Chapter 1: Introduction
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: VCCP,
VDIMM, 12V, 5VCC, 3.3VCC, VBAT, 5V, Dual, and 3.3V AUX. Once a voltage be-
comes unstable, a warning is given, or an error message is sent to the screen. The
user can adjust the voltage thresholds to dene the sensitivity of the voltage monitor.
Environmental Temperature Control
This motherboard comes with a built-in passive heatsink. Please follow the instruc-
tions given in your system design guide or your system user manual to provide
proper/adequate airow to your system. The onboard BaseBoard Management
Controller (BMC) monitors CPU, memory and motherboard environment tempera-
tures for fan control and PC health management.
Note : To avoid possible system overheating, please be sure to provide
adequate airow to your system.
System Resource Alert
This feature is available when the system is used with SuperDoctor® 5 in the
Windows OS environment or used with SuperDoctor II in Linux. SuperDoctor
is used to notify the user of certain system events. For example, you can also
congure SuperDoctor to provide you with warnings when the system temperature,
CPU temperatures, voltages and fan speeds go beyond predened thresholds.

1-5 ACPI Features
ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-
tion denes 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 conguration 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. A1SAi/A1SRi Series motherboards support S0 and S5 only.
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 Series motherboard alternatively supports
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 specied above. Over-current DC power use may cause damage
to the motherboard!
Note 2: Do not use the 4-pin DC power at J1 when the 24-pin ATX Power
at 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 Specication 2.02 or above. It must also be SSI compliant. (For more
information, please refer to the website 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.

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. DIMMB1/B2 are not available on A1SRi-2358F.
Note 2: The motherboard will support one, two, or four DIMM modules.
However, for best memory performance, please install DIMM modules in
pairs.
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.
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.

2-4 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.
