Processor Test
The Processor Test verifies the
functionality of the CPU installed in the system. Clicking on the Start button starts the
test. Clicking on the Stop button stops the test.
The Processor Test includes the
following tests which can be enabled/disabled by checking/unchecking their check
boxes:
- General Register Test:
Verifies CPU's general registers.
- Mathematical Calculation Test:
Performs arithmetic functions, such
as cos, sin, exp and etc..
- Mathematical Performance Test:
Measures the performance on above
tests.
- MMX Arithmetic Test:
Measures the performance of MMX
instructions.
- CPU Speed Test:
Performs integer division operations and
compares its performance against a speed reference table. The CPU
itself does not provide speed information. Therefore, the CPU speed is
calculated based on its mathematical performance and may be slightly different
from the one rated by the manufacturer.
Memory Test
The Memory Test verifies the integrity of
the memory installed in the system. Clicking on the Start button starts the
test. Clicking on the Stop button stops the test.
The Memory Test includes the following
tests which can be enabled/disabled by checking/unchecking their check boxes:
- Memory Address Test:
Verifies memory addressing to correct
locations.
- Data Pattern Test:
Reads and writes memory with various data
patterns.
- Walking Ones Test:
Verifies memory using walking ones
algorithm.
- Moving Inversion Test:
Verifies memory using moving inversion
algorithm.
- Walking Zeros Test:
Verifies memory using walking zeros
algorithm.
- Random Memory Block Copy Test:
Verifies memory by copying and
comparing a block of data from a random source location to another random
destination location. The Memory
Test will optimize the physical
memory size first to get the maximum continuous physical memory block for
testing. If a program requires a large block of continuous memory, this test can
also consolidate memory fragments and tune up free physical
memory size. To test all physical memory at every memory address, use the DOS
Diagnostics module's Memory Test program.
Clicking on the Free More Physical Mem... button will clean up wasted
RAM area, minimize file cache size, relocate loaded libraries to the hard drive
and free up more physical memory. This function is used when applications
require large amounts of physical memory.
I/O Port Test
The I/O Port Test verifies the
functionality of the I/O ports installed in the system. The I/O Port Test module is intended to be used by experienced users
who are familiar with setting up the standard I/O port configurations. The I/O ports
must be configured properly before running the test. Otherwise it
may generate incorrect results.
Standard I/O Port Configurations:
| Port Number |
Port Address |
IRQ Number |
| COM1 |
3F8h |

| COM2 |
2F8h |

The I/O Port Test includes both Serial Port tests and Printer Port tests. The
optional External Loopback Tests require Loopback Connectors. To make them,
please see the Loopback Connector Diagrams below. After the options are set,
clicking on the Start button starts the test. Clicking on the Stop
button stops the test. The Windows-based I/O Port Test is not available under Windows
NT, 2000 or XP. The DOS Diagnostics module's I/O Port Test is available for all systems.
The I/O Port Tests:
- Printer Port Test :
Senses port address and test
status/control registers and data port. Detach printer cable before
testing.
- Printer Port Test (with External Loopback Connector)
:
Tests printer port's operations with external loopback
connector. Checks for interrupt, control signals and data port integrity.
Enable either the Standard or Control+Data test depending on the
type of loopback connector used.
- Serial Port Test :
Senses port address and tests
status/control registers and data port. Checks baud rate accuracy and internal
data loopback function. This test will be skipped if a modem is detected on
the port.
- Serial Port Test (with External Loopback Connector)
:
Tests serial port operations with external loopback connector.
Checks for interrupt, control signals and serial data communication.
Loopback Connector Diagrams:

Read, Write, Seek and Delete operations on files with various sizes and random
data under a multi-threading environment.
The Verify
button starts low-level verifications on all physical hard drive(s). These
tests bypass the file system layer and use INT13 commands to perform Sector
Verify, Head Seek, Funnel and Random Seek tests. This test is not available
under Windows NT, 2000 or XP.
Floppy Disk Test
The Floppy Disk Test verifies the
functionality of the floppy drive(s) installed in the system. The Floppy Disk Test contains two functions:
The Start button starts the Floppy Disk Test on the selected

Read/Write and Random Read/Write tests.
The Verify button starts
low-level verifications. This test is not available under Windows NT, 2000 or
XP.
The free space left on the diskette will determine the largest file
size to be tested.
CD-ROM Test
The CD-ROM Test verifies the
functionality of the installed CD-ROM drive(s). If there is more than one drive installed, first select the
