Monitoring Post While Running; Verifying Proper Operation Of Key System Indicators - NEC HX4500 User Manual

Monitoring POST While Running

Each time you turn on the system, POST runs automatically and checks the
system board, CPU, memory, keyboard, and most installed peripheral devices.
During the memory test, POST displays the amount of memory that it is able to
access and test. Depending on the amount of memory, it may take several
minutes to complete the memory test. When the memory test completes, the
following is displayed:
Press <F2> to enter SETUP
Press < > if you want to run BIOS Setup. When the utility appears, follow the
F2
instructions on your monitor to configure BIOS. See Chapter 4, "Configuring
Your System." If you do not press <
seconds and the boot process continues.
When this message appears:
Press <Ctrl><A> for SCSISelect™ Utility!
Press <
Ctrl
utility appears, follow the instructions on your monitor to configure the SCSI
host adapter settings and run the SCSI disk utilities. See Chapter 4,
"Configuring Your System." If you choose not to run the SCSISelect Utility, the
boot process continues.
If POST finds an error, it displays an error message. This information is useful
to your service representative. Refer to the Error Message section in this chapter
for an explanation of each error code.
The BIOS indicates errors by writing an error code to the PS/2-standard logging
area in the Extended BIOS Data Area, and by displaying a message on the
screen, which is sometimes preceded by the POST Error Code. The error code
will also be logged to the Event Logging area.

Verifying Proper Operation of Key System Indicators

As POST determines the system configuration, it tests for the presence of each
mass storage device installed in the system. As each device is checked, its
activity indicator should turn on briefly. Check for the following.
T
Does the diskette drive activity indicator turn on briefly. If not, refer to
Diskette Drive Activity Indicator Does Not Light in this chapter.
T
If a second diskette drive is installed, does its activity indicator turn on
briefly. If not, refer to Diskette Drive Activity Indicator Does Not Light in
this chapter.
T
If there is a hard disk drive or SCSI devices installed in the system, does
the hard disk drive activity indicator turn on briefly. If not, refer to Hard
Disk Drive Activity Indicator Does Not Light in this chapter.
