    SECTION Is RUNNING THE DIAGNOSTICS This section describes the System 6300 diagnostics and how to run them. TYPES OF DIAGNOSTICS There are three types of System 6300 diagnostics— subtests, tests, and test sequences. Subtests and Tests Subtests are simple checks.

  • Page 10: Special Hardware Requirements

    Running the Diagnostics sequence from a terminal, specify only the command letter that denotes the given test sequence. For example, to execute the d default test sequence, type only the letter d and press the RETURN key. Appendix A lists the test sequences that include multiple tests. SPECIAL HARDWARE REQUIREMENTS There are two special hardware requirements for running System 6300 Computer diagnostics:...

  • Page 11: Error Reporting Modes

    Parity interrupts disabled Memory tests will begin at XXXXX, end at YYYYY command» where X.X.X is the version number of the System 6300 diagnostics. XXXXX is the memory start address in hexadecimal at which memory tests start. YYYYY is the address of the last valid 32-bit word in memory.

  • Page 12: Running The Diagnostics From A Terminal

    Running the Diagnostics attended mode— either interactive, long, or continuous. (See the command format subsection below for more information.) Like unattended mode, the attended modes display errors in the top red LED in the back panel and indicate taking the interrupt in the top yellow LED.

  • Page 13: General Output Modes

    Running the Diagnostics General Output Modes The four modes for running the diagnostics are parity, page, line echo, and disk ignore. The modes are turned on and off by typing commands. Since all modes function as switches, the same commands disable the modes that enable them. For example, if you typed PM (uppercase or lowercase) to enable a mode, type PM (uppercase or lowercase) again to disable it.

  • Page 15: The Diagnostic Command

    Running the Diagnostics The Diagnostic Command The commands that run diagnostics specify • The test sequences, tests, or subtests to execute. • The number of times each test sequence, test, or subtest executes, and in which order. • The error reporting mode. The command syntax for running a simple diagnostic is as follows: [RepeatCount][:]Test[,Subtest][L/C] where...
  • Page 16 Running the Diagnostics is a letter that specifies the error reporting mode for the diagnostic and can be either L (or 1) for long mode or C (or c) for continuous mode. This parameter is optional and, if omitted, defaults to interactive. A simple diagnostic executes RepeatCount times before the "command»"...
  • Page 17 SECTION 2: TESTS AND SUBTESTS This section presents the tests in numeric order and describes the subtests available for each test. The tests are listed in Table 2-1. In addition, this section notes which tests display prompts that ask you to specify parameter values. (Each prompt specifies a default value.) Table 2-1.
  • Page 18 Testa and Subtests recognize the test specification input by the operator. If an error is present in the command line, the name of the routine that gives the message appears in parentheses (). The second type of error reports hardware malfunctions detected by the diagnostics.
  • Page 19 Tests and Subtests Subtests 1 and 7 write and read a zero (0) to each location in memory. Subtests 2 and 8 are the same as subtests 1 and 7 except that they write and read a -1 instead of 0. Subtests 3 and 9 write bit patterns of alternating 0's and l's to each address in memory.
  • Page 20 Tests and Subtests Subtest 1 operates as follows: Set register to status=valid (01). Read from the page addressed by register. Read register and check to make sure that status=accessed (10). Write to the page addressed by the register. Read register again and check to see if status=modified Subtest 2 checks meipping to the correct physical memory location and operates as follows: Write to two locations on different pages.

  • Page 21: Tests And Subtests

    Tests and Subtests register to "not valid" and then tries to write, read, and execute. Each of these attempts should generate a bus error, and the tests verify that a page fault returns. If not, the operation aborts, and an error message returns. The subtests are Test page faults caused by reading and writing.

    Tests and Subtests Errors. Test 3 can return the following errors: No Parity Interrupt at location x. BSR incorrect after parity error at location x, BSR0=x. BSRl=x. No Parity Interrupt during execution test-User mode. No Parity Interrupt during execution test-Supervisor mode. BSR incorrect after parity error during execution.

    Tests and Subtests count). This subtest operates as follows: Run timer 1 for 10 seconds. Every second, print number of seconds remaining (countdown). Check to see that Counter 2 matches the number of interrupts received. Subtest 3 programs timer 0. Subtest 3 operates as follows: Take 6,000 interrupts.

Check the status on each interrupt. Subtest 1 checks the status of the data/status register, returns the status, and makes sure that the status is valid (either line printer present, line printer selected, or line printer out of paper).

The packet size for the first transmission is four words long. For each subsequent transmission, the packet size doubles.

  • Page 39: Adding A New Test

    SECTION 3: ADDING A NEW TEST This section describes how an experienced programmer adds a new test. The procedures for running new tests must conform to the procedures for running existing tests (see the discussion on how to run tests). The following three steps are necessary to add a new test: Access the source.

    New Tests shortstring is a string saved for summary information in long mode. Longstring and shortstring can be identical strings. INTERRUPT HANDLING For interrupt handling, you must insert in trap.c a case in the switch corresponding to the vector number on which interrupts for your test will occur.
