MaxiLife Test Sequence and Error Messages
Post Test Sequence and Post Error Codes
In order to check that the CPU is able to run the BIOS boot code (POST phase) from the
first CPU instructions through to DIMM detection, MaxiLife firmware waits for a
synchronization event from the BIOS. Any failure that prevents the execution of the
firmware will therefore trigger the BIOS error and will display the following message on
the LCD status panel.
Then, the BIOS executes the Power-On Self Test (POST) sequence. In this phase, MaxiLife
waits for any error messages that the BIOS may issue. If such an error occurs, then a
screen similar to the following example is displayed. The error code that appears on the
LCD status panel is the same as the one that appears on the Personal Workstation screen.
If the POST issues several error codes, only the last one is visible on the LCD status panel.
Compatibility of DIMMs. The
BIOS checks that the inserted
DIMMs are both compatible with
one another, and compatible with
the Front Side Bus frequency.
RAM TYPE
Check the installed memory modules. This
error occurs when mixing incompatible
memory modules, or when mixing
Unbuffered and Registered memory modules.
Availability of video controller. It
is checked by the BIOS. If an
error is detected, it is not a fatal
one and the BIOS will continue
its execution normally.
NO VIDEO
Check that the video controller is correctly
installed.
Note: No error is detected if a monitor is not
connected to an installed video controller.
This is not a fatal error and the BIOS will
continue its normal execution.
