1-3 Special Features

Recovery from AC Power Loss

Basic I/O System (BIOS) provides a setting for you to determine how the system will

respond when AC power is lost and then restored to the system. You can choose

for the system to remain powered off, (in which case you must press the power

switch to turn it back on), or for it to automatically return to a power-on state. See

the Advanced BIOS Setup section to change this setting. The default setting is

Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the board. All have

an onboard System Hardware Monitoring chip that supports PC health monitoring.

An onboard voltage monitor will scan these onboard voltages continuously: CPU

1-5 ACPI Features

ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-

tion denes a exible and abstract hardware interface that provides a standard

way to integrate power management features throughout a PC system, including

its hardware, operating system and application software. This enables the system

to automatically turn on and off peripherals such as CD-ROMs, network cards, hard

disk drives and printers.

In addition to enabling operating system-directed power management, ACPI also

provides a generic system event mechanism for Plug and Play, and an operating

system-independent interface for conguration control. ACPI leverages the Plug and

Play BIOS data structures, while providing a processor architecture-independent

implementation that is compatible with Windows 7, Windows 8, and Windows 2008

Operating Systems.

1-6 Power Supply

As with all computer products, a stable power source is necessary for proper and

reliable operation. It is even more important for processors that have high CPU

clock rates.

Note 1: The A1SAi and A1SRi MB series motherboard alternatively sup-

ports a 4-pin 12V DC input power supply for embedded applications. The

12V DC input is limited to 12A by design. It provides up to 144W power

input to the motherboard. Please keep onboard power use within the power

limits specied above. Over-current DC power use may cause damage to

the motherboard!

Note 2: Do not use the 4-pin DC power @J1 when the 24-pin ATX Power

@JPW1 is connected to the power supply. Do not plug in both J1 and

JPW1 at the same time.

It is strongly recommended that you use a high quality power supply that meets ATX

power supply Specication 2.02 or above. It must also be SSI compliant. (For more

information, please refer to the web site at http://www.ssiforum.org/). Additionally, in

areas where noisy power transmission is present, you may choose to install a line lter

to shield the computer from noise. It is recommended that you also install a power

surge protector to help avoid problems caused by power surges.

the DIMMs module upwards.

Module Notch

Side Clips

Module Key

Socket Key

Installing DIMM Memory Modules

1. Align the key on the bottom of the DIMM module against the receptive point

on the memory slot. Take note of the notches on the side of the DIMM mod-

ule, and of the locking clips on the socket to avoid causing damage.

2. Install the DIMMs module straight down into the socket until it is securely

seated in the socket. The side clips will automatically lock the module into

place.

Populating Memory Modules

Note 1: Install the desired number of DIMMs into the memory slots, starting

with DIMMA1, then DIMMB1, then DIMMA2, then DIMMB2. Pay attention

to the notch along the bottom of the module to prevent incorrect DIMM

module installation.

Note 2: Insert each DIMMs module vertically and snap it into place. Repeat

step 1 until you complete the memory installation. See the section below

for more details on DIMM memory installation.

Note 3: Insert only identical memory modules of the same part number

into the memory slots to ensure that only memory modules of the same

type, same frequency, same speed and same capacity are used on the

same motherboard.

Caution: 1) To avoid damaging the motherboard and its components, please do

not use a force greater than 8 lb/inch on each mounting screw during motherboard

installation. 2) Some components are very close to the mounting holes. Please take

precautionary measures to avoid damaging these components when installing the

motherboard to the chassis.

2-4 Motherboard Installation

All motherboards have standard mounting holes to t different types of chassis.

Make sure that the locations of all the mounting holes for both motherboard and

chassis match. Although a chassis may have both plastic and metal mounting fas-

teners, metal ones are highly recommended because they ground the motherboard

to the chassis. Make sure that the metal standoffs click in or are screwed in tightly.

Then use a screwdriver to secure the motherboard onto the motherboard tray.

Connectors (JPW1, J1, J3)

The 24-pin ATX power connector header

(JPW1) is used to provide power to the

motherboard. The 4-pin DC Power con-

nector, located at J1, provides alternative

12V power source for space-restrained

enclosures such as SC101i when JPW1

is not in use. The 4-pin HDD Power

connector J3 provides power to onboard

HDD devices.

A

Note 1: Do not use the 4-pin

DC power at J1 when the

24-pin ATX Power at JPW1 is

connected to the power supply.

Note 2: Refer to Section 1-6

in Chapter 1 for proper power

use.

Fan Headers (Fan 1 ~ Fan 3)

The A1SAi & A1SRi Series motherboard has

three fan headers (Fan 1~Fan 3). These fans

are 4-pin fan headers. Although pins 1-3 of the

fan headers are backward compatible with the

traditional 3-pin fans, we recommend the use

4-pin fans to take advantage of the fan speed

control via Pulse Width Modulation through the

BMC. This allows the fan speeds to be auto-

matically adjusted based on the motherboard

temperature. Refer to the table on the right for

pin denitions.

2-7 Jumper Settings

Explanation of Jumpers

To modify the operation of the mother-

board, jumpers can be used to choose

between optional settings. Jumpers create

shorts between two pins to change the

function of the connector. Pin 1 is identied

with a square solder pad on the printed

circuit board.

Note: On two-pin jumpers,

"Closed" means the jumper is on,

and "Open" means the jumper is

off the pins.

A. LAN PortS Enable or

CMOS Clear

JBT1 is used to clear CM O S . In stead of pins, this "jumper " consists of co nt ac t pa d s

to prevent accidental clearing of CMOS. To clear CMOS, use a metal object such

as a small screwdriver to touch both pads at the same time to short the connec-

tion. Always remove the AC power cord from the system before clearing CMOS.

Note 1: For an ATX power supply, you must completely shut down the

system, remove the AC power cord, and then short JBT1 to clear CMOS.

Note 2: Be sure to remove the onboard CMOS Battery before you short

JBT1 to clear CMOS.

Note 3: Clearing CMOS will also clear all passwords.

Chapter 4

BIOS

4-1 Introduction

This chapter describes the AMI BIOS setup utility for the A1SAi & A1SRi Series

motherboard. The ROM BIOS is stored in a Flash EEPROM and can be easily

updated. This chapter describes the basic navigation of the AMI BIOS setup utility

setup screens.

Note: For AMI BIOS Recovery, please refer to the UEFI BIOS Recovery

Instructions in Appendix C.

Starting BIOS Setup Utility

To enter the AMI BIOS setup utility screens, press the <Delete> key while the

system is booting up.

Note: In most cases, the <Delete> key is used to invoke the AMI BIOS

setup screen. There are a few cases when other keys are used, such as

<F1>, <F2>, 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 congured. Grayed-out options cannot be congured. Options in blue can be

con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. Supermicro 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 the

setup navigation process. These keys include <F1>, <F4>, <Enter>, <ESC>, arrow

keys, etc.

Note: Options printed in Bold are default settings.

How To Change the Conguration Data

The conguration data that determines the system parameters may be changed by

entering the AMI BIOS setup utility. This setup utility can be accessed by pressing

<Del> at the appropriate time during system boot.

Appendix C

UEFI BIOS Recovery Instructions

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

Supermicro be liable for direct, indirect, special, incidental, or consequential damages

arising from a BIOS update. If you need to update the BIOS, do not shut down or reset

the system while the BIOS is updating to avoid possible boot failure.

C-1 An Overview to the UEFI BIOS

The Unied Extensible Firmware Interface (UEFI) specication provides a software-

based interface between the operating system and the platform rmware in the

pre-boot environment. The UEFI specication supports an architecture-independent

mechanism for add-on card initialization to allow the UEFI OS loader, which is stored

in the add-on card, to boot up the system. UEFI offers a clean, hands-off control

to a computer system at bootup.

C-2 How to Recover the UEFI BIOS Image (-the Main
BIOS Block)

A UEF BIOS ash chip consists of a recovery BIOS block, comprised of two boot

blocks and a main BIOS block (a main BIOS image). The boot block contains critical

BIOS codes, including memory detection and recovery codes for the user to ash

a new BIOS image if the original main BIOS image is corrupted. When the system

power is on, the boot block codes execute rst. Once that is completed, the main

BIOS code will continue with system initialization and bootup.

Note: Follow the BIOS Recovery instructions below for BIOS recovery

when the main BIOS boot crashes. However, when the BIOS boot block

crashes, you will need to follow the procedures in Appendix D.

C-3 To Recover the Main BIOS Block Using a USB­Attached Device

This feature allows the user to recover a BIOS image using a USB-attached device

without additional utilities used. A USB ash device such as a USB Flash Drive, or

a USB CD/DVD ROM/RW device can be used for this purpose. However, a USB

Hard Disk drive cannot be used for BIOS recovery at this time.

item- "Proceed with ash update" and press the <Enter> key. You will see the

progress of BIOS Recovery as shown in the screen below.

Note: Do not interrupt the process of BIOS ashing until it is com-

pleted.

To perform UEFI BIOS recovery using a USB-attached device, follow the instruc-

tions below.

1. Using a different machine, copy the "Super.ROM" binary image le into the

disc Root "\" Directory of a USB device or a writeable CD/DVD.

Note: If you cannot locate the "Super.ROM" le in your driver disk, visit

our website at www.supermicro.com to download the BIOS image into

a USB ash device and rename it "Super ROM" for BIOS recovery use.

2. Insert the USB device that contains the new BIOS image ("Super.ROM") into

your USB drive and power on the system

3. While powering on the system, keep pressing <Ctrl> and <Home> simultane-

ously on your keyboard until your hear two short beeps. This may take from a

few seconds to one minute.

4. After locating the new BIOS binary image, the system will enter the BIOS

Recovery menu as shown below.

Note: At this point, you may decide if you want to start with BIOS Recov-

ery. If you decide to proceed with BIOS Recovery, follow the procedures

below.
