3 USING THE BIOS SETUP
UTILITY
BIOS Setup is a utility programmed into the computer’s read-
only memory (ROM). Its main purpose is to allow you to view
and alter the computer’s hardware configuration. It is also used
to configure the on-board security system. The current
configuration is kept in a special area of memory, called CMOS
memory, and maintained by a small battery. BIOS Setup can be
accessed whenever the computer is turned on or rebooted.
This chapter describes how to access and use BIOS Setup, with
the exception of the security system functions. For information
on configuring the security system, see Chapter 6, “Using the
Security System”.
Accessing BIOS Setup
To prevent unauthorized reconfiguration, the security system
can disable access to BIOS Setup for individual users.
To access the BIOS Setup utility:
1. Turn on or reboot the computer (for example, press
CTRL+ALT+DEL in MS-DOS).
2. If the security system is enabled, logon to the computer
using an account that includes the right to access the
BIOS Setup utility.
BIOS sign-on and hardware configuration messages are
displayed, either in text or graphics format according
to how the startup mode is currently configured.
3. In text mode, press the ALT+S key combination when
invited to do so. In graphics mode, use the mouse to
click on the Setup button (or press ALT+S while the
button is displayed).
The main BIOS Setup dialog box appears once POST
is completed.
