Types of System Diagnostics Program Tests
System Tests
System tests help identify problems with system-board components such as processors, controllers, buses, and so on.
Select System from the system diagnostics program main menu to access the following tests:
l Processor Tests – Tests processor functionality. The system diagnostics program provides four processor tests:
¡ Basic Functionality Test – Verifies that the processor operates correctly and efficiently in all addressing modes. The test is performed in 16-bit
real mode.
¡ Processor Speed Test – Determines and displays the processor clock speed. The screen displays the expected processor speed and the actual
processor clock speed. processor speed is determined by measuring the number of processor clock cycles that occur in a known time period.
¡ CPU Protected Mode Test – Verifies the protected-mode instructions used by the operating system for switching to protected mode.
¡ Coprocessor Test – Checks the functionality of the math coprocessor. This test loads and stores the control and status word, checks data
transfer between the processor and the math coprocessor, and tests exception checking while the data transfer is in progress.
l DMA Controller Test – Performs a series of read and write tests on the memory address registers and page registers of the DMA controllers.
l Interrupt Controller Test – Performs a series of read and write tests on interrupt mask registers and checks for stray interrupts after masking off all
interrupts.
l Timer Test – Checks the accuracy of the timer count by calibrating it against the periodic interrupt of the Real Time Clock (RTC).
l Real Time Clock Test – Checks the regularity of the real time clock interrupt by calibrating it against the timer 0 interrupt.
l CMOS Validity Test – Checks the validity of the data in CMOS RAM and makes sure that the CMOS RAM checksums are correct. This test also ensures
that the battery is in good condition.
l Speaker Test – Performs test on system speaker and allows you to adjust the volume.
l PCI System Test – Scans the PCI bus for all PCI devices and checks their configurations.
l SMBus Test – Checks that the System Management Bus (SMBus) works properly. This test consists of the SMBus general test and the SMB access test.
l Hardware Monitor Tests – Reads the values for temperature, fan speed, and voltage to verify that they are within a specified range using the following
tests:
¡ Temperature and Fan Speed Test
¡ Voltage Test
Memory Tests
Memory tests, which report the size of system memory, write to all areas of installed DDR system memory up to 3 GB. The system diagnostics program isolates
faulty memory modules and displays a message that identifies the location of the faulty memory.
Keys Function
<Shift>, <Tab>, or
down arrow Moves to the next field.
Up arrow Moves to the previous field.
Right arrow Moves to the next menu.
Left arrow Moves to the previous menu.
Space bar Selects or deselects options on menus. Selected options are identified by a check mark.
<Enter> Starts a test on an individual component or displays submenus.
<Esc> Cancels the current operation or returns to the previous menu. On the main menu, <Esc> exits the system diagnostics program and
reboots the system.
For most of the options, any changes you make are recorded but do not take effect until you reboot the system. For a few options (as
noted in the help area at the bottom of the screen), the changes take effect immediately.
Key Function
<F2> Edit batch parameters.
<F3> Load batch parameters.
<F4> Save batch parameters.
<F5> Select/deselect current test.
<F6> Select/deselect All Tests in Menu.
<F7> Select/deselect All Tests.
<F8> Select/deselect All Quick Tests.
<F9> List function keys.
<F10> Run the selected test.
