Boot Steps
. Shows the Power-On Self Test (POST) codes during the
system startup. The POST code is provided by the BIOS and is
displayed on the LCD panel as soon as it is available. If the system
stops during the startup, the last successful boot step POST code is
displayed on the LCD.
Diagnostics
. Runs a set of diagnostics assessing the system’s
components. Results of the tests are displayed on the LCD one after
another when the user presses the
button.
Result of the diagnostics is: OK/FAIL.
Error Messages
When the PC is turned on (pressing the ON/OFF button), the system
initiates the normal startup sequence. A first diagnostic (called pre-boot
diagnostics) is run to check the presence of the processor, DIMM, VRM and
power supply.
MaxiLife does not purposely ‘freeze’ the system if an error is detected.
However, some critical hardware errors are fatal to the system and will
prevent the system from starting (for example, ‘Power’, ‘Board PLL’ are
serious malfunctions that will prevent the CPU to work correctly).
Errors that are not so critical (for example, ‘CPU Socket’ for missing
terminator, or ‘NO RAM’) are also detected by the POST and will abort its
own boot process after beeping. The ‘RAM type’ error is only detected by
POST with the same abort process.
Finally, while the PC is working, fan and temperature controls can be
reported (for example, a fan error when a cable is not connected). This type
of error disappears dynamically when the problem has been fixed (for
example, the fan cable has been reconnected).
If an error is detected, a screen appears on the LCD panel. The following
table shows the test sequence carried out, the type of error message, and
the action to take.The errors mentioned are standard error codes (they are
displayed without the need of pressing any key on the LCD status panel).
