Tests and Error Messages
This chapter describes the MaxiLife firmware test sequences and error
messages, the pre-boot diagnostics error codes, the Power-On Self-Test
(POST) routines, which are contained in the computer’s ROM BIOS, the
error messages which can result, and the suggestions for corrective action.
MaxiLife Test Sequence and Error Messages
When the PC Workstation 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 will not
necessarily ‘freeze’ the system. However, some critical hardware errors are
fatal to the system and will prevent the system from starting (for example,
‘CPU Socket’ and ‘Power Supply’ are serious malfunctions that will prevent
the system from working correctly).
Errors that are not so critical will be detected both during pre-boot
diagnostics and POST where the BIOS boot process will return an error
code. Some errors are only detected during POST sequence, and produce
the same process.
Finally, while the PC Workstation is working, fan and temperature controls
can be reported (for example, a fan error will be reported if a fan cable is not
connected). This type of error disappears as soon as the problem is fixed
(for example, the fan cable has been reconnected).
The different diagnostics are described below.
