Configuring the BIOS
This chapter provides basic information on configuring the system’s basic input/output system
(BIOS). Refer to this chapter for specific BIOS parameter settings for your
Zx

workstation. For
more information on the various parameters and settings, refer to the System Board Manual.
BIOS Overview
The system’s basic input/output system (BIOS) records basic system operating parameters, such as
the amount of memory, the boot sequence, and the type of video display. The BIOS is stored in
flash erasable-programmable memory (EPROM) on the system board, and reads the system
parameters in the system’s complementary metal-oxide semiconductor (CMOS) random-access
memory (RAM). When you power off the system, a lithium battery provides power to CMOS
RAM to retain the operating parameters. Each time you power on the system, the BIOS uses
stored parameters to configure system operation.
The BIOS Setup program, which is also stored in the flash EPROM on the system board, allows
you to manually change the system operating parameters. You can also run the BIOS Setup
program during the system’s power-on self-test (POST). For the system to operate correctly, you
should run BIOS Setup after you make any hardware changes to the system.
Using BIOS Setup
To run BIOS Setup:
Press
DELETE
when prompted during system boot.
To navigate BIOS Setup menus and parameters:
♦
Press
TAB
or an arrow key to move from one field to the next.
♦
Press
ENTER
to enter a menu or to run one of the general setup options.
♦
Press
PAGE UP
or
PAGE DOWN
to change the setting of a parameter.
The initial BIOS Setup screen lists menus, general setup options, and exit options. The rest of this
chapter provides basic information on the contents of the menus and the functions of the options.
