MaxiLife Hardware Monitoring Chip 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. Error! BIOS 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. Error! POST XXXX Where XXXX = POST error code The following diagrams show the different BIOS-generated errors. "BIOS" ERROR BIOS "read DIMM 1" MaxiLife "Spy DIMM 1" There is a timeout of 3 seconds before the message is displayed on the LCD status panel and video display. DIMM 1 Error! BIOS LCD Status Panel 9
