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 PC screen. If the POST issues several error
codes, only the last one is visible on the LCD status panel.
The following diagrams show the different BIOS-generated errors.
