System Bios; Bios Setup Program - Digital Equipment HiNote VP 500 Series Service Manual

This chapter provides information related to the system BIOS and its Setup program.

BIOS Setup Program

The BIOS (Basic Input and Output System) Setup program is a menu driven utility that is
used to make changes to the system's configuration and tailor the operation of the notebook
computer. It is a ROM-based (Read only Memory) configuration utility that displays the
system's configuration status and provides a tool to set system parameters. These parameters
are stored in non-volatile battery backed-up CMOS RAM, which saves this information even
when the power is turned off. When the system is turned back on, the system is configured
with the values found in CMOS.
_____________________________ Note____________________________
The CMOS battery receives a charge when the system is being operated on AC
power. If the system is off for more than one year, the CMOS battery will drain
and the ROM data will be lost.
______________________________________________________________
The Setup Program is menu driven and can be used to configure items such as:
•
Hard drives, diskette drives and peripherals
•
Password protection from unauthorized use
•
Power Management Features
The settings made in the Setup program affect how the notebook computer performs. It is
important, to understand how the different Setup options affect the operation of the notebook
computer.
When turning on the Notebook for the first time you may get a message prompting you to run
the BIOS Setup program. A warning message may appear on the screen if the hardware
configuration is changed or the Power On Self-Test (POST) fails. This message will inform
you of any errors or invalid settings and prompt you to run the Setup program to correct the
problem.
