Chapter 1: Introduction

1-2 Chipset Overview
The Intel® 82945GC contains two components: GMCH (North Bridge) and ICH7R
(South Bridge). The GMCH is used for the host bridge, and the ICH7R, for the I/O
subsystems.
Graphics Memory Controller Hub (GMCH)
The GMCH manages the data ow between its four interfaces: the processor
interface (FSB), the system memory interface (DRAM controller), the integrated
graphics interface, the External Graphics interface, and the I/O Controller through
DMI interface. It provides bus arbitration between the four interfaces when each
initiates transactions. The GMCH supports a 32-byte Cache Line, decoding up to 4
GB (2GB for the 945GC) of the CPU's usable memory address space. The GMCH
also supports one or two channels of SDRAM and the PCI Express-based graphics
attached devices.
The Intel® 945GC platform supports the seventh generation I/O Controller Hub (In-
tel® ICH7R) to provide a multitude of I/O related features. The Direct Media Interface
(DMI) provides the chip-to-chip connection between the GMCH and the ICH7R.
Intel® I/O Controller Hub 7R (ICH7R)
The I/O Controller (ICH7R) provides the data buffering and interface arbitration
required for the system to operate efciently. It also provides the bandwidth needed
for the system to maintain its peak performance. The ICH7R supports PCI slots, Se-
rial ATA ports, USB 2.0 ports and dual channel IDE devices. In addition, the ICH7R
offers the Intel Matrix Storage Technology which provides various RAID options for
data protection and rapid data access. It also supports the next generation of client
management through the use of PROActive technology in conjunction with Intel's
next generation Gigabit Ethernet controllers.

X7SLA-L/X7SLA-H User’s Manual
1-3 PC Health Monitoring
This section describes the PC health monitoring features of the X7SLA-L/X7SLA-H.
The motherboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.
Recovery from AC Power Loss
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 hit the power switch to turn it back
on) or for it to automatically return to a power on state. See the Power Lost Control
setting in the BIOS chapter of this manual to change this setting. The default set-
ting is Last State.
Onboard Voltage Monitoring
The onboard voltage monitor will scan the following voltages continuously: CPU
Cores, Chipset Voltage, Memory Voltage (+1.8V), +3.3V, +3.3V standby, +5V, +12V,
and Vbat. Once a voltage becomes unstable, it will give a warning or send an error
message to the screen. The User can adjust the voltage thresholds to dene the
sensitivity of the voltage monitor by using SD III.
Fan Status Monitor with Software
The PC health monitor can check the RPM status of the cooling fans via Supero
Doctor III.
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning function
in the BIOS. This allows the user to dene an overheat temperature. When this
temperature reaches the pre-dened threshold, the CPU thermal trip feature will be
activated and it will send a signal to the Speaker LED and, at the same time, the
CPU speed will be decreased.
1-4 PowerCongurationSettings
This section describes features of your motherboard that deal with power and
power settings.
Chapter 1: Introduction
1-11
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blinking
to indicate that the CPU is in suspend mode. When the user presses any key, the
CPU will wake up and the LED will automatically stop blinking and remain on.
BIOS Support for USB Keyboard
If the USB keyboard is the only keyboard in the system, it will function like a normal
keyboard during system boot-up.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system
suspend button. When the user presses the power button, the system will enter
a SoftOff state. The monitor will be suspended and the hard drive will spin down.
Pressing the power button again will cause the whole system to wake up. During the
SoftOff state, the ATX power supply provides power to keep the required circuitry
in the system "alive." In case the system malfunctions and you want to turn off the
power, just press and hold the power button for 4 seconds. The power will turn off
and no power will be provided to the motherboard.
1-5 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 of 1 GHz and faster.
The X7SLA-L/X7SLA-H accommodates 12V ATX power supplies. Al-
though most power supplies generally meet the specications required by the CPU,
some are inadequate. A 2-Amp of current supply on a 5V Standby rail is strongly
recommended.
1-12
X7SLA-L/X7SLA-H User’s Manual
1-6 Super I/O
The Super I/O provides two high-speed, 16550 compatible serial communication
ports (UARTs). Each UART includes a 16-byte send/receive FIFO, a programmable
baud rate generator, complete modem control capability and a processor interrupt
system. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps as
well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which sup-
port higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Conguration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through a SMI or SCI function pin. It also features auto power management
to reduce power consumption.
