Bios Setup Utility; When To Use The Bios Setup Utility - NEC HX4600 User Manual

BIOS Setup Utility

The BIOS Setup Utility, is used to change system configuration parameters. The
utility is resident in the system FLASH memory and does not require a diskette
or an operating system present to run.

When to Use the BIOS Setup Utility

In most cases, it is not necessary to run the BIOS Setup Utility to change the
default parameters, since the default settings support most system
configurations. In the following cases, however, you should initiate this utility
to change the default settings.
When the set parameters are incorrect: The parameters set with the BIOS
Setup Utility are stored to the nonvolatile memory called CMOS. If the contents
of this CMOS have been destroyed due some reason, an error message appears
on the display during the execution of POST (Power On Self-Test). When an
error message appears, press the F2 key to enter the BIOS Setup Utility.
When the CMOS is cleared: A jumper, with which you can clear the contents
of the CMOS, is provided on the system I/O board. If this jumper is used to
clear the contents of the CMOS, a message appears requesting you to run the
BIOS Setup Utility during the execution of POST. Run the BIOS Setup Utility
according to the instructions displayed on the screen and provide necessary
settings.
When the boot device priority is changed: The defaults instruct the your
server to search the boot devices in the following order: floppy disk drive, CD-
ROM drive, then the hard disk drive. If you want to change the boot order
priority, run the BIOS Setup Utility to change the settings.
When you replace a processor or memory: Your server has a degradation
function allowing continuation of operation in the event of a processor or
memory error. After replacing the failed processor or memory, run the BIOS
Setup Utility to clear the error information.
When you change cache memory configuration: Run the BIOS Setup Utility
to enable or disable the memory cache, or to set the cache in memory areas such
as system BIOS or video BIOS.
When you change a setup for a PCI or ISA board: Run the BIOS Setup
Utility to configure the interrupt request (IRQ) for PCI/ISA devices and PCI and
ISA bus slots.
