BIOS

4-1 Introduction

This chapter describes the PhoenixBIOS™ Setup utility for the X5DP8-G2/

X5DPE-G2/X5DPR-8G2+/X5DPR-iG2+/X5DPi-G2. The Phoenix ROM BIOS is

stored in a flash chip and can be easily upgraded using a floppy disk-based

program.

Note: Due to periodic changes to the BIOS, some settings may have been

added or deleted and might not yet be recorded in this manual. Please refer

to the Manual Download area of the Supermicro web site

<http://www.supermicro.com> for any changes to BIOS that may not be

reflected in this manual.

System BIOS

The BIOS is the Basic Input Output System used in all IBM

PC, XT™, AT

and PS/2

compatible computers. The PhoenixBIOS flash chip stores the

system parameters, such type of disk drives, video displays, etc. in the

CMOS. The CMOS memory requires very little electrical power. When the

computer is turned off, a back-up battery provides power to the BIOS flash

chip, enabling it to retain system parameters. Each time the computer is

powered-on the computer is configured with the values stored in the BIOS

ROM by the system BIOS, which gains control at boot-up.

How To Change the Configuration Data

The CMOS information that determines the system parameters may be

changed by entering the BIOS Setup utility. This Setup utility can be ac-

cessed by pressing the <Delete> key at the appropriate time during system

boot, see below.

Starting the Setup Utility

Normally, the only visible POST (Power On Self Test) routine is the memory

test. As the memory is being tested, press the <Delete> key to enter the

main menu of the BIOS Setup utility. From the main menu, you can access

the other setup screens, such as the Security and Power menus. Begin-

ning with Section 4-3, detailed descriptions are given for each parameter

setting in the Setup utility.
