AMI BIOS

User’s Guide

3-29

Optimal

Choose this option and the BIOS configures the system using the

best-case values to optimize system performance. However, these

values may not be applicable to your system. If your system does not

boot after choosing this setting, reconfigure it using the Fail-safe

settings. Refer to the following section.

The screen below appears if you choose

Optimal

from the Default

Setup menu. Select

Yes

to load the optimum values.

Fail-safe

Choose this option and the BIOS automatically configures the system

using the most stable settings. These settings are not necessarily the

best settings for system performance, but safe and stable enough to

guarantee you that your system will boot. This is useful if you are

having problems with your current system configuration and need to

determine the cause.

A prompt appears if you choose

Fail-safe

from the Default Setup

menu. Select

Yes

to load the fail-safe values.
