  • Page 191 CAUTION: It is important that you quit the diagnostics program correctly, because the program writes data to the computer's memory that can cause problems unless properly cleared. Tests in the Dell Diagnostics The diagnostics is organized by components into test groups and subtests within each test group. Each subtest is designed to detect any errors that may interfere with the normal operation of a specific device of the computer.

Table 3. RAM Test Switches Switch Description -r number Repeats the subtest this number of times. Valid numbers are 1 through 9999. A value of 0 causes the test to run until you press <Ctrl><Break>.
  • Page 195 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. The Comprehensive Test also performs an address check, as well as the following: Data pattern checks, to look for RAM bits that are stuck high or low, short-circuited data lines, and some data pattern problems that are internal to the memory chips...
  • Page 196 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.
  • Page 197 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.
  • Page 198 Keyboard test group. (Clear them from memory by booting the computer from the Dell Diagnostics Diskette.) When these possibilities have been eliminated, and if the following symptoms occur, you should run one or more of the subtests in the Keyboard test group: When you press a key, the character represented by that key appears repeatedly;...

  • Page 200 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).
  • Page 201 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.
  • Page 202 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.
  • Page 203 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.
  • Page 204 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.
  • Page 205 (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).
  • Page 206 The subtests in the Network Interface test group verify the basic operation of the network interface controller in the Dell Latitude C/Port APR or C/Dock Expansion Station. They test the controller's internal functions, including read and write access to its registers and internal transmit and receive (loopback) capability. These tests run only if the computer is docked.
  • Page 207 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.
  • Page 208 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...
