Introduction
This chapter describes the AMI BIOS setup utility for the X9DRW-CF31/X9DRW-
CTF31. It also provides the instructions on how to navigate the AMI BIOS setup
utility screens. The AMI ROM BIOS is stored in a Flash EEPROM and can be
easily updated.
Starting BIOS Setup Utility
To enter the AMI BIOS setup utility screens, press the <Del> key while the system
is booting up.
Note: In most cases, the <Del> key is used to invoke the AMI BIOS setup screen.
There are a few cases when other keys are used, such as <F3>, <F4>, etc.
Each main BIOS menu option is described in this manual. The Main BIOS Setup
menu screen has two main frames. The left frame displays all the options that can
be confi gured. Grayed-out options cannot be confi gured. Options in blue can be
confi gured by the user. The right frame displays the key legend. Above the key
legend is an area reserved for a text message. When an option is selected in the
left frame, it is highlighted in white. Often a text message will accompany it.
Note: The AMI BIOS has default text messages built in. The manufacturer retains
the option to include, omit, or change any of these text messages.
The AMI BIOS setup utility uses a key-based navigation system called "hot keys."
Most of the AMI BIOS setup utility "hot keys" can be used at any time during setup
navigation. These keys include <F3>, <F4>, <Enter>, <Esc>, arrow keys, etc.
Note 1: Options printed in Bold are default settings.
Note 2: <F3> is used to load optimal default settings. <F4> is used to save the
settings and exit the setup utility.
Note 3: For AMI UEFI BIOS Recovery, please refer to the UEFI BIOS Recovery
User Guide posted @http://www.supermicro.com/support/manuals/.
Warning: Do not upgrade the BIOS unless your system has a BIOS-related issue.
Flashing the wrong BIOS can cause irreparable damage to the system. In no event
shall the manufacturer be liable for direct, indirect, special, incidental, or consequential
damage arising from a BIOS update. If you have to update the BIOS, do not shut down
or reset the system while the BIOS is being updated to avoid possible boot failure.
