MaxiLife Hardware Monitoring Chip MaxiLife Test Sequence and Error Messages MaxiLife Test Sequence and Error Messages When the PC is turned on (pressing the ON/OFF button), the system initiates the normal startup sequence which is composed of the following steps: • Basic pre-boot diagnostics. • BIOS launch. • POST phase. • Operating System boot phase. If any errors are detected during the startup sequence, MaxiLife does not purposely 'freeze' the system. However, some critical hardware errors are fatal to the system and will prevent the system from starting (for example, 'Power', and 'Board PLL' are serious malfunctions that will prevent the CPU from working 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 checks 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). The different diagnostics are described below. Basic Pre-boot Diagnostics The first diagnostic (called basic pre-boot diagnostics) is run to check the presence of the processor(s) or terminators, VRMs, power supply, CPU Board PLL and DIMMs. The pre-boot diagnostic tests are run in order of priority with respect to their importance to computer functions. Refer to the table Basic Pre-boot Diagnostics, on page 8 for test sequences, failure messages and action to take to solve any problems. The first detected error displays a message on the LCD status panel. If this happens, one of the following screens could appear. 6
