4.1 About the BIOS
The BIOS (B asic Input and Output System) Setup program is a menu driven ut ility t hat enables you to
make changes to the system configuration and tailor your system to suit your individual work needs. It is
a ROM-based configuration utility that displays the system’s configuration stat us and provides you with a
tool to set s ystem parameters. These parameters are stored in non-volatile battery-backed-up CMOS
RAM that saves this information even when the power is turned off. When the system is turned back on,
the sys tem is configured with the values found in CMOS.
With easy-to-use pull down menus, you can configure such items as:
w
Hard drives, disket te drives, and peripherals
w
Video display type and display options
w
Password protect ion from unauthorized use
w
Power management features
The set tings made in the Setup program intimately affect how the c omputer performs. It is important,
therefore, first to try to understand all the Setup options, and second, to make settings appropriate for the
way you use t he computer.
4.2 When to Run BIOS
This program s hould be executed under the following condit ions:
w
When changing the s ystem configuration
w
When a configuration error is detected by the system and you are prompted to make changes to
the S etup program
w
When resetting the system clock
w
When setting the CPU clock speed so that it automatically runs either fast or slow
w
When redefining the communication ports to prevent any conflicts
w
When making c hanges t o the Power Management c onfiguration
w
When changing the pass word or making other changes to the security setup
Normally, CMOS setup is needed when the s ystem hardware is not consistent with the information con-
tained in the CMOS RAM, whenever the CMOS RAM has lost power, or the sy stem features need to be
changed.
