio CD. (To determine if the test passed, listen to the audio output of the drive.) NOTE: The Audio Output Test does not run automatically as part of the SCSI Devices test group; you must select this subtest individually. Eject Removable Media Test Causes a CD-ROM drive to eject its CD, or a SCSI tape drive to eject its tape cartridge.
Shared RAM Test Performs a memory test on controllers with memory-mapped shared RAM. On controllers with first-in first-out (FIFO) shared RAM, writes a data pattern to all locations and reads the pattern back to verify the operation. Some controllers do not support shared RAM tests. Display Information Test Displays address and configuration information about the network controller.
DMA Test Tests for the presence of a DMA channel on the system chip set, and determines if the DMA controller and the audio controller can exchange signals FM Sound Playback Test Tests whether the system can synthesize sounds and play them through the built-in speakers Analog Sound Playback Test Tests whether the system can play sampled sounds through the built-in speakers Record and Playback Test Checks the ability of the audio controller to generate a sampled sound from signals received from the built-in
