2 System Troubleshooting 2.1 Introduction This chapter describes troubleshooting of the applicationDEC 400xP system. It contains the following sections: • Diagnostic tools • Power-on self-test • Setup utility • Run-time error messages • Troubleshooting 2.2 Diagnostic Tools Table 2–1 lists the diagnostic tools required to service the applicationDEC 400xP system. Table 2–1 Diagnostic Tools Tool Part Number Description System Configuration Utility Diskette (APPLICATIONDEC 400 XP SYS 2.
2.3 Power-On Self-Test Before the applicationDEC 400xP system can be used, all components must be initialized and tested, and the operating system must be loaded into memory. The BIOS that is stored in ROM controls this sequence of actions. A portion of the BIOS contains a power-on self-test (POST). POST is responsible for initializing and testing system components each time power is applied or when the system boots. The remainder of the BIOS loads the operating system and specific applications.
2.3.2 Peripheral Hardware Tests The first peripheral hardware test procedure verifies that the system configuration data stored in CMOS RAM matches the hardware present. Then, the procedures continue to test and initialize other peripheral hardware. This testing includes memory on the system board and, if one is installed, the memory module. A test failure generally results in an error message on the monitor screen.
If POST does not detect any configuration errors, the system beeps once and displays a message similar to the following: PhoenixBIOS (TM) E486 Version x.xx.xx.xxx Copyright (c) 1985-1991 Phoenix Technologies Ltd. All Rights Reserved . . . 640K Base Memory 03072K Extended 000 To continue press:.................................SPACEBAR To configure system press:...............................
2.3.4 POST and Boot Messages POST displays messages to alert you to errors in hardware, software, and firmware. It also displays information about your system. During POST, the system board speaker beeps to alert you to specific POST steps. Two beeps signal the start of the time during which you can enter setup. Another beep signals the end of that time, and then a subsequent beep signals that a system boot has begun. If an error occurs during POST, the countdown is stopped.

3 System Exerciser 3.1 Overview The applicationDEC system exerciser (SYSEX) is a standalone, diskettebased diagnostic that detects and isolates hardware problems to the field replaceable unit (FRU) level. SYSEX tests each system unit simultaneously with peripheral and communication transfers to detect interactive errors. Note Version 4.0 or higher of the applicationDEC System Exerciser is required for use with the applicationDEC 400xP system.
• Digital hard disk drives: 209 MB disk drive (RZ24) 426 MB disk drive (RZ25) 665 MB disk drive (RZ56) 852 MB disk drive (RZ35) 1.0 GB disk drive (RZ57) 1.3 GB disk drive (RZ58) You can run the system exerciser two ways: • The installation verification procedure (IVP) performs a 15-minute (default time) test session that returns the system status. • The run command executes the system exerciser tests continuously. Press Ctrl/C to halt SYSEX at any time.
3.3 Running the System Exerciser Note Before you run SYSEX, verify the system configuration with the system configuration utility (SCU). For information on configuring the system with the SCU, refer to Chapter 5. When the system exerciser has been booted, system configuration information is displayed on the screen: 03/12/92 15:00:08 applicationDEC System Exerciser Rev 4.0 400xP applicationDEC System Exerciser Rev 4.
Then you are prompted to select destructive (write/read) or nondestructive (read only) testing for each device: Test mode selection. Use keyboard to make selections. Space key selects write/read testing. ENTER key protects media. The screen should resemble the following display during and after test mode selections: BUS Configuration: Slot ID LUN Device 0 0 * Disk 0 1 * Disk 3 0 0 Disk 3 1 0 Disk Type Rev Selection RX23/1.44M Protected RX33/1.
Scheduled tests: Test ==== 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. Name Rev ==== === Memory 1 Memory Retention 1 Numeric 0 Serial Line (COM1) 2 Serial Line (COM2) 2 Motherboard [Slot 0] 2 Parallel Port (LPT1) 1 Console 1 SCSI Disk 3:0:0 1 SCSI Disk 3:1:0 1 Floppy Disk 0:0 1 Floppy Disk 0:1 1 8x4 Mux [Slot 11] 2 Ethernet/2 (DE200) 0 Type "HELP" for information, "RUN" or "IVP" to begin testing HLT> When the HLT> prompt is displayed, you can run the 15-minute installation verification procedure (IVP).
3.4 Loading Failure After you load SYSEX, one or two messages appear on the console monitor. If the only message is the following, loading was successful: Verifying program loaded correctly If the error report ‘‘Checksum error detected at load time’’ follows the above message, the loading failed. Take the following action: 1. Reload the diskette. 2. Reboot. If this fails to correct the loading failure, try a different SYSEX diskette in case the first diskette is bad. 3.
The following SYSEX error report shows that the loopback plug was found missing during external loopback testing of serial port 1 (COM1): applicationDEC System Exerciser Rev: 4.
3.6 Test Descriptions Table 3–1 describes the system exerciser tests. Table 3–1 System Exerciser Tests Name Description Memory Write/read main memory. Memory retention Memory refresh circuitry. Numeric CPU floating point. Motherboard System motherboard logic. Console Writes test patterns to the console for visual verification. Terminal multiplexer Internal/external data loopback and registers. Serial port (COM1, COM2) Internal/external data loopback and registers.
You can place SYSEX in the halt mode at any time by pressing Ctrl/C . Because no tests are running when SYSEX is in the halt mode, response to commands is immediate. When SYSEX is in the run mode and tests are running, the keys you press are echoed to the screen as they are typed, but the commands are not executed until the completion of the current test pass. This can sometimes cause a short delay. 3.
Use the flag command to change the status of a flag. For example, to set the long flag, enter the following: HLT> flag on long Enter If you boot the system, the SYSEX flags return to the default settings. 3.9 Commands Table 3–4 lists the system exerciser commands. The commands are not case sensitive and may be abbreviated. Table 3–4 System Exerciser Commands Command Description B[lock] Prevent specified tests from running.
Table 3–4 (Cont.) System Exerciser Commands Command Description L[og] Play back or delete previous error reports or write error reports to a DOS diskette. Q[uit] or Ctrl/Alt/Delete Stop all tests and reboot the system. R[un] Begin or resume testing (change from halt mode to run mode). Se[t] Set or display the values of state variables. Se[t] {no argument} Display a list of all state variables. Sh[ow] Show a machine state.
For example, to block test 1: RUN> block 1 Enter If you look at the test status, the display indicates that test 1 is blocked by placing the letter B next to the number of the test. To block test 1 and test 3, use either of the following: RUN> block 1 3 Enter RUN> block 1,3 Enter To block test 1, test 2, and test 3: RUN> block 1-3 Enter 3.9.2 Cache The cache command lets you set or display the state (enabled or disabled) of the internal cache.
Table 3–6 Calculate Command Qualifiers Command Description Cal[culate]/o Cal[culate]/d Cal[culate]/h Calculate using the octal radix. Calculate using the decimal radix. Calculate using the hexadecimal radix. Hexadecimal is the default radix. If you set the default radix to decimal or octal, the system immediately defaults back to hexadecimal when the calculation is finished.
You can use the following functions with the calculate command: • Add ( + ) • Subtract ( - ) • Multiply ( * ) • Divide ( / ) • Exponentiation ( ^ ) The order of precedence is: • Exponentiation (highest precedence) • Multiply or divide • Add or subtract (lowest precedence) Use parentheses to change the order. 3.9.4 Configuration The configuration command lets you display the same system and EISA bus configuration information that was displayed during initial SYSEX startup.
For example, if you select destructive (write/read) testing for a disk that really should be write protected, then you can use this command to change to nondestructive (read only) testing for the disk. Or, if you set up a COM or LPT for external loopback testing and find that loopback plugs are not installed, then you can use the devices command to reconfigure the COM or LPT for internal loopback testing only. The first argument must be the name of the requested device.

Table 3–10 Display Command Qualifiers Command Display Mode D[isplay]/b D[isplay]/w D[isplay]/d D[isplay]/a Byte (default) Word Doubleword ASCII If you do not designate an address, the system defaults to the last address selected for display or to address 0 if no previous display command was executed. Addresses have the format task:seg:offset. The task:seg fields are optional, but are always displayed by the system. The offset field is required and is the address offset within the segment.
3.9.8 Examine The examine command lets you analyze and modify data at a specified location in memory. Format: EXAMINE[/mode] [address] When data is displayed, the system cursor remains in place and waits for you to input new data. To modify the data at the current location, input the new data and then use the " , # , or Enter keys to store the new data. With or without data modification, the " key examines data at the previous location in memory. The # key examines data at the next location in memory.

5 System Configuration This chapter provides detailed information on how to use the EISA system configuration utility (SCU). 5.1 EISA Architecture The EISA bus provides an open architecture for installation of any EISA or ISA compliant option module. Specific parameters must be configured according to the option modules installed and how the system is configured.
When the SCU executes, it is able to detect automatically the system board configuration (CPUs and memory) and any EISA modules that are installed. EISA modules are detected by polling modules on the EISA bus. ISA modules are detected by the use of ISA CFG files; you define the ISA modules installed in the system. The SCU then creates a system configuration file which represents the configuration of the system.
5.2.2 When to Use the SCU Features controlled by the SCU include the following: • Select a specific keyboard type • Copy the System Configuration Diskette • Learn about configuring the computer • Set the computer date and time • Configure the computer • Maintain the System Configuration Diskette • Access the password utility Each item is available through the main menu of the SCU (see Figures 5–1 and 5–2).

5.5 Configuring the System with EISA Option Modules EISA options are shipped with an EISA CFG file. This EISA CFG file must be installed on the system configuration diskette to enable the SCU to recognize all of the features selectable on the EISA module. The SCU can automatically configure the module using the available resources. Although the system will detect the EISA option automatically, you must install the EISA CFG file to set all the configurable options on the module.
In manual verification mode, the SCU will not identify resource conflicts until you select the "Verify" option during the "View or edit details" menu. The "Verify" option does not appear unless you are in manual verification mode. Automatic configuration can be disabled for individual modules. By "locking" a board, you prevent the SCU from automatically changing the module’s resources, or suggesting a change. To lock a module: 1.
5.8 Library Diskette The EISA architecture is backwards compatible with the ISA architecture. However, since ISA modules were created and used before ISA CFG files were created, many ISA modules are in use which were shipped without ISA CFG files. In order to use these modules in EISA systems, ISA CFG files are required. To assist users of older ISA modules, many vendors have submitted ISA CFG files to the EISA consortium. These ISA CFG files are contained on the library diskette shipped with the SCU.
To use the advanced SCU feature: 1. If the system has more than 16 MB of memory, you must inform SCO UNIX that the 15 MB to 16 MB memory area is not for system use. To do this, you must edit the /etc/default/boot file. Search for the following string: DEFBOOTSTR=hd(40)unix Change it to read: DEFBOOTSTR=hd(40)unix mem=1m-15m,16m-192m/s/n You must make this change before you enable the advanced feature in the SCU.
3. Use the rotary switches on each module to set the address. (For example, set the H switch to F and the L switch to A for FA0000h, and set the H switch to F and the L switch to B for FB0000h.

B System Board Jumpers B.1 Introduction Jumper pins allow you to set specific system parameters. They are set by changing the pin location of jumper blocks. A jumper block is a small plasticencased conductor (shorting plug) that slips over the pins. To change a jumper setting, remove the jumper from its current location with your fingers. Position the jumper over the two pins designated for the desired setting. Press the jumper evenly onto the pins. Be careful not to bend the pins. B.
