2.4 Setup Utility

The system BIOS also contains a setup utility that enables you to change

conﬁguration settings that are stored in CMOS RAM. BIOS setup options are

the same as those provided in the "Conﬁgure computer" option of the SCU,

with the exception of password. For information on conﬁguring the system

with the SCU, refer to Chapter 5.

To run the setup utility, wait for POST to complete. Then, press the

appropriate function key to display the following initial setup screen:

**** NOTE ****

Since values specified using the BIOS Setup Utility will be overwritten when

the system configuration utility (SCU) is run, it is recommended that the BIOS

Setup Utility be used only if you:

o Need to enable your diskette drive

o Do not have access to a diskette drive

o Have only ISA expansion boards and will not be using the SCU

To exit setup press ESC. To continue setup press F1.

Note

Always use the SCU to conﬁgure the system. Do not use setup to

conﬁgure the system. Setup is used primarily to enable the diskette

drive.
